Full textAbstract:
The aim of the thesis is to analyse how to measure an economic pillar of sustainable urban development when it is understood in terms of qualitative city development. This principly means achieving economic prosperity which does not lead to damage of the city areas and decrease the quality of life for its residents. This approach requires the creation of an appropriate set of indicators that will cover qualitative aspects of sustainable economic development. The first section summarizes existing approaches to the definition of sustainable development and ways of measuring both on the Czech and the international level. There are also defined basic characteristics of the urban development which are appropriate to express a qualitative development of the city. The second part is focused on existing ways in which sustainable development is measured, i.e. especially in the context of indicator sets. These are under detailed assessment which aim is to show how useful is to measure the economic sustainability from the qualitative point of view. In this part, the limits of using economic macro aggregates (especially Gross Domestic Product) is emphasized because there are still regarded as one of the key economic indicators of sustainable development. In the next part the thesis deals with the definition of economic prosperity and focuses on the characteristics typical for short, medium and long term perspective. Measurement of sustainable urban development in the short term is based on assessment of financial situation. From the medium-term point of view, it is crucial to assess how the city handles its property, i.e. mainly buildings and land. These property components are substantial for a further direction of city development. In the next section are designed indicators aimed at measuring the ability of the city to maintain a skilled workforce which is one of the most important conditions of long-term economic prosperity. The final theoretical part of the thesis is focused on how the long-term sustainable urban development is to be expressed in an economic way through the assessment of investments in urban infrastructure and its operational efficiency. The designed set of indicators is verified on case studies of three medium-sized Czech cities.

Full textAbstract:
In this thesis the applicability of ocean environment modelling as a part of optimal naval operational efficiency, and thus military oceanography, is evaluated. To be able to do this, the principles of knowledge-based warfare and the ability to make rapid environmental assessments, are introduced. These then form part of optimal efficiency. Modelling of the environment implies knowledge-based warfare and accommodates the ability to make a rapid environmental assessment. After an overview of past and current ocean modelling (specifically wave modelling), the third generation SWAN (Simulating WAves Nearshore) model is selected to model a small component of the military oceanographic spectrum viz. waves. The selected area, includes an area where the US Navy conducted an amphibious landing exercise (Operation Laurel) during October 2001. Three case studies are considered for modelling. These included an extreme wave condition, a mode wave condition and the conditions during Operation Laurel. Data were obtained from the wave rider buoy at Slangkop near Cape Town and analysed for a specific period during 2001. In all three cases the wave dissipation and maximum energy transfer areas were determined from the model. From these, certain deductions could be made regarding the influence the environment under these three different conditions could have on naval operations in the littorals. It is concluded that ocean modelling should form an integral part of naval operational efficiency and its contribution as force multiplier should be taken into consideration.

Full textAbstract:
The aim of this research was to contribute towards energy efficiency in the shipping industry through improved operational practices that reduce fuel consumption, hence exhaust emissions and the amount of carbon dioxide released into the atmosphere. This is in line with meeting global emission reduction targets and the mitigation of Climate Change. A critical review is presented that was undertaken to understand Climate Change as a driver towards energy efficiency within the maritime industry. The regulations are reviewed along with existing operational practices and the enablers and barriers towards improvements. Several field studies that were undertaken to further examine current practices and barriers are described, including a questionnaire identifying the opinions and perceptions of seafarers. Based on conclusions from the review and field studies, a Framework for improving the energy efficiency of ship operations is presented. The proposed Framework identifies that for practical solutions in the industry, human factors must be addressed in parallel with technical advances. The following features of the Framework to enable improvements are identified to be: a) Ship Operational Performance Monitoring for performance feedback distribution and supporting operational strategic decisions and b) updates to existing Operating Procedures. However, it is proposed that these features cannot be achieved on a wide scale without first the development of the following elements: a) Maritime Education and Training on energy efficiency; b) Analysis of ship Operational Profiles; c) A Ship Operational Performance Prediction (SOPP) Model. These three elements were developed and are described in this thesis. The developments described in this thesis were enabled by the collection of operational datasets (namely Ship Reports, also commonly known as Noon Reports) and information for 21 case study ships; including tanker, container and bulk carrier ships. The collection of this data was enabled by field study visits. Regarding the development of Maritime Education and Training on energy efficiency, three course curriculums are proposed. The training material developed for the Energy Resource Management course is then described. The results from the analysis of Operating Profiles for the 21 case study ships are presented. Typical operating practices are identified along with the opportunities for energy efficiency improvements. The Ship Operational Performance Prediction Model was developed using the Ship Report dataset for a case study tanker ship. The model predicts the ship's main engine brake power and fuel consumption with adequate accuracy and allows for assessment of the impacts due to different operating conditions. Specifically, a function to account for time dependent performance changes is developed so that the hull and propeller surface degradation and fouling are taken into consideration. Finally, the utilisation of the developed elements within the proposed Framework to improve energy efficiency is discussed, so that the importance of methods utilising Ship Report operational datasets becomes evident.

Full textAbstract:
The British economy has always been a trading nation in terms of goods and more recently services. At the heart of the nation and international trading is London, the hub of a global financial empire that unites the globe on a 24-hour basis. Vast revenues are generated by commercial and investment banking institutions, yet research in this sector has been comparatively low. Management researchers have instead gravitated towards the ‘back office’ operations of high street banks or general insurance company call centres (Seddon, 2008). Research has focused on repetitive clerical activities for customers, and how these businesses suffer from ‘failure demand’ and/or ‘demand amplification’ (Forrester 1961) created when a customer is forced to re-establish contact with a call centre to have their issue/concerns reworked (when it should have been ‘right first time’). Modern commercial and investment banks do not share the repetitive and relatively predictable transactions of call centres and instead, represent extreme operations management cases. The workload placed upon commercial and investment banking systems is incredibly high volume, high value and high variety in terms of what clients’ demand and how ‘the product’ (trades) is executed. At this period in time, the financial collapse of 2008 is still shaping working practices due punitive regulatory environment. Many UK banks are now part-owned by the government, there is social and political pressure to stimulate improvement in banking operations which – it is thought – will herald the return of the banks back to private ownership. This thesis addresses the flow of global “trades” through the operations office and explores how the design and fit of the sociotechnical environment provides effective and efficient trade flow performance. The key research questions emerging from the literature review establishing the gap in knowledge are 1) How efficient are commercial and investment banking trading processing systems? And 2) What are the enablers and inhibitors of efficient and high performance of industrialised processing systems? xviii To answer these questions, the researcher undertook an in-depth and longitudinal case study whilst at a British bank that was ‘benchmarked’ as underperforming against its peers (MGT Report1, 2011). The case study strategy was executed using an action research and reflective learning approach (cycles of research) to explore the performance and improvement of banking operations management performance. The findings show that, using systems feedback, the management at the bank were able to develop into a “learning organisation” (Senge 1990) and improve and enhances the flow of work through the system. The study has resulted in significant gains for the case study and a new model of Rolled Throughput Yield is presented that rests on the key concept of “Information Fidelity”. This work marks a contribution to the operations management body of knowledge by exploring “flow” under conditions of high volume and high variety and from within the under-researched context of commercial and investment banking. 1 “MGT” is an anonymised commercial and investment banking industry report into operational efficiency and cost performance. The report was commissioned by the participant banks and conducted by “MGT Consultants” and is considered highly confidential. The researcher was given a copy of the report while working with the case, forming as the catalyst for the research into operational performance. The researcher was unable to receive “MGT Consultants” agreement to ‘directly’ cite the report as part of this study.

