Abstract:

Introduction: A trend for organisations to change from single to multiple project management has been observed over the last couple of decades. Organizations shifted their focus from single project management towards the simultaneous management of the whole set of projects as one entity – project portfolio. New multi-project settings require a new management approach and practices to successfully manage a portfolio. A common practice in organizations is to evaluate projects after they had been carried out. At that point not much can be done and it is impossible to improve performance and prevent failure. Hence, problems that occur in projects’ implementation phase remain unsolved and even unidentified. Constant control, review and monitoring of projects’ performance in the implementation phase could lead to the problematic portfolio areas being spotted and timely management decisions being made in order to improve the overall portfolio performance.

Problem: How do organisations manage projects within a portfolio that perform poorly in the implementation phase?

Purpose: The purpose of this thesis is: to describe to what extent and in what ways organizations control, review and monitor project performances in the implementation phase; to identify if organisations use any methods, tools or techniques in order to spot projects that perform poorly according to their expectations; and to discover what happens to the poorly performing projects in the implementation phase after they were identified.

Method: An electronic qualitative questionnaire had been constructed and sent out to the 46 sampled Swedish companies currently running project portfolios. 115 most suitable respondents had been chosen to answer the survey.

Frame of Reference: Theoretical framework is built on the literature within project portfolio management field, mostly concerning control, review and monitoring of projects of projects’ performance within their implementation phase; practices used to manage poorly performing projects as well as the value of organizational learning.

Conclusion: The research results show that even though majority of the studied organizations are aware and striving towards efficient project portfolio control, review and monitoring, a lot of space for improvement still remains. Results reveal that organizations are trying to keep track of projects’ performance within a portfolio, however, very few poorly performing are identified. Moreover, the management practices for underperforming projects are still very limited if not non-existent.

Abstract:

Project evaluation is concerned with indicators setting and performance tracking along the life of a project. It plays an essential role to the success of any project and therefore demands special attention. At the heart of this process lies a system of criteria one has to take into account when performing the evaluation. Our thesis considers this problem in a particular context, namely New Service Development (NSD) projects. The topic is of our interest because innovation (hence NSD) has become an inherent aspect of service industry while the research dedicated to NSD project evaluation is rather limited. Our thesis aims at understanding the purposes, the process of evaluating NSD projects and pointing out specific criteria included during the evaluation of NSD projects. As a result, the research question pursuing is: ‘What are key Evaluation Criteria for New Service Development projects?’ From the literature review on project evaluation and new service development, our study reveals a list of eight important criteria of evaluation. This consists of three financial criteria: (1) profitability, (2) production cost, (3) return on investment; and five non-financial criteria: (4) strategic fit, (5) marketing criteria, (6) corporate social responsibilities, (7) information quality, and (8) facilitating factors. From empirical perspective, qualitative approach is applied to collect data through three case studies and a series of semi-structured interviews with seventeen respondents in Albania, Italy, Sweden and Vietnam, from companies offering various types of service. The case studies build comprehensive understanding on the process of new service development, of project evaluation for NSD whereas interviews check the transferability of the three cases and identify evaluation criteria employed in practice. The empirical results were analyzed in comparison with the arguments found from literature. Regarding the research question, the study found that the set of evaluation criteria collected from empirical study fits with the list of eight criteria proposed by literature. Among this set, two main criteria ‘strategic fit’ (4) and ‘customer satisfaction’ which is apart of ‘marketing criteria’ (5) are recommended as ‘must’ for the evaluation process on any type of NSD project. Findings of this research contribute to the existing knowledge provided by both academic and practitioners regarding both project management field and new service development area, by suggesting a set of key criteria that should be used as guidance in order to succeed with evaluation of NSD projects.

Abstract:
Upravljanje promenama u projektu je nova i specijalizovana menadžment disciplina koja je malo izučavana u svetu a posebno u našoj zemlji. Predmet izučavanja ove discipline jeste upravljanje složenim naučnim, tehničkim, građevinskim, energetskim, finansijskim i organizacionim projektima koji se realizuju u okolini podložnoj uticaju velikih i brzih promena. Težište rada je usmereno na definisanje koncepta upravljanja promenama, koje mogu biti rezultat uticaja iz okruženja ili promena na samom projektu tokom njegove realizacije. Osnovni cilj upravljanja projektom jeste efikasna realizacija projekta u planiranom vremenu i sa planiranim troškovima u uslovima značajnih eksternih i internih promena. Upravljanje promenama na projektu podrazumeva definisanje takve organizacuione forme koja će omogućiti blagovremeno uočavanje i klasifikaciju relevantnih promena koje mogu nastati u projektu, primenom raspoloživih metoda i resursa u ostvarivanju osnovnih ciljeva projekta. Uzroci promena u projektu proizilaze iz neravnoteže između projekta i okoline ili neravnoteže unutar samog projekta. Upravljanje promenama u projektu odvija se kroz pocese planiranja, uvodjenja i kontrole. U radu je prikazan jedinstven model za upravljanje promenama u projektu koji se uz manje korekcije može primeniti u realizaciji ma kog projekta. Posebnost rada ogleda se u prikazu promena koje su u toku ili koje mogu nastati tokom restruktuiranja elektroprivrednog sistema Srbije.
Change management in project is a new and specialized management discipline that have been studied a little in the world, particularly in our country. The subject of research of this discipline is managing of a complex scientific, technical, civil engineering, energy, financial and organizational projects that are realized in the surrounding liable to the influence of a big and fast changes. The centre of work is directed towards the defining of concept of change management, that can be the result of the surrounding influence or the changes of the project during its realization. The basic aim of project management is an effective project realization in the planned time and expences in the conditions of important external and internal changes. Change management on the project means defining of such organizational form that provides timely observation and classification of relevat change that can appear in the project, applying the avaible methods and resource in the realization of the basic project aims. The causes of project changes appears from the disbalance between the project and surrounding or disbalance in the project itself. Change project management have been done through the processes of planning, introducting and control. The unique model for change management in project is presented in the paper that can be applied with a little changes in realization of any other project. The individuality office work is prezented in the description of changes that are under way or that can appear during the reconstruction of the power plant system in Serbia.

Abstract:
Metric collection process and Project Management activities cannot be performed in an integrated fashion on most of the software projects. In software engineering world, there are Project Management Tools that has embedded project metrics and there are various Metric Collection Tools that collect specific metrics for satisfying requirements of different software life cycle phase activities (Configuration Management, Requirements Management, Application Development tools etc.). These tools however are not communicating with each other with any interface or any common database. This thesis focuses on the development of a tool to define, export, collect and use metrics for software project planning, tracking and oversight processes. To satisfy these objectives, POMMES with functionalities of Generic Metric Definition, Collection, Analysis, and Import, Update and Export of Project Metrics from 3rd Party Project Management Tools is developed and implemented in a software organization during this thesis work.

Abstract:
Purpose – This research aims to explore the effectiveness of utilising Benefits Realisation Management (BRM) as part of comprehensive success measures, emphasising the stage in-between appraisal and evaluation of projects in the UK public sector. Design/methodology/approach – The study is constructed as a qualitative case study. Semi-structured interviews are used as part of the inductive, exploratory approach to achieve the study's objectives. It employs an approach based on grounded theory for its analysis. Findings – This paper suggests that Benefits Realisation Management is not used effectively in the UK public sector during projects lifetime to control and monitor projects and ensure their success. The current reviews of projects and programmes, through their execution, may not be sufficient. Research limitations/implications – This study offers contributions to the project success literature and benefits management literature by adding empirically supported insights about BM utilisation during project reviews. The research may be limited primarily by the research method – predominantly the snow-balling data collection. The assumptions made about the UK public sector may limit the broader generalisation of the findings. Practical implications – This research may be used to advise the practising managers of the need to maintain benefits orientation after appraisal throughout a project's lifetime and after delivery. Project governance structures are advised to update and improve their current project review practices. The study additionally identifies possible obstacles to the process and biases. Originality/value – This paper attempts to fill a literature gap by providing empirical results that explore the success definition and measures and the effectiveness of BRM during project execution and gate reviews.

Full text
Abstract:
Existing literature and research findings indicated that cost monitoring and control of construction projects by contractors at the level of site operations has remained ineffective largely due to inability of existing control systems to accurately predict when, to what extent and why an on-going operation or project is to overrun its planned duration and cost. In most cases the information that would enable such advance detection becomes available to decision makers after the affected operation or project is completed. It is then hoped that the information could be used to 'control' future similar situations which in the case of construction projects hardly arise, at least never under identical circumstances. The existing cost control systems also fail to enable rational corrective decisions to be formulated. This resulted in total reliance on previous experience and personal intuition to make a guess of corrective measures. Most research efforts have focussed mainly on various aspects of project modelling and cost control using traditional accounting approaches that consistently fail to meet the requirements and schedule of timely cost control. This research identified, from empirical evidence, construction and management science literature, the essential criteria and features of an effective cost monitoring and control approach for construction projects. The evidence from these three sources led to the formulation of an alternative approach based on quantitative analysis of cost data from construction projects. The cost monitoring and control process carried out on sites was formulated as a problem whose solution process is implemented using multiple regression and goal programming models and techniques that enable timely evaluation and prediction of costs and a rational computation of corrective decisions. This allowed cost deviations to be detected and optimum corrective measures calculated while the affected operation or project was still in progress.