Full textAbstract:
Open pit mines constitute more than half of global minerals production. Yet most of the large, high-grade, and close to the surface deposits have been depleted or are currently in production. Besides, volatility in commodity prices and stringent environmental regulations limit the up-scaling expansions in large open pits. Consequently, the mines are determined to increase their operational efficiency in order to thrive. This has recently led to major metallurgical improvements in the processing of ores; whereas the improvements in mining of the said ores are relatively overdue in terms of efficiency and technological advancement. This thesis concentrates on the mining activities and their efficiency in open pits with a focus on drilling, blasting, loading, and crushing. As all of these tasks revolve around the fragmentation of run-of-mine ore, their relationships and efficiencies are explored within the context of fragmentation. Fragmentation is a result of complex interactions between rockmass, blasting geometry, explosive, and timing sequence of blast holes. The influence of rockmass and timing sequence on fragmentation and efficiency are explored, as well as the target fragmentation for efficient loading and crushing. Moreover, the techniques for measuring fragmentation are evaluated as to whether they can benefit mines in terms of efficiency. As the circumstances in open pits are essentially site-specific, these issues are addressed as a case study of the Aitik mine in Sweden. The research comprised four elements. First, the influence of rockmass fractures on blast results and downstream efficiency was evaluated via full-scale field trials. The fractures in and around the case study mine were mapped using a photogrammetric technique and six production blasts were adapted to the major fracture sets to evaluate the effect of initiation direction on downstream efficiency. Second, the influence of the timing sequence of blast holes was explored within the theories of stress waves interaction and their consequent effect on fragmentation. Theoretical and numerical solutions were accompanied by six field trials in full-scale to evaluate the influence of short delay times on fragmentation and efficiency. Third, an empirical study was conducted to correlate fragmentation to the efficiency of loading and crushing; this was done to define a target fragmentation for the studied case. Finally, the techniques to assess fragmentation were discussed both quantitatively and qualitatively. The findings indicated that rockmass fractures have a significant influence on the quality of blasts and efficiency of downstream tasks. In the case study mine, adjustments to orientation of drill pattern and initiation direction of blasts suggested that careful experimentation in this regard can yield a favourable initiation direction with respect to existing discontinuities. Finer fragmentation and higher loading efficiencies can be achieved by adapting the blast designs to the existing fractures, which can lead to significant savings in the long run. On the contrary, the influence of stress waves interaction on blast results turned out to be marginal. Neither the theoretical and numerical solutions nor the field trials showed any significant improvements in blast results from short delays. In fact, it was found rather implausible to expect any noticeable improvements by using short delays. The empirical method to evaluate target fragmentation proved useful as well. It was shown that by incorporating different data from various sources in a mine, one can follow the ore from muckpile to loaders and then to crushers. Having a qualitative understanding of the fragmentation, and by developing tools to measure efficiency, one can estimate what fragmentation is most favourable for an efficient operation. Finally, two image-based methods to assess fragmentation were discussed in terms of repeatability and statistical significance. It was found that the scatter in both methods is rather large, introducing a certain ambiguity in representativeness of their results. Admittedly, it was found that in matters of long-term efficiency, the number, size and representativeness of assessed samples are of more importance compared to the accuracy of individual measurements.

Full textAbstract:
The study of the improvements to transport controlling facilities, defined in this dissertation as operational transport upgrades, aims to ascertain its influence on a growing urban traffic demand. This dissertation assesses the influence that the conversion of Werner List Street into a one-way street has on the performance of traffic accommodation. Werner List Street links traffic commuting from the south to the north of Windhoek's Central Business District (CBD). The CBD traffic demand is estimated to breach network capacity by 2015, a scenario prevalent in many small middleweight cities. The research conducted a literature review on aspects related to the development and implementation of operational upgrades; thereby gaining an understanding on the relevance that such improvements have on small middleweight cities. Studied literature suggests that with the reduction in the allocation of funds to develop transport systems, transport authorities resort to innovative methods of improving transport network utilising minimal capital expenditure. The limited funding is prevalent in small middleweight cities due to the current lack of major traffic impediment. The research studied aspects of Windhoek's activity system, as presented in the city's Household Survey of 2004 that primarily focused on the income status, transport mode use and transport mode preference. The origin of trips would assist in determining the direction, in relation to Windhoek's CBD, peak traffic commutes.

The three essays of this dissertation investigate the insurance equilibrium from various perspectives. The first essay uses Cournot game-theoretic model to study the insurance contract formation and provides theoretical justification for policy limit. The second essay introduces buyers' heterogeneous risk aversion into Wilson's equilibrium, derives new equilbria, and provides the conditions under which those new equilibria will hold. The third essay studies the operational efficiency of life insurers in China. Through comparing the efficiency of domestic and foreign life insurers, decomposing their efficiency scores, figuring out the directions and potential they could improve, and analyzing the change and driver of productivity, the essay gives insights of the fast-developing life insurance industry in China.

Full textAbstract:
With the rapid growth of housing development in China, energy inefficiency in domestic architectures is becoming a crucial problem for the nation's sustainable development. At present, the average energy consumption of housings in North China cities is three times that in developed countries. The energy conservation regulation introduced by the government requires 65% heating energy saving in dwellings compared with the 1980's standard. However most of the current buildings cannot meet that regulation the problem is mainly due to the lack of detailed technology and construction requirements, and difficulties in relation to enforcement. The main aim of this research is to investigate the potential of using environmental design strategies to increase the energy efficiency of residential architectures in North China cities while provide reasonable comfort conditions. Literature review, on-site observations, field experiments and computer simulation were used. The field experiments were conducted in five flats in Tianjin and Xi'an cities to assess their thermal performance. Thermal simulations by using the building energy model HTB2 were employed to analysis these designs, and what improvements can be reasonably achieved, in line with China's targets for reducing housing energy demand by adapting certain environmental design strategies. The findings of this work showed that with the adaptation of environmental design strategies, significant improvements of energy efficiency of residential buildings in North China cities can be achieved and considerable portion of energy can be saved. The most effective parameter in heating reduction is improve thermal insulation, having 50mm and 100mm polystyrene insulation achieved reductions of 26.5% and 38.8‰ respectively. Reduce the infiltration rate is the second most effective method, limit the air change rate to 0.5 ach reduced 21.6% of the heating demand from the existing condition. The parameters that reduce most cooling demand are having a reasonable window area and night time controlled ventilation the reduction rate is around 23% and 13% respectively. Moreover, combining appropriate design parameters will maximise their effectiveness in energy reduction. Having parameters including appropriate glazing ratio, improve insulation of the building envelope, reduce infiltration etc. will enable case studies to match the 65% saving regulations straightforward and the cooling load was also substantially reduced. Moreover, by following further modification suggestions, the energy reduction rate reached 90%. Considerable reduction in energy use and carbon emission can be achieved in North China cities and other places experiencing similar climates, by adapting the suggested design strategies. The findings of this research could help the decision-makers and architects to improve thermal performance and energy efficiency of both existing housings and future designs.

to enhance value creation and profitability.
The study begins by discussing the origin, history and evolvement of Six
Sigma into a methodology recognisable and espoused by leading world class

Full textAbstract:
Over half of the world’s population lives in urban areas, a trend which is expected to only grow as we move further into the future. With this increasing trend in urbanisation, challenges are presented in the form of the management of urban infrastructure systems. As an essential infrastructure of any city, the energy system presents itself as one of the biggest challenges. As cities expand in population and economically, global energy consumption increases and as a result so do greenhouse gas (GHG) emissions. To achieve the 2030 Agenda’s sustainable development goal on energy (SDG 7), renewable energy and energy efficiency have been shown as key strategies for attaining SDG 7. As the largest contributor to climate change, the building sector is responsible for more than half of the global final energy consumption and GHG emissions. As people spend most of their time indoors, the demand for energy is made worse as a result of maintaining the comfort level of the indoor environment. However, the emergence of the smart city and the internet of things (IoT) offers the opportunity for the smart management of buildings. Focusing on the latter strategy towards attaining SDG 7, intelligent building control offers significant potential for saving energy while respecting occupant comfort (OC). Most intelligent control strategies, however, rely on complex mathematical models which require a great deal of expertise to construct thereby costing in time and money. Furthermore, if these are inaccurate then energy is wasted and the comfort of occupants is decreased. Moreover, any change in the physical environment such as retrofits result in obsolete models which must be re-identified to match the new state of the environment. This model-based approach seems unsustainable and so a new model-free alternative is proposed. One such alternative is the reinforcement learning (RL) method. This method provides a beautiful solution to accomplishing the tradeoff between energy efficiency and OC within the smart city and more importantly to achieving SDG 7. To address the feasibility of RL as a sustainable control strategy for efficient occupant-centred building operation, a comprehensive review of RL for controlling OC in buildings as well as a case study implementing RL for improving OC via a window system are presented. The outcomes of each seem to suggest RL as a feasible solution, however, more work is required in the form of addressing current open issues such as cooperative multi-agent RL (MARL) needed for multi-occupant/multi-zonal buildings.

This thesis covers work done at National Grid to improve resource planning and the execution of pipeline construction and maintenance work carried out at the yards. Resource Planning, the art of picking the right jobs for the right days and assigning the right crews to them while meeting constraints of regulation, customer service, and safety at the minimum cost is an extremely difficult problem. This is exacerbated by the fact that there needs to be enough slack in the system to deal with one or more pipeline leaks that may be called in. At the execution stage, when the jobs are carried out by crews, the lack of standardization in work processes dealing with granting and approval of overtime, productivity tracking, data collection, and imperfect alignment of incentives make it difficult to get the best work from the crews. These issues lead to high levels of overtime at yards, which are the major source of costs for gas operations for the company. We propose the Resource Allocation and Planning Tool (RAPT) accompanied by yard level process management to improve operations performance. To automate short term planning, RAPT includes a two stage stochastic optimization model to perform job scheduling and crew assignment in the presence of a variable number of emergency leaks, thus creating optimal daily and weekly plans with minimal overtime costs. The tool also serves as a business intelligence platform, providing a companywide view of gas operations efficiency and as a decision aid, enabling management to predict the impact of management policies on field operations. The execution of work was improved by the creation of new processes for scheduling, crew data entry, overtime approval, incorporating accountability and oversight at multiple levels. This work has enabled more consistent processes, better overtime and productivity management, and the ability to understand and track deviations. These changes are currently being piloted at yards across the company and the initial results are very encouraging. As a direct result of this work, National Grid has the potential to achieve up to 65% reduction in overtime, saving the company a substantial amount of money.

Full textAbstract:
Studying recurrent mobility perturbations, such as traffic congestions, is a major concern of engineers, planners, and authorities as they not only bring about delay and inconvenience but also have consequent negative impacts like greenhouse gas emission, increase in fuel consumption, or safety issues. In this dissertation, we proposed using the resilience concept, which has been commonly used for assessing the impact of extreme events and disturbances on the transportation system, for high-probability low impact (HPLI) events to (a) provide a performance assessment framework for transportation systems' response to traffic congestions, (b) investigate the role of transit modes in the resilience of urban roadways to congestion, and (c) study the impact of network topology on the resilience of roadways functionality performance. We proposed a multi-dimensional approach to characterize the resilience of urban transportation roadways for recurrent congestions. The resilience concept could provide an effective benchmark for comparative performance and identifying the behavior of the system in the discharging process in congestion. To this end, we used a Data Envelopment Analysis (DEA) approach to integrate multiple resilience-oriented attributes to estimate the efficiency (resilience) of the frontier in roadways. Our results from an empirical study on California highways through the PeMS data have shown the potential of the multi-dimensional approach in increasing information gain and differentiating between the severity of congestion across a transportation network. Leveraging this resilience-based characterization of recurrent disruptions, in the second study, we investigated the role of multi-modal resourcefulness of urban transportation systems, in terms of diversity and equity, on the resilience of roadways to daily-based congestions. We looked at the physical infrastructure availability and distribution (i.e. diversity) and accessibility and coverage to capture socio-economic factors (i.e. equity) to more comprehensively understand the role of resourcefulness in resilience. We conducted this investigation by using a GPS dataset of taxi trips in the Washington DC metropolitan area in 2017. Our results demonstrated the strong correlation of trips' resilience with transportation equity and to a lesser extent with transportation diversity. Furthermore, we learned the impact of equity and diversity can mostly be seen at the recovery stage of resilience. In the third study, we looked at another aspect of transportation supply in urban areas, spatial configuration, and topology. The goal of this study was to investigate the role of network topology and configuration on resilience to congestion. We used OSMnx, a toolkit for street network analysis based on the data from OpenStreetMap, to model and analyze the urban roadways network configurations. We further employed a multidimensional visualization strategy using radar charts to compare the topology of street networks on a single graphic. Leveraging the geometric descriptors of radar charts, we used the compactness and Jaccard Index to quantitatively compare the topology profiles. We use the same taxi trips dataset used in the second study to characterize resilience and identify the correlation with network topology. The results indicated a strong correlation between resilience and betweenness centrality, diameter, and Page Rank among other features of a transportation network. We further looked at the capacity of roadways as a common cause for the strong correlation between network features and resilience. We found that the strong correlation of link-related features such as diameter could be due to their role in capacity and have a common cause with resilience.Doctor of Philosophy
Transportation infrastructure systems are among the most fundamental facilities and systems in urban areas due to the role they play in mobility, economy, and environmental sustainability. Due to this importance, it is crucial to ensure their resilience to regular disruptions such as traffic congestions as a priority for engineers and policymakers. The resilience of transportation systems has often been studied when disasters or extreme events occur. However, minor disturbances such as everyday operational traffic situations can also play an important part in reducing the efficiency of transportation systems and should be considered in the overall resilience of the systems. Current literature does not consider traffic performance from the lens of resilience despite its importance in evaluating the overall performance of roads. This research addresses this gap by proposing to leverage the concept of resilience for evaluation of roadways performance and identifying the role of urban characteristics in the enhancement of resilience. We first characterized resilience considering the performance of the roadways over time, ranging from the occurrence of disruptions to the time point when the system performance returns to a stable state. Through a case study on some of the major highways in the Los Angeles metropolitan area and by leveraging the data from the Performance Measurement System (PeMS), we have investigated how accounting for a proposed multi-dimensional approach for quantification of resilience could add value to the process of road network performance assessment and the corresponding decision-making. In the second and third parts of this dissertation, we looked at the urban infrastructure elements and how they affect resilience to regular disruptive congestion events. Specifically, in the second study, we focused on alternative transit modes such as bus, metro, or bike presence in the urban areas. We utilized diversity and equity concepts for assessing the opportunities they provide for people as alternative mobility modes. The proposed metrics not only capture the physical attributes of the multi-modal transportation systems (i.e. availability and distribution of transit modes in urban areas) but also consider the socio-economic factors (i.e. the number of people that could potentially use the transit mode). In the third study, we investigated how urban road networks' form and topology (i.e., the structure of roadway networks) could affect its resilience to recurrent congestions. We presented our findings as a case study in the Washington DC area. Results indicated a strong correlation between resilience and resourcefulness as well as topology features. The findings allow decision-makers to make more informed design and operational decisions and better incorporate the urban characteristics during the priority setting process.