Abstract:
La presente tesi nasce come lavoro redatto in seguito a un periodo di stage svolto presso l’azienda Rosetti Marino SpA. L’obiettivo che si prefigge questo elaborato è quello di descrivere ed analizzare le tecniche di Project Management (in particolare il Planning e il Progress Monitoring) applicate dall’azienda nella realizzazione dei propri progetti. Il Project Management è definito come l’applicazione alle attività di un progetto delle conoscenze e tecniche per raggiungere i requisiti progettuali di tempo, costo, qualità e scopo, e viene adottato frequentemente dalle aziende per la gestione di progetti interni ed esterni. Se un’azienda vuole crescere nell’attuale contesto competitivo deve essere capace di innovare e innovarsi: il Project Management permette di innovare attraverso il miglioramento delle performance di impresa. L'elaborato si concentra sull’applicazione del Project Management nelle società EPC, ovvero società che assumono il ruolo di General Contractor nel fornire a terzi servizi integrati di Engineering, Procurement and Construction. Nello sviluppo della tesi viene fornita una panoramica delle tecniche e conoscenze necessarie. Si inizia da un approfondimento delle caratteristiche del Project Management e delle teorie che sono alla base della sua versatilità di applicazione. Si prosegue con l’introduzione del concetto di business EPC e delle sue peculiarità. Si arriva infine alla declinazione di quanto visto nelle sezioni precedenti all’interno dell’azienda Rosetti Marino, leader in Ingegneria e Costruzioni nel settore Energy (Oil & Gas). In questa sezione ci si concentra sull’analisi degli strumenti adottati durante le fasi di pianificazione e controllo dell’avanzamento del Tyra Redevelopment Project a cui Rosetti Marino ha preso parte come Contractor EPC per la realizzazione del Living Quarter TEH, destinato al complesso offshore di produzione di gas naturale Tyra East situato nel tratto di Mare del Nord appartenente alla Danimarca.

Abstract:
The growing demand for hydrocarbon fluids, and the future expectation of insufficient onshore reserves, is driving the exploration and development of off-shore oil and gas fields. A significantly increasing number of the new fields are situated in deep water, placing significant constraints on the application of conventional platform (sea surface) systems. This has, by necessity, generated the rapid growth of sub-sea processing technology.
An integral part of a novel sub-sea natural gas dehydration project is the need to design and develop a communications, monitor and control system that is extremely reliable within a harsh marine environment. The off shore gas gathering and processing facility will be unmanned, therefore the entire ongoing operation of the sub-sea facility, and any sea surface equipment, will be dependent on the proper functioning of the communication system. System redundancy and low power consumption are also important issues.
The continuous bi-directional transmission of information between the field and shore-based control centres, together with the complexity of any maintenance / repair missions requires an extremely highly reliable system. The prospect of false alarms must be maintained at an absolute minimum.
Within this thesis the history and development of ocean based communications up to current state-of-the art technology is reviewed. Based on the unique and demanding requirements of the sub-sea gas processing facility, detailed recommendations are made for both a primary and back-up communication systems that meet the given criteria of being robust and having very low power requirements.

The monitoring systems that are currently used as part of the management of construction projects consist of collecting the field information, documenting it manually and then digitizing it. Those responsible for carrying out the reports through this procedure dedicate between 28% and 41% of their time daily for their preparation. This traditional process is slow and inefficient because the information is dispersed in different documents, so data can be omitted, causing that no corrective actions are taken in a timely manner. Likewise, the construction sector has little use of technological resources, and therefore, there is no automated process, which makes it difficult to monitor construction projects in an efficient way. In this sense, this research establishes the optimization of the control procedure through the use of a data acquisition tool to reduce the man-hours used in advance control. With the application of this proposal, the hours spent by the personnel involved in project management were reduced by 30%.

Abstract:
Grenada is 1 of 15 developing countries in Caribbean Community known as CARICOM. The infrastructure capital projects in these developing countries are plagued with an array of issues: unethical practices, inadequate supervision, lack of transparency and accountability, inadequate monitoring and evaluation, cost overruns, and inefficiencies. In the 1980s and 1990s, the International Monitory Fund and World Bank introduced a balanced scorecard engineered under the structural adjustment program, but it was unable to improve infrastructure project efficiencies. This qualitative case study sought to understand the role of management key performance indicators (KPIs) on public sector infrastructure capital project efficiency on the island of Grenada. An institutional assessment and development framework and a classical management theoretical framework methodology were used to explore the effects of management KPIs on public sector infrastructure capital projects efficiencies in developing countries. The research incorporated a constructivist philosophy that underpins the evaluation and perception of the government, the National Water and Sewerage Authority (NAWASA), project teams, systems, and stakeholders. A purposive sampling strategy with elements of snowballing was used to obtain 12 representative participants for interviews, and a systematic approach of transcribing, coding, and thematic analysis was done. Findings indicate inadequacies in the BSC performance measure system on infrastructure projects, which justifies the use of comprehensive management KPIs. Positive social change implications of this study include recommendations for comprehensive management KPIs and policies to improve public sector infrastructure project efficiency in Grenada.