Full textAbstract:
This thesis explores the concept of sustainability in the context of the community expectation for sustainability in cities. Effective sustainability performance requires all three pillars of environmental sustainability (stewardship), social equity and economic efficiency to achieve complementary outcomes rather than simply individual outcomes. For cities, one challenge of sustainability is centred on urban form, transport characteristics and the interactions between these and the communities they support. Better understanding of these dynamics is an important step in a meaningful interpretation of sustainability performance of cities. Reviews of methodological gaps in sustainability performance of cities are framed into a statement of problem. Gaps include a holistic assessment framework, methodologies to better understand urban dynamics, the drivers that produce sustainability performance and to objectively measure the performance of all three pillars of sustainability. The common transport planning and land-use planning methods are identified as suitable building blocks for improvements in sustainability assessment, and accessibility is established as an important part of sustainability. In a new approach to sustainability analysis, a sustainability framework is formulated. A concept of "environmental sustainability - accessibility space" is introduced as a novel visualisation of sustainability performance. Propositions are formed that a city's sustainability performance can be analytically quantified and simply visualised in terms of the three pillars of sustainability. Sydney, a global city with a history of planning, is the case study to empirically test the propositions, with the sustainability framework providing the conceptual reference points. Having developed a picture of the urban dynamics in the Sydney case study, the proposed sustainability metrics are developed and the propositions tested. Sustainability metrics consisting of three typologies are shown to indicate the sustainability performance characteristics for the three pillars of sustainability in terms of data set shape, frequency and spread in the "environmental sustainability accessibility space". The visualisations although built from many thousands of pieces of data provided a simple representation giving a holistic view of the sustainability characteristics and trends. Collectively, the sustainability framework, sustainability metrics, companion urban dynamics metrics, and urban system measures are demonstrated as a meaningful methodology in assessing city sustainability performance.

Full textAbstract:
Security Operation Centers (SOCs) have become an integral component of business organizations all over the world. The concept of a SOC has existed for a few years now yet there is no systematic study documenting the occurrences of their operations. A lack of documented operational knowledge makes it a challenge for security researchers interested in improving operational efficiency through algorithms, tools, and processes.
SOC environments operate under a secrecy culture as a result of which researchers are not trusted by analysts and their managers. This lack of trust leads to only superficial information through methods such as interviews. Moreover, security analysts perform their tasks using hunches that are difficult to articulate and express to an interviewing researcher. This knowledge is called tacit knowledge. Capturing rich tacit knowledge is crucial for researchers to build useful and usable operational tools.
This thesis proposes use of long-term participant observation from cultural anthropology as a research methodology for security researchers to study SOC analysts and their managers. Over a period of four and a half years seven students in Computer Science, graduate and undergraduate, were trained by an anthropologist in using fieldwork techniques to study humans. They then took jobs as security analysts at five different SOCs belonging to academia and corporations.
We made unexpected discoveries in pursuit of tacit operational knowledge. The first discovery was identification of human capital mismanagement of analysts as the root cause of analyst burnout. Specifically, a vicious cycle among analyst skills, empowerment, creativity, and growth causes analysts to lose morale and eventually leave the job. In fact burnout is a manifestation of number of tensions that are inherent in a security operations setting. This leads to our second discovery of recognizing and managing contradictions as a prerequisite for SOC innovation. Failure to acknowledge them can lead to dysfunctions in a SOC such as analyst burnout. Informed by the findings regarding the social aspects of SOC operations we attained the intended goal of capturing tacit operational knowledge. The thesis documents our experience in tacit knowledge capture through design of a framework for detecting phishing emails in near real-time.
Studying human aspects of security operations and cyber-security in general must be done within a social and organizational context. This thesis proposes long-term participant observation of practitioners and end-users as a viable methodology to conduct cyber-security research in general.

The study was done within the local government environment. It was conducted with the aim of assisting municipalities to achieve optimum levels of operational efficiency, following the realisation that all over the world there is an increasing need for organisations, including government organisations, to become efficient. One of the major challenges facing governments worldwide is the need for them to supply basic services to their populations, who are increasing at a disproportionate rate to the resources available to sustain and improve the quality of life of these people. Thus for government to overcome these challenges, it needs to utilise its available resources cautiously to be able to meet these escalating challenges effectively. Therefore, ten practices were presented in this study as key instruments capable of bringing about efficiency to the manner in which local government operates or delivers services. It was found during the literature review that when these practices are deployed, they will ensure the achievement of operational efficiency within the local sphere of government.
The empirical study was conducted in Matjhabeng Local Municipality (MLM), located in the Northern region of the Free State Province. This local municipality came into existence on the 5th of December 2000 after the amalgamation of the former six transitional local councils into one financially viable and economically sustainable municipality. It incorporates the city of Welkom and the towns of Virginia, Odendaalsrus, Hennenman, Allanridge and Ventersburg, with an estimated population of more than 500 000 people. During the background review of the municipality, several challenges were encountered which included parts of the population without access to proper sanitation and electricity. However, in all the municipal challenges presented, it was argued that the solution can be found in the effective management of municipal input with relation to its output, which means that the municipality has the huge task of managing its scarce resources in an efficient manner to be able to deliver on its mandate and to meet the expectations of its residents. Furthermore, the study was conducted from a sample consisting of the four senior managers and twenty line managers from the four departments within the municipality. A representative sampling method was employed to ensure that all relevant aspects (such as race, gender and department), considered important for selecting a sample, are included and to also obtain global responses from respondents selected to participate in the study. Furthermore this sample was drawn from a population of nine senior managers and 35 line managers. The research was conducted with the expressed permission from the office of the accounting officer. Different impressions of the responses made by the participants from this municipality were obtained and then analysed. Overall, there was a negative response from the majority of the participants regarding most of the questions on the ten practices identified. Moreover, in terms of the devised model for measuring efficiency of the municipality based on three levels, the most desirable being Level 3, it was found that the municipality could be classified as a Level 1 organisation, which means that the municipality is at an elementary phase as far as achieving efficiency in its operations is concerned. Lastly, recommendations were made based on the findings of the empirical research conducted.Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2009.

The present work addresses an operational inefficiency problem at a semiconductor equipment manufacturing warehouse, Varian Semiconductors Associates and Equipment (VSEA). This problem is important because if unresolved, the warehouse is unable to meet the part delivery time target of 24 hours during the busy period. The downstream effects of the late part delivery are delayed production schedules and in the worst case scenario, a missed shipment to the customer, which is very costly. In order to improve the efficiency of the warehouse so as to consistently deliver parts on time, the picking efficiency needs to be enhanced. Parts are primarily picked from two types of storage locations - GL shelves and Vertical Lift Modules (VLMs). The picking efficiency can be improved by the simultaneous reduction in workload on GL and improvement in the VLM picking efficiency. The first part of this thesis focuses on improving the picking inefficiency at the VLMs by employing a more efficient picking method. From our time study, we find that the pick-and-consolidate (parallel picking) is more efficient than pick-and-pass (sequential picking). The average makespan time savings per order by pick-and-consolidate is 8% (20 minutes). The second part of this paper discusses what is required to maintain a high VLM picking efficiency. New metrics to measure the workload distribution of the VLMs and the average flow time per order are proposed. Three dynamic slotting methods that maintain a balanced workload distribution across the VLMs without the need for periodic review are also examined. The methods are evaluated based on how balanced is the workload distribution across the VLMs and the cost of implementation.

Resource and knowledge recombination activities of manufacturers, suppliers, and service providers have evolved with the advent of globalization and increased market complexities. Such changes in resource and knowledge recombination activities have enabled and advanced the relevance of well-forged and properly implemented collaborative partnerships. Collaborative partnerships are credible alternatives in the provision of goods and services. The participants in this multiple case study design were 12 senior business managers from three oil, gas, and energy companies in a metropolitan area in a western province of Canada. Participants revealed the strategies they used to forge profitable collaborative business partnerships. The resource-based view (RBV) and the relational view (RV) constituted the conceptual framework of this study. Data were collected were using semistructured face-to-face interviews and analysis of organization documents. Member checking preceded the final data analysis process. The modified van Kaam method served to manage the emerged themes. Themes that emerged from data analysis included planning, organizing, and managing work; decision-making; leadership; people, relationship management; and managing complexities. The findings of this study may contribute to social change through the interdependencies that collaborative partnerships promote and encourage among employees of the collaborating organizations. Collaborative partnership interdependencies create the opportunities and conducive environments that might enable people from different cultures, and with different and inimitable capabilities, skills, and resources to cohabit peacefully and to work together productively.

With GDP growing rapidly, ownerships and uses of private vehicles have increased dramatically and have worsened traffic situation. Road transportation systems, especially private vehicles are highly dependent on fuel and result in environmental pollutions. Therefore, how to develop public transportation to elevate transportation efficiency has become an important issue. The purpose of this study is to examine the impacts of urban form on operational efficiency of mass transit by using, 19 cities in East Asian as sample. This study began with a cluster analysis to categorize the sample cities into two groups, the following criteria: population density, GDP per capital and proportion of aging population. Then, this study applied Data Envelopment Analysis to evaluate the relative efficiencies of the sample cities in two groups. Finally, the factors affecting operational efficiency of mass transit were explored by Tobit regression model, and considerable strategies of urban form were drawn based on the empirical evidence. The major empirical findings are as follows: (1) The sample cities can be categorized into two groups: developed cities and developing cities. (2) The results of DEA show that operational efficiencies of the developed cities were significantly higher than that of the developing cities, and the pure technique efficiency is the highest index among all efficiency indexes. (3) Most sample cities were in the phase of decreasing returns to scale and they need to improve their effectiveness by decreasing inputs of mass transit systems. (4) The results of Tobit regressions indicate that the environment variables result in different effects on operational efficiencies between the two city groups.

This study investigated the operational performance of logistics and warehousing industries of various counties/cities in Taiwan from 1991 to 2006. In addition, data envelopment analysis was used as the operational performance assessment model, where the number of employees, labor remuneration, floor area, and net value of fixed assets were used as input, gross output was used as output, and current assets were used as intermediate goods. Efficiency analysis, slack analysis, Malmquist productivity index analysis, and dynamic network DEA were performed in order to understand the general status of the operational efficiency of logistics and warehousing industries of various counties/cities. Moreover, this study investigated the direction and range of efficiency improvement and provided such information as reference for development of governmental regional industrial policies and improvements of regional industrial competitiveness. Efficiency analysis found that, in the past 15 years, an increasing return to scale was observed in the development of logistics and warehousing industries in 23 counties and cities in Taiwan. The operational scale has room for expansion, and was at the growth phase of the industry life cycle. Malmquist productivity index analysis showed that, from 1991 to 2006, the average change of total factor productivity, technical efficiency, and technological innovation were all greater than 1. Such information suggested that, over the past 15 years, technical efficiency and technological innovations of logistics and warehousing industries in Taiwan made significant progress. In consideration of the effects of inputs, deferred outputs, and intermediate goods, as opposed to static DEA, dynamic network DEA had greater application to the assessment of the operational performances of regional industries.

This study focuses on the impact of labor unemployment concerns on corporate operational efficiency. This research adopts the unemployment insurance data published by the US states to capture labor unemployment concerns, and follows the calculation results of the DEA approach in the Demerjian et al. (2012) to measure firms’ operational efficiency. To test our hypotheses, this study employs data for US listed companies during the period from 2004 to 2014. The empirical results indicate that unemployment concerns are negatively associated with operational efficiency. That is, firms with higher unemployment concerns have lower operational efficiency. Moreover, the results also confirm that with greater numbers of operating segments, the negative association between unemployment concern and operational efficiency will be stronger.

ASEAN has promoted the development of its intra-regional economic integration through air cargo trade and investment by targeting business persons to travel throughout the region for business and sightseeing. More and more passengers are projected to enter the market annually for the foreseeable future, the airline sector and new airline companies are continually growing in this region. This study explores the efficiency of fifteen ASEAN airlines covering the period 2010-2014 by using data envelopment analysis (DEA) models, disaggregated input efficiency measures, and bootstrapping approaches. For strategic and competitive insights, this paper aims to measure and benchmark comparative operating efficiencies of major airlines in ASEAN, and presents a new interpretation along with managerial implications. The disaggregate input efficiency of ASEAN airlines is computed by comparing the target and actual inputs. The disaggregate input efficiency of ASEAN airlines shows that aircraft efficiency is the lowest, operating cost efficiency is better, and available seat efficiency is the best. The region’s airline policy needs to be in line with promoting transportation efficiency, such as upgrading out-of-date aircraft, slowing down the rate of expansion. or an open sky policy to extend flight connectivity networks to all parts of the globe. ASEAN’s LCC policy needs to set a matching strategy to promote transportation efficiency. Relative infrastructure investment for air transport can indirectly promote airline efficiency and rapidly increase air transport traffic demand. ASEAN should engage in not only relative strategic policy changes and technological advances, but also execute significant improvements in managerial practices. Strategic suggestions are made to improve the operational efficiency of ASEAN airlines, we hope our finding contribute to theory and management practice.

In Taiwan, aging population as well as disabled population is rising in a constant pace. More and more senior citizens are arranged in the long term care facilities due to changes in social environment, family structures and family functions. Rapid increase of elderly population also causes the increase in need for long term care facilities. According to the statistics of the Department of Health, Executive Yuan, the numbers of nursing homes in Taiwan grew 11.86 times from 29 in 1997 to 373 in 2009. Therefore, the assessment of nursing home quality and management performance is becoming widely concerned. This study focuses on nursing homes to explore the related model between operating efficiency and quality of care by evidence based research. Twenty-three institutions from Taichung County are selected as the study target. Our research making use of the evaluation results of the local health authority to analyze nursing home qualities and management performance. Data envelopment analysis (DEA) is used to evaluate the management performance of the target nursing homes and to compare the management efficiency among different categories of nursing homes. Based on the DEA model, five input and four output variables are selected and analyzed by super efficiency model analysis. The twenty-three institutions are categorized according to ownership, affiliation and scale to compare their quality by statistical Mann-whitney U test. Our findings are summarized as follow. 1. In terms of performance efficiency: (1) Average technique efficiency is 1.2644. (2) Average pure technique efficiency is 1.7885. (3) Average scale efficiency is 0.8346. (4) Only 2 out of 23 DMUs are relatively inefficient. (5) There is no significant difference between public and private nursing homes, neither between hospital affiliated and independent institutions. With respect to scale, institutions with more than 70 beds are appeared to be more efficient. 2. In terms of quality of care: (1) For indexes such as residential safety, services provided, professional consultant and care plan, public nursing homes generally perform better than private owned institutes. (2) For indexes such as residential safety, emergency facilities and overall environment, hospital affiliated nursing homes generally have better rating than independent institutions. (3) There are no significant differences in all quality indexes among institutions of different scale. 3. In terms of the correlation between performance efficiency and quality of care: Public nursing homes appear to be significant negatively correlated. Our results not only serve as an important basis for institutional managers to figure out their management problems, but also as basic principles to help manage their institutions efficiently. In addition, our study provides reference information for nursing home managers to redirect their future tasks and administration, as well as to examine whether their limited resources are used appropriately. Moreover, we hope that our study also provides as a valuable reference for the government to establish policies for elderly care.

Applying the four-stage data envelopment analysis (DEA) approach proposed by Fried et al. (1999), this thesis studies the operational environment-adjusted efficiency of eleven nationwide banks in China from 1995 to 2004. In addition to managerial factors, the operational environment also brings favorable and unfavorable effects to banks. This study attempts to separate the inefficiency caused by management and inefficiency caused by operational environment. There are two outputs (investment and loans) and three inputs (deposits, employees, and fixed assets) in the DEA model. All nominal variables are transformed into real variables by the GDP deflators at the 1995 price level. After adjusting the input variables by excluding effects caused by environmental factors, state-owned banks have a greater improvement on efficiency. This implies that the joint-equity ownership significantly favors nationwide banks in China. State-owned banks can hence engage in ownership reform to improve their efficiency.