A realização de projetos pelas organizações é uma prática amplamente utilizada para obter resultados diferenciados. No entanto, a insatisfação com os resultados obtidos não é uma exceção. Entre os fatores que influenciam o desempenho dos projetos está a execução eficiente e eficaz dos processos relacionados ao monitoramento e controle do projeto. O uso de Tecnologias da Informação Móveis e Sem fio (TIMS) podem contribuir na execução de processos nos quais os trabalhadores possuem características de mobilidade. O objetivo deste trabalho é investigar de que formas a utilização de TIMS nos processos de monitoramento e controle do projeto afeta o desempenho do mesmo. A metodologia empregada para alcançar esse objetivo foi baseada na realização de uma etapa exploratória, na qual se entrevistou gerentes de projetos para compreender melhor o fenômeno. Com base nas percepções dos entrevistados e na revisão teórica sobre gestão de projetos e TIMS foi proposto um modelo conceitual que demonstra a relação entre o grau de utilização de TIMS nos processos de monitoramento e controle do projeto e o desempenho dos projetos. Uma survey foi realizada com gerentes de projetos para verificação empírica do modelo, tendo ao final uma amostra de 223 respondentes. Como técnica estatística utilizou-se a Partial Least Squares(PLS). Nos testes de validação do modelo foi necessário retirar o constructo dependência da localização. Na análise dos resultados observou-se que a relação entre a criticidade do tempo e o uso de TIMS não possui, no contexto da pesquisa, significância estatística. Por outro lado, o constructo mobilidade possui uma relação estatisticamente significativa com o uso de TIMS. Da mesma forma, o uso de TIMS nos processos de monitoramento e controle do projeto possui relação significativa estatisticamente com o desempenho de projeto. Os resultados obtidos indicam uma relação positiva entre o uso de TIMS nos processos de monitoramento e controle e o desempenho do projeto, especialmente em relação ao cumprimento do prazo. Como limitações da pesquisa destaque-se a forma de medição da mobilidade do gerente de projetos e a verificação do uso de TIMS apenas nos processos de monitoramento e controle dos projetos. Sugere-se para futuras pesquisas o aprimoramento da forma de medir a mobilidade dos gerentes de projetos e a inclusão da análise do uso de TIMS em outros processos relacionados ao gerenciamento de projetos que podem afetar o desempenho dos projetos.
ABSTRACT The development of projects by organizations is a widely used practice to get different results. However, dissatisfaction with the results obtained is not an exception. Among the factors influencing project performance is the efficient and effective implementation of processes related to monitoring and controlling the project. The use of mobile technologies can contribute to the execution of processes in which workers have mobility characteristics. The objective of this study is to investigate ways that the use of mobile technologies in project monitoring and controlling processes affects project performance. The methodology used to achieve this objective was based on the realization of an exploratory stage in which we interviewed project managers to better understand the phenomenon. A conceptual model that demonstrates the relationship between the degree of use of mobile technologies in the project monitoring and controlling processes and projects performance was proposed. It was based on respondents' perceptions and theoretical review of project management and mobile technologies. A survey was conducted with project managers for empirical verification of the model. At the end of the survey sample consisted of 223 respondents. We used the statistical technique of Partial Least Squares (PLS). During validation of the model it was necessary to remove the construct dependence on location. The analysis of the results showed that the relation between the critical time and the use of mobile technologies is not of statistical significance in the context of research. Moreover, the mobility construct has a statistically significant relationship with the use of mobile technologies. Likewise, the use of mobile technologies in project monitoring and controlling processes has statistically significant relationship with project performance. The results indicate a positive relationship between the use of TIMS in project monitoring and controlling processes and project performance, particularly with respect to time. We highlighted the limitations of the survey method of measuring the mobility of the project manager and the verification of the use of mobile technologies just in project monitoring and control processes. We suggest for future research the improvement of the method of measuring the mobility of project managers and the inclusion of the analysis of the use of mobile technologies in other processes related to project management that may affect project performance.