The port, which provides the place of the cargo handling, affects several factors of the operational efficiency related mutually among the ships, the wharfs, the handling equipments, the cargo handling times, the ports, the ship owners, and the shippers. In particular, Kaohsiung port has been confronted by the port competition of Asia. And, how to promote the operational efficiency is definitely an important lesson for the development of the port. Studying through the handling system by now is that we have tried to realize the problems during handling operations. The author has made certain strategy to improve the handling operations. What’s more, causing the regression analysis to discuss that could affect the factors of the operational efficiency between of A and B container terminal centers. Meanwhile, could afford the direction of the improvement. According to the aforementioned, we can advance the following strategy effective for studying： Ⅰ Since the system gets high possibility of the breakdown, we’ll instead of the older equipments in time that can effectively manage and save the time on the system. However, we certainly earn the time to improve the trucks standing by. As that time, maintaining the equipments and parts should renew them as following on the schedules. On maintaining tasks well, the practicability absolutely will be raised. Ⅱ To enhance the basic equipments, to keep working normally and to cultivate the staff of terminal operation companies whose services have high quality, we should operate the aggressive attitudes. As long as we constantly improve the ways availably, we can get the best advantages. Ⅲ Both of terminal planners and terminal operators should update and settle the modern port for the development of globe economy instead of the operational of untimeliness. By conditional on hand, we made the port develop and let it be more the foresight and valuable.

The moves taken by the government recently in releasing financial control to meet with the challenges of financial liberalization and these resulted in extreme competition among commercial banks. Under the keen competition environment, in order to attain production efficiency, commercial banks have to consider and offer their services and commodities that will maintain their profitability and solve the problem of operation strategies. The operations of commercial banks can have the efficiency promoted through consolidation of business management procedures and corporate functions and to financial industry with knowledge service industry characteristics, the operation needs particularly the injection of human resources to carry out related business, and the accumulation and structuring of human resources related activities are of human resources management features and can bring commercial bank with intangible human capital. However, intangible assets are characterized with difficulty in measure. Since Bassi & Van (1999) presented method of measuring intangible capital, scholars’ literatures shifted their attention on intangible asset from the definition and method of measuring to the management of intangible asset gradually, which became intangible capital of creating business value. Expenditures on human capital management activities should have been valuable intangible asset, but as constrained by accounting practices, the expenditures were treated as expense. This article is to emphasize on converting these expenses into capital and consider the effect of the increased capital to business operating efficiency. Therefore, we placed the human resources management activities of financial industry as intangible asset and to capitalize them to reflect the human resources management activities in the production process. Seiford and Zhu (1999) proposed a operation process of commercial bank in the perspective of creating market efficiency of business and with input-output productivity or efficiency theoretical model, incorporate the effect of corporate management of intangible assets to actually the scientific data of the difference. This research design is based on the operation process of Seiford and Zhu (1999) and took the adjusted intangible assets as one of the inputs to conduct efficiency analysis of commercial banks in Data Envelopment Analysis (DEA), and determine the effect of the adjusted intangible assets on the operational efficiency and marketability efficiency in the production process of commercial banks. In order to demonstrate the influence of intangible asset – human resources management activities on production efficiency, the empirical research divide the results into Guidepost Group and Contrast Group for convenient in comparison and analysis. The Guidepost Group has total asset as input item of production process and the Control Group divides total asset into tangible asset and adjusted intangible asset, and takes the two assets as inputs. Further, this research takes commercial banks in Taiwan area as the samples and the observation period is between 2002 and 2007. DEAP Version 2.1 Software is employed to obtain the input oriented single period production efficiency and Malquist Index (MI) of Guidepost Group and Control Group under Data Envelopment Analysis (DEA). In addition to study in detail the difference of efficiencies at different stages of different groups, the empirical results of the two groups are analyzed to reveal the effects of human resource management activities on the production efficiency of commercial banks. Through empirical analysis, we have come to conclusion that it is understood that by inputting in human resources management activities, banks’ operation efficiency can be raised and the operating revenue can be increased, and under varying scale, human capital can also lead the operation flow smoother and improve he scale reward to the best condition. Also, it is found that under different environment and conditions, banks inputs of human capital can greatly improve individual bank operation efficiency and marketability efficiency and maintain the market competitiveness.

ABSTRACT To cope with the competitive trend of liberalization and globalization, the management of financial institutions in Taiwan is under a survival pressure and is thinking about how to uplifting its performance. Because Taiwanese banking management is using “Branch System”, the performance of each bank relies on the efficiency of its branches. To evaluate the efficiency of each branch, the management of the financial institutions often uses a performance evaluation approach, but the approach involves subjective factors and is not able to indicate the improvement scale and aspect needed by inefficient branches. This study uses the efficiency evaluation method - Data Envelopment Analysis (DEA) to measure 81 branches of one bank in Taiwan, using input/output oriented mode as well as CCR and BCC models to obtain operational efficiency, pure technical efficiency and scale efficiency. An empirical result would be analyzed and suggestions would be made by this study to provide decision making references to the management of the bank. The summary of this research’s result are as follow: 1.According to input/output variables, the operational efficiency of 81branches is all the same. However, the analysis results of technical efficiency and scale efficiency among inefficient branches aren’t quite alike. Among the 81 branches, only 8 branches are relatively efficient (the ratio is about 9.9%) and 73 branches are inefficient (the ratio is a high 90.1%). 2.By examining the relation of the location of the branches and their efficiency values, we could find the most efficient branches are located in the Taoyuan-Hsinchu-Miaoli region. The greater Taipei region ranks second. Although most branches are located in Taipei, since this is a much more competitive market, their operational efficiency isn’t as high as one would expect. Judging by the urbanization of the locations of the branches, we find that the most efficient ones are located in the cities. Therefore, the locations of the branches and their efficiency have some relation. 3.By using the DEA method to evaluate the efficiency value of each branch, the result is less different with the existing group. The main difference between DEA and performance evaluation is the distributions of weights. The weights of DEA come from linear programming, and the weights of earnings of the performance evaluation is 50%. Technically, the DEA method is used to find out the reasons for the increase of efficiency of different branches. However, economically, whether or not this increase of efficiency is worthwhile still needs further analysis. 4.According to the result of the DEA method, among the branches that have an efficiency value of 1, some of them have a poor performance in practice. This shows that the input/output operational efficiency of these branches’ productive essentials is higher than the other branches. As for the meaning of reference frequency, generally the more reference frequencies taken represents the evaluated unit is relatively more stable and efficient. According to the research of substantial evidence, this study finds that the more a branch is referred to (bench mark) merely shows other evaluated branches have similar input/output ratio, production mode or production criteria. Through the sensitivity analysis, we deleted branch D5 and C17 for they are the most referenced branches in input-orient mode (they both belong to group 3). We reran DEA afterward and found that the branches with much more reference frequencies are still centralized around D5 and C17, proving the validity of this theory.