Abstract:
Project control systems often fail to support management in achieving their global project goals. This thesis proposes a Multidimensional Project Control System (MPCS) as an approach for quantifying deviations from the planning phase to the execution phase with respect to the global project control specification (GPCS). The projects' current state must be translated into yield terms, which are expressed as a gap vector that represents the multidimensional deviation from the global project control specification. The MPCS methodology allows the project manager to determine: integrated project status; where problems exist in the project; when and where to take corrective action; and how to measure improvement. However, implementing the MPCS methodology does not require extra data collation. MPCS deals with the control of a single project and defines the project performances in comparison with the plan. The progression of several projects in parallel is a common situation in organizations, therefore a comparison of the various project performances is required. It is proposed that a comparison process be performed using the data envelope analysis (DEA) approach. The reference points for examining the performances of different projects and the directions of improvement for the projects are not necessarily found on the efficiency frontier. An algorithm is developed for applying multi-project system control having a relatively large number of inputs and outputs while maintaining the validity of the DEA methodology. The DEA output allows the diagnosis of those found on the efficiency frontier and those that need improvement.

Abstract:
This thesis is about software project scheduling and use of earned value method on software projects. As a result of the study, a solution for software project scheduling problems is proposed. A mathematical formulation, developed using integer programming method, is at the heart of the solution. Objective of the formulation is to minimize the development costs consisting of direct labor cost, indirect costs and probable penalty costs. The formulation takes the capability and compatibility variances among resources into account whereas contemporary approaches mostly focus on resource availability. Formulation is of type discrete time and takes the time span to be searched as input. Therefore a heuristic approach has been developed for providing time span input to the models developed using the formulation. The heuristic approach has been proven to be calculating a time span that does not hinder achieving the absolute optimum schedule and shortens the solution time of the integer programs. The heuristic approach and problem formulation have been incorporated into a computer program that generates integer programs and heuristic solutions. This thesis also describes a method for preparing an earned value plan, based on the scheduling solution defined. The method aims to help project managers in determining the status of their projects and deciding whether any corrective action is required or not. Besides the method, approaches for incorporating indirect costs and penalty costs, which are not explicitly discussed in literature, into final cost estimation have been described.

Abstract:
The purpose of the SCRIT project is to determine size and shape of short-lived and rarely-produced nuclei by elastic electron scattering, which is the best probe for the structure studies, for the first time. In traditional electron scattering, a solid target having an order of 1023 nuclei/cm^2 is normally used, which is not possible for short-lived and rarely-produced nuclei. In this project a Self Containing Radioactive Isotope Target scheme (SCRIT) is going to be employed. This innovative ion-trap method is shown to be a way to make measurements with a very small amount of nuclei, an order of only 106 nuclei. In order to determine the absolute cross section for elastic electron scattering for structure study, the simulates measurement of the bremsstrahlung from the trapped nuclei is required. Since the bremsstrahlung cross section for a nucleus of the atomic number Z is well know, the precise measurement of the bremsstrahlung provides the luminosity. My theme in this SCRIT project was a construction of a bremsstrahlung luminosity monitor. It consists of a position monitor for measuring the spatial distribution of bremsstrahlung and a Pb-glass Cerenkov detector for energy measurement. My efforts have been mainly devoted to the construction of a position monitor system using fiber scintillators. The construction of the position monitor was divided into five parts; detector construction, support construction, trigger detector construction, software programming, software testing and detector tests. The position monitor consists of two sets of fiber scintillation detectors. Each of them uses 16 fibers, Bicron BCF-10 with a cross section of 2x2mm^2, optically coupled to a multi-anode photomultiplier, (Hamamatsu H6568-10). The position monitor can measure the XY distribution of bremsstrahlung. Strictly speaking, the fiber detector detects not bremsstrahlung directly but electrons and/or positrons by pair creation of bremsstrahlung in a materials. The data acquisition system has been programmed in NI LabVIEW. The software is an advanced X/Y-coordinate counting system, which can additionally preform functions as save data to file and 3D-plot to determine the spreading of the bremsstrahlung luminosity. The results can be saved and transferred online to a server so that is possible to access the data from anywhere. The system has been tested using beta rays from 90Sr source. The results of the test shown that the detectors can detect minimum ionizing particle, i.e. electrons and positrons. The detector and software testings shows that the system is ready to use for luminosity measurements at SCRIT experiment. This system I constructed surely provides a new and useful information for the SCRIT experiments.

Abstract:

Information is power; when we know something, it is hard to ignore. The foundation of this thesis is to create awareness about the inadequacy of the existing project control and management system (PCMS). There is a need for rapid improvements in PCMS, and proposed actual improvements in PCMS are put forward here. Patty and Denton said, “If there is anything to be learned from the history of work-process innovation, it is that any system of principles and methods will experience a life cycle. In other words, as processes mature, innovation is required to facilitate survival, let alone growth in sales of any product or service” (Patty and Denton 2010). The PCMS for capital project delivery in the engineering procurement construction (EPC) industry is in the same situation; it has completed its cycle and is in need of innovation. This thesis describes: “What Is”, the current state of Project Control and Management System (PCMS); “What Should Be”, the practices of PCMS: and “How to Close the Gap”. The advancements in PCMS are based on concepts which are process derived from Lean concepts and principles already applied in other industries such as manufacturing, aerospace, and ship building, where they have exhibited tremendous benefits. A new classification of PCMS is explained based on its characteristics and objectives. Two models are proposed to enhance the PCMS and make it a Lean PCMS. A “Real Time Visual Control Flow System Model” is proposed to enhance the existing flow system beyond advanced work packaging and the last planner system, by incorporating aligned breakdown structure, pull planning and control, real-time control, visual control, critical chain project management, making and keeping commitments. Our “Lean PCMS” model is proposed to enhance the whole system of PCMS and achieve the desired state of excellence for PCMS. The intention of this research is to make the current PCMS a Lean PCMS and to shift the reactive approach of project controls to a more proactive approach. A case study, “How to Close the Gap”, using Kaizen methodology (only the Kaizen appraisal stage, in real settings) in a large EPC (Engineering, Procurement, and Construction) company, is described.

Abstract:
In this paper, a computer vision system for counting people standing in line is presented. In this application, common techniques such as Adaptive Background Subtraction (ABS), blob tracking with Kalman filter, and occlusion resistive techniques are used to detect and track people. Additionally, a novel method using Dual Adaptive Background Subtractors (DABS) is implemented for dynamically determining the line region in a real-world crowded scene, and also as an alternative target acquisition to regular ABS. The DABS technique acts as a temporal bandpass filter for motion, helping identify people standing in line while in the presence of other moving people. This is achieved by using two ABS with different temporal adaptiveness. Unlike other computer vision papers which perform tests in highly controlled environments, the DABS technique is tested in a crowded Starbucks© at the Cal Poly student union. For any length of people standing in line, result shows that DABS has a lower mean error by one or more people when compared to ABS. Even in challenging crowded scenes where the line can reach 19 people in length, DABS achieves a Normalized RMS Error of 43%.

Full text
Abstract:
When executing a plan, the traditional assumption of complete certainty is rarely valid; in real-world situations, actions may fail to complete, or may take much longer than initially anticipated. Because of this, layers of robustness are required that allow flexibility during execution. There are two aspects of an executive that need addressing to provide the ability to deal with uncertainties: monitoring and control. This thesis examines both of these aspects and shows how these may be used during execution. For monitoring, the use of Hidden Markov Models is proposed. Tracing the execution of a task through a model allows the executive to detect its current state, even when this is not directly observable from within the system. The trajectory of states through the model can reveal execution irregularities, which can be flagged and identified as failure. This work explores the use of learnt models, evaluating their performance in various contexts. For control, the use of opportunistic plans is examined. These can be used after failure has occurred, or when an action successfully finishes early. The definition of opportunistic plans is expanded to include extra structures that may be of use during the creation of these. Execution issues surrounding opportunistic plans are addressed, including how to decide when to execute an opportunity. The logical requirements for this are discussed, and several opportunity insertion strategies are developed. This is followed by a technique for deciding if resources should be conserved for later opportunities with the prospect of greater reward.

Abstract:
The present Computer Numerical Controlled (CNC) machine tools can provide internal states of the machine (such as speed, feed, current, power, torque, and axis tracking errors) to external computers, which in turn can manipulate spindle speeds and feeds through Ethernet communication tools. This thesis presents on-line detection and avoidance of chatter vibrations, on-line prediction of cutting torque and its adaptive control during milling operations. Chatter is detected by monitoring the frequency spectrum of sound signals during machining operations. The forced vibrations that occur at spindle and tooth passing frequencies are removed through a comb filter. The chatter frequency and its magnitude are predicted. The spindle speed is automatically changed to enter the process into the nearest stability pocket if it lies within the first five stability lobes. If the process cannot be stabilized due to missing lobes at low speeds, the spindle speed is harmonically varied without violating the power limit of the spindle drive. The algorithm is implemented on a five axis Mori Seiki NMV5000 Machining Center with a FANUC 30i controller. The communication with an external PC is handled through Ethernet and FOCAS command library of Fanuc. The cutting torque is also predicted by monitoring the current of a three phase induction motor in real time. The cutting torque is estimated through Extended Kalman Filter from the steady state model of the motor after removing the friction component. The estimated torque is used to keep the cutting torque on the machine at desired and safe levels by manipulating the feed rate with adaptive pole placement controller. The thesis shows that it is possible to add process monitoring and control functions to the machine without having to add costly and impractical sensors on the machine, leading to safer and more productive machining operations.