With the rise of global awareness of climate change mitigation, corporate environmental responsibility has been increasingly valued by the community. In light of this, this study examined the concept of sustainable low-carbon economy, exploring how various types of managers efficiently respond to climate change mitigation, and their efforts towards managing a low-carbon enterprise. The sample for the study is comprised of 142 Japanese firms from different industries listed in the Nikkei 500 and the S & P Japan SME index between 2008 and 2012.This research adopted the data envelopment analysis (DEA) method which combines sustainable economy and sustainable environment through a empirical analysis in order to observe the Japanese managers’ ability of fulfilling their commitments to reducing annual carbon emissions and their performance differences in management efficiency. The results show that regarding the performance in management efficiency, small and medium enterprises (SME) in the non-environmentally sensitive industries performed the best in the period of stable economy. However, when facing a volatile economy, large-scale enterprises in the non-sensitive industries performed better compared to their SME counterparts in operational efficiency integrated with the evaluation of environmental investment. In order words, the comprehensive ability of large-scale enterprises to solve crises and shoulder corporate environmental responsibility was better than that of SME in the non-sensitive industries. However, the management of SME in the environmentally sensitive industries performed the worst in management efficiency pertaining to maintaining sustainable economic growth and taking environmental responsibility. Based on these indicators, carbon intensity (carbon-intensive) and environmental expenditure budget, SME in the non-sensitive industries outperformed their counterparts in utilizing and controlling resources. Contrarily, the managers of large-scale enterprises in the non-sensitive industries did not efficiently use resources to reduce total carbon emissions. These findings has major contribution to filling the gap in empirical studies by incorporating small and medium enterprises as a research subject and also to providing evidence of how different types of Japanese coporate management were committed to reducing carbon emissions effectively while pursuing economic sustainability.Last but not least, this research can certainly help industries plan futures policies.

This study uses data envelopment analysis to investigate the operating efficiency of 96 listed biotechnology firms between 2014 and 2016 and further explore the factors that influence the operating efficiency. The results reveal that 19 firms showed an operating efficiency of 1 throughout the 3 years. For the firms that did not achieve the satisfactory efficiency, this study suggests that they adequately allocate the resources to be invested to increase the operating efficiency. Furthermore, this study divides the influencing factors into two types. The first type comprises general factors. We found that the operating efficiency is influenced by both listing location and the year of establishment. The second type comprises factors related to corporate governance. However, the effects that the shareholding ratio of managers, the board chairperson concurrently serving as the general manager, the shareholding ratio of blockholders, and foreign investors’ shareholding ratio have on the firms’ operating efficiency are nonsignificant.

This study uses Data Envelopment Analysis (DEA) to evaluate the operating efficiency of civil airports in Taiwan from 2004 to 2007 (consisting of 18 airports with 72 decision-making units), and applied regression analysis to examine the effects of environmental variables on the performance. The results of the study indicate that 17 DMUs in overall efficiency (OE), 31 DMUs in pure technical efficiency (PTE), 17 DMUS in scale efficiency (SE) are efficient relatively. However, all of the OE, PTE, and SE are getting worse year after year. The results of regression analysis find that the location (on or off-shore island), site characteristics (megalopolis or non-megalopolis), GDP, and the running of Taiwan high speed rail influence the performance of these airports significantly. According to the result of slack variable analysis, this study provides a few suggestions to improve the efficiency for non-efficiency DMUs.

We apply the data envelopment analysis (DEA) approach to compute city efficiency scores with and without environmental factors considered. Observations include forty-four cities in China during the 1998-2003 periods. There are two ouputs (local government income, population) and eight inputs (employment population, foreign investment, local government expenditure, city electricity consumption, sulfur dioxide emissions quantity per square kilometer, industrial wastewater passing rate, environmental noise passing rate,and built-up areas afforestation coverage) in our DEA models. Moreover, DEA generates the target environmental factors for each region in cities in each year, from which the efficient environmental variable-saving target ratios of regions in cities can be computed. All nominal variables are transformed into real variables at the 1998 price level by GDP deflators. Our major findings are as follows: 1. Efficiency scores of big cites such as Beijing and Shanghai will get down after considering environmental factors. 2. Efficiency scores of cities in China were generally improing during the analysis period. 3. Given the environmental factors, the largest cities could not bear any more population inflow; however, middle- and small-sized cities sill could absorb more poluplation inflow. 4. The Mann-Whitny U test shows that the east cities have significantly higher efficiency scores than the central cities and the central cities have significantly higher efficiency scores than the west cities.

After financial holdings have founded in Taiwan, how to find out the bench mark financial holdings is attached importance to the government organization. We chose the Data Envelopment Analysis (DEA), Principal Component Analysis (PCA) to measure the operation efficiency of financial holdings, and compare their consistence. In this paper a ranking method is presented within the DEA. Based on the super efficiency ranking method which ranks only the efficient units, we used DEA supper efficiency multistage ranking, G/DEA presented by Hadad et al. ( 2003 ), ranks the inefficient units and efficient units. The other ranking method is presented by Premachandra（2001）, who describes a joint use of DEA and principal component analysis (PCA) in ranking of decision making units. But Premachandra（2001） used only DEA supper efficiency to rank the inefficient units and efficient units. We improve Premachandra（2001）’s method by using DEA supper efficiency multistage ranking to rank the inefficient units and efficient units. Through the two ranking methods to evaluate the performance of financial holdings in Taiwan, we find that there exists consistency between the rankings obtained from G/DEA and PCA.

The proprietary funds, which belong to central government, are settled as businesses organizations according to economic construction, social development and multi-public affairs organizations. However, these funds are not easy for public to oversee, due to their variety and complicated businesses that are not easy to go deep into. Finally, many defects are arousing. Besides, the funds bring many defects all the time, for the management of these funds are only focus on budget-achieved, but neglect to control cost and to use the resource efficiently. The operational efficiency of the proprietary funds should be raised and looked upon, especially when the financial of our government is getting tough. The purpose of this research is for judge how the funds are operating and inspect the relative efficiency among the funds. We analyze the operation from 87 to 90 of the 13 funds based upon the DEA model. We try to develop an objective formula to estimate the overall efficiency, technical efficiency and scale efficiency for each fund. The results will become reference for future distribution. Besides, in order to prove that the DEA model is suitable to analyze these multi-input and multi-output non-benefit organizations, we draw back the range of the funds to add the relative similarity. We take the 10 airports, which belong to CAA Operating Fund as the research sample for discuss the operating efficiency. Finally, in order to mark up for the defect that DEA model cannot make beyond yearly analyze, we adapt Malmquist productivity index to make long-term analyze and to compare for realizing how the technique and efficiency changes. According to the result: 1.First, in accordance with the proprietary fundsWe examine the percentage of business plans carry-out working, and then find that there are 2 efficient funds and 3 more inefficient funds during the sampling survey. The inefficient result depends upon pure technical inefficiency. Refer to productivity changes, there are only 3 funds’ productivity raise within 3 years when we compare with those of 87’ year. The other funds have unstable productivity changes. Second, when we estimate the operating revenue condition of each fund, there are only 2 efficient funds and 2 more inefficient funds during the sampling survey. When we compare with the funds in 87’, there are 4 funds with raised productivity, the other funds with declined producticity. The decrease of productivity depends upon pure technical inefficiency and scale inefficiency. 2.Refer to airports, which belong to CAA Operating FundDuring the sampling survey, there are 4 funds efficient each year, the other are inefficient, which are caused by both pure technical inefficiency and scale inefficiency. Regarding to productivity changes, in 88’ year, only 7 airports have raise productivity. During the rest 2 years, all airports have declined productivity. Technical retrogression is the main reason, which leads to productivity decline.

The 1997 global financial crisis has complicated the acceptance of risk in financial institutes with The Basel Accord; hence, the Basel Committee searched for public comment in 1999 followed by the revised draft of Basel Capital Accord announced in 2001. Published in 2004, the implement of the Accord took place in 2006. This article concludes as follow: 1.By putting market risk capitals products and credit risk capitals products as the variables in Basel II standard, the findings include: credit risk capitals products prompt major difference among banks; the increase of market risk capitals products reflects that banks no longer profited solely from granting loans but promoting related products; and the decrease of debited risk capital products may be resulted by the effort in fewer irrecoverable loans. 2.The comparison between BCC model and SBM model finds: the effect value variance confirms the major difference in two models; more rigid limitations in SBM model reveals lower effect value and higher degree in the variance between effect values than BCC model; and precise evaluation between upper and lower banks. In the ranking of performance, majority of banks are listed in the first category in the models, and the ranking presents the positive relationship. The rigidness of SBM finds one and two false efficiency banks in 2004 and 2005. Due to the limitation of researching subjects, the research followed The Basel Accord; The Revised Basel Capital Accord does provide more diverse and flexible risk evaluations in the purpose of maintaining the financial stability and decreasing the negative effects on financial institutes. Hence, the attempt of future research followed by The Revised Basel Capital Accord may be needed in the related field.