Abstract:
Powerful access control is becoming one of the major needs in scientific project management systems these days. Because the requirements are becoming more and more sophisticated and highly discipline specific, no existing access control tool is available that developers could adopt directly. This thesis proposes a general and flexible security administration module that can be easily integrated into scientific project management systems, especially if they are based on a 3-tier architecture. The module is based on role-based access control (RBAC) technology to provide flexibility and extensibility. In order to control access on the level of individual table tuples, a new concept, named condition, is introduced. Aspect-oriented programming (AOP) technology is adopted to integrate the access control component into the 3-tier framework. A concrete implementation is performed on the prototype project management system Exp-DB using AspectJ.

Abstract:
Abstract. In today’s technologically advanced world, projects are becoming much more complex and managers often face challenges of controlling the pace of the project. Visual project management is a fundamental element of lean methods that allows the project management activities to accomplish efficiently and effectively within the timeline. The challenges and complexity of projects are on the rise nowadays due to distinct unpredicted characteristics for instance workplace accidents, environmental effects, price hiking of materials cost and so on. Lack of controlling and monitoring the external or internal events within the project sometimes drive to project failure. This thesis aims to gain an insight into the visual project management practices in various projects through literature analysis along with the understanding of the contribution of visual tools and elements in the purpose of controlling the project. The initial part of this research focuses on in-depth literature review concerning the functions, tools, elements and the current state of the visual project management. The analysis is conducted by keeping two case studies as examples. The literature review reveals the contribution of visual management to support managerial strategy by integrating information, providing the elements, tools, and sensory aids into various project work settings. Following this, a qualitative analysis of two case projects provides the insight into the findings of this thesis which focuses on the prominence of visual management in two different project characteristics. Through the analysis and discussion, the anticipation of visual management was explored and identify the findings that disagree or complements the previous literature. Nevertheless, the overall research is concerned with the improvement of the project performance and effectiveness, removing potential threats and uncertainties and controlling the project through visual project management philosophies.

Abstract:
The exchange rate market has traditionally played a key role in the financial market. The variation of the exchange rate which is called volatility is also an important feature for studying the exchange rate market because the increased volatility may have a negative effect on a nation's economy by increasing the uncertainty in the exchange market. In this paper the volatility of the exchange rate is considered by means of a Heterogeneous Autoregression Conditional Heteroskedastictity (HARCH) Model. It explains the volatility of the exchange rate market well. In addition, it is assumed that at a random time point a change of a parameter in the distribution of the random process underobservation may occur. Some methods such as the Shewhart method, the Culumative Sum Method (CUSUM) and the ExponentiallyWeighted Moving Average Method (EWMA) are investigated within the frames of this change-point problem. In order to evaluate them, Average Run Length (ARL) and Conditional Expected Delay (CED) will be used asperformance measures.

Abstract:
This report describes a project undertaken to monitor and control the different air states in an air conditioning plant. From previous equipment purchases and development work, the Department of Mechanical Engineering in Canterbury University has a Hilton® A770 air conditioning rig for demonstrating the basic psychrometric processes, and an environmental control chamber for providing any particular 'outside' air state. In this project a model ‘building’ has been installed inside the environmental chamber to simulate an inside air-state of a building and, has been interconnected to the Hilton rig to supply and condition the air (to the model building) as required. The supplied air state to the model building is controlled by means of the different air conditioning components installed in the Hilton rig such as a preheater, steam generator, refrigerated cooling coil, and a reheater. In turn, the Hilton rig has been modified to use a controlled air state, drawn from the environmental chamber, to simulate winter, summer or any other supply state to the model which is acting as a space load for the Hilton rig. Data acquisition electronics such as sensors, multiplexers and signal conditioners have been installed in the system to manipulate the large amounts of data on real time. Provision of real time display of the values being measured is updated after each sample through a software program written for Windows95®, with a 3-D graphical user interface and other many enhancements. An important feature of this software is that the different air conditioning processes can be displayed on a linked on-screen psychrometric chart developed in the Department of Mechanical Engineering, which can be printed out. Overall, the facility represents, on a much-reduced scale, a building and its air conditioning system operating within an artificially created and controlled outdoor environment. And, using a personal computer, psychrometric conditions are monitored and controlled; the energy transfers are verified; and the different processes are displayed on a psychrometric chart.