Light-emitting diode (LED) upstream and midstream industries have experienced merging tide and only few new companies joined in since 2005. However, new applications such as better cooling dice and higher light emission are still expanding, and thus many new companies rushed into the LED downstream field. Unfortunately, some are facing financial losses, and this might attribute to their operational inefficiency. Data Envelopment Analysis (DEA) is applied to evaluate operational efficiency of 9 public LED downstream companies in Taiwan. Inputs consist of quantity of employees, expenses for R&D and management, and their fixed assets between 2004 and 2006. The only one output is annual revenue. Multistage DEA model is used to rank companies’ super efficiency scores, whose relation to their profitability by return on equity (ROE) is then tested by Spearman rank correlation. Malmquist productivity index is also applied to compare these companies’ cross-year efficiency. This study concludes that companies’ ranking between efficiency and profitability is loosely correlated. Efficient companies are not necessarily profitable; in other words, operational efficiency is not the only and main factor of financial success for LED downstream industries. Finally, some operational strategies to LED downstream industries are suggested. Keywords: LED; Operational efficiency; DEA

The purpose of this study is to investigate the relationships among executive compensation, corporate risk and operational efficiency. The data was collected from 2005 to 2009, including 419 companies in Taiwan. According to the theory of risk premium and pay-for-performance, considering many important variables, such as market risk, credit risk, operational risk, total asset turnover and days-inventory turnover, we specify some hypotheses to discuss how those variables impact on executive compensation. The results show that the market risk and revenue risk have a positive effect on executive compensation. This fulfills the risk premium theory：corporations give a higher compensation to managers who take a higher risk. However, the credit risk has a negative effect on executive compensation, we infer that the increased risk may cause managers to take a conservative policy that induces their salaries decreasing. Not all kinds of Firms’ risks do have an effect on executive compensation in the same direction, so the effects may vary with sources of Firms’ risk. Total asset turnover and days-inventory turnover have a significant impact on executive compensation. The results show that the higher operating efficiency will bring the higher reward for executives. The interaction between Firms’ risk and operational efficiency has a significant impact only on employees’ bonus. In addition, we also consider firms’ scale, the study finds that the relationship among firm risk, operational efficiency and executive compensation is more significant on larger enterprises than smaller ones. We infer that it is because a larger enterprise has sufficient capacity to give managers more compensations.

It has been the goal of the government for years to become more capable and efficient under the administrative reform for the benefits of all citizens. Out of the government’s administrative reform and restructuring, setting up e-government is the one that stands out among other achievements, and within the e-government, the establishment of national household and military registration information system in every Household Registration Office is perhaps the most efficient. This study aims to conduct the analysis of operational efficiency on different levels of Household Registration Offices after their computerization by discussing related papers as theoretical foundation, and tries to set up an assessment mechanism that covers both theory and practicality with a view to bringing up suggestions and recommendations for the assessed units. This study applies “Data Envelopment Analysis” to take samples of Household Registration Offices from every township in Taiwan area, Taipei City, Kaohsiung City and Fu Jian Province. There are total 213 effective Household Registration Office samples in return. Information resources come from the monthly statistical table of household registration cases in each Household Registration Office in December 2004. Input items are personnel expense, capital expenditure and ordinary expenditure; output items are household registration cases, household administration cases and governmental paperwork cases. The evaluation of operational efficiency is through the analysis of overall efficiency, technical efficiency and scale efficiency. The efficiency differences among different levels of Household Registration Office are also compared and improvements are recommended accordingly. The findings of this study are as the following: 1) In respect of overall efficiency, technical efficiency and scale efficiency, Level One Household Registration Office is the most efficient, followed by Level Two Household Registration Office. The efficiency of Level Three Household Registration Office is relatively low. 2) The government’s promotion in implementing computerized household registration and single window service for various applications is rather efficient in terms of resources allocation. For Household Registration Office of different levels, however, there is still room for improvement in terms of the utilization of resources, and an overall examination should be conducted. Certain service measures, activities or seminars, which are meant to be beneficial to the public but are either not cost-efficient or irrelevant to the business, should be discontinued immediately to avoid any waste of the resources. 3) Scale efficiency is not the main factor that causes the overall efficiency to be poor. Level One Household Registration Office with increasing return to scale should be expanded while Level Two and Level Three Household Registration Office may be merged to become one since the increase of input items cannot efficiently produce the increase of output items due to not enough population to serve in the designated area. Based on the conditions of geographic environment and features, those merged units may be transformed into Public Service Stations to increase operational efficiency. Key words: household registration office, data envelopment analysis, operational efficiency

In recent years, internet is an indispensable business resource. The security of network becomes a very important issue. Despite years of experience and experimentation, these firewall protection mechanisms are far from ideal. Due to the rapid changes of network environment, firewall policy rules must be regularly revised for maintaining system function and impring efficiency. Application of data mining techniques to analyze firewall logs can assist companies analyze the merits of the firewall policy table. Enterprise administrators are able to adjust the firewall device rules to enhance operational efficiency. This paper use a corporate firewall logging data to detect frequent characteristic rules through a network of association rules, such as identifying the frequently accessed destination address or blocked ip address. And joining, adjusting or removing rules by using Emerging Patterns, Added Patterns and Perished Patterns of Change mining methods to investigate association rules from two different period of time. Comparing with prior studies, using a analyzed enterprise firewall logging data can help administrators to find much more critical association rules, improve the firewall device efficiency. Compare to asscocitation rules analysis, the results of this study show that combing adjusted rule table through Change mining will effectively reducing the burdens on business administrator. Besides, integrated firewall policy rules can identify some specific unusal accesses of destination address, what’s more to find out the abnormal internal network source address.

Food security issues, such as Plasticizer Scandal and Gutter Oil Scandal, now very frequently erupts in nowadays Taiwan society, which, due to distrust and refusal from the public, not only incur negative effects to a corporation’s reputation, but also severely impact the corporate financial statement to obstruct her sustainable development. Increasingly, it is required that a corporation should take full social responsibilities, and hence the corporate social responsibility (CSR) becomes critical issues of inventive competent advantages as well as sustainable development of the corporate. Accordingly, this research deals with the relationship between CSR and corporate operation efficiency as well as financial performance, in which samples of CSR are adopted from awarded companies between 2005 to 2014 in three credible civil society institutions. This research adopts means of Propensity Score Matching(PSM) and Fix Effect Regression Mode(FERM) to review the sample companies, and the results appear that: (1) CSR appears significant positive correlation to current operational efficiency; (2) CSR appears significant positive correlation to current turnover of assets as well as average turnover of assets in three years; (3) CSR appears positive correlation to current return of assets but not significant; and (4) CSR appears positive correlation to current return of equity but not significant, but appears significant positive correlation to average return of equity in three years. The sensitivity analysis indicates CSR appears significant negative correlation to current net income-Exc Dispo, but the average net income-Exc Dispo in three years of the CSR corporation will present improvement. This research demonstrates CSR corporations may obtain better operation efficiency and turnover of assets than CSR-less corporations. Although the CSR corporations may not improve current corporate financial performance significantly, however they will have significant improvements in long-term turnover of assets and long-term return of equity.