Abstract:
The thesis presents several aspects related to the industrial and academic activities associated with monitoring and control of the machining process and machine tools. A survey of the industrial situation identified some key factors for a successful implementation of monitoring and control techniques. Applicable, relatively simple, systems for cutting-process monitoring and adaptive control are available on the commercial market today but the degree of industrial utilisation of the technique is low because the systems are experienced as hard to operate and use, and are at the same time considered unreliable. In order to promote a higher degree of industrial utilisation more work has to be devoted raising the performance of the system solutions. An Integrated Supervisory Process Control (ISPC) concept is presented as an approach dealing with multi-purpose control requirements utilising the individual advantages of several sensors and modelling techniques. The ISPC system is supposed to operate as a conceptual integration of sensors, process models and different control modules. Two prototype systems, based on five-axis machining centres, for real-time control of the machining process are outlined. Different strategies for monitoring and control are developed, implemented and experimentally tried out, and the studies conducted demonstrate results that encourage further research work devoted to verification of the proposed control concept. The results obtained in the initial experiments utilising methods for process control and monitoring, such as double exponential smoothing technique (DES), multivariate monitoring applied to signal tracking and artificial neural networks applied to cutting torque control, reveal that the different techniques have potential to improve the performance of monitoring and control tasks, thus contributing to the creation of more sophisticated and reliable solutions in the ISPC concept.

Abstract:
During the summer excess energy is produced from solar heaters, this is not taken care of, and usually goes to waste. The base of the project is built on that you should take the excess energy during the warmest months of the summer and save the energy in boreholes in the ground, then during the colder months the energy can be used. The purpose of the project was to build a prototype for the control and monitoring of a system. With this project we want to present a solution to a prototype which can be used as a development platform for the client. Communication between the actuators, sensors and the controller is made via a CAN-bus. The temperature sensors uses a One-wire buss and its values are stored and can be shown on a website. The results show that the monitoring and control functions works. Theoretically, the prototype is designed to be expanded to a real application.
Under sommaren produceras överbliven energi från solvärmare, denna tas inte omhand utan går oftast till spillo. Projektets grund bygger på att ta den överblivna energin under de varmaste månaderna på sommaren och spara undan energin i borrhål i marken, för att sedan under kallare månader kunna använda detta. Syftet med projektet har varit att bygga en prototyp för styrning och övervakning av ett system. Med detta projekt vill vi visa en lösning på en prototyp som kan fungera som utvecklingsplattform för beställaren. Kommunikation mellan aktuatorer, sensorer och styrenhet görs via en CAN-buss. Temperaturensorernas använder sig av en One-wire buss och dess värden sparas och kan avläsas på en webbplats. Resultatet visar att övervakning av sensordata och reglering av aktuatorer fungerar. Teoretiskt sett är prototypen utformad för att expanderas till en verklig applikation.

Abstract:
Thesis (Ph. D.)--Boston University
Persistent monitoring tasks arise when agents must monitor a dynamically changing environment which cannot be fully covered by a stationary team of available agents. It differs from traditional coverage tasks due to the perpetual need to cover a changing environment, i.e., all areas of the mission space must be visited infinitely often. This dissertation presents an optimal control framework for persistent monitoring problems where the objective is to control the movement of multiple cooperating agents to minimize an uncertainty metric in a given mission space. In an one-dimensional mission space, it is shown that the optimal solution is for each agent to move at maximal speed from one switching point to the next, possibly waiting some time at each point before reversing its direction. Thus, the solution is reduced to a simpler parametric optimization problem: determining a sequence of switching locations and associated waiting times at these switching points for each agent. This amounts to a hybrid system which is analyzed using Infinitesimal Perturbation Analysis (IPA) , to obtain a complete on-line solution through a gradient-based algorithm. IPA is a method used to provide unbiased gradient estimates of performance metrics with respect to various controllable parameters in Discrete Event Systems (DES) as well as in Hybrid Systems (HS). It is also shown that the solution is robust with respect to the uncertainty model used, i.e., IPA provides an unbiased estimate of the gradient without any detailed knowledge of how uncertainty affects the mission space. In a two-dimensional mission space, such simple solutions can no longer be derived. An alternative is to optimally assign each agent a linear trajectory, motivated by the one dimensional analysis. It is proved, however, that elliptical trajectories outperform linear ones. With this motivation, the dissertation formulates a parametric optimization problem to determine such trajectories. It is again shown that the problem can be solved using IPA to obtain performance gradients on line and obtain a complete and scalable solution. Since the solutions obtained are generally locally optimal, a stochastic comparison algorithm is incorporated for deriving globally optimal elliptical trajectories. The dissertation also approaches the problem by representing an agent trajectory in terms of general function families characterized by a set of parameters to be optimized. The approach is applied to the family of Lissajous functions as well as a Fourier series representation of an agent trajectory. Numerical examples indicate that this scalable approach provides solutions that are near optimal relative to those obtained through a computationally intensive two point boundary value problem (TPBVP) solver. In the end, the problem is tackled using centralized and decentralized Receding Horizon Control (RHC) algorithms, which dynamically determine the control for agents by solving a sequence of optimization problems over a planning horizon and executing them over a shorter action horizon.

Abstract:
The generalized likelihood ratio (GLR) control charts are studied for monitoring a process proportion of defective or nonconforming items. The type of process change considered is an abrupt sustained increase in the process proportion, which implies deterioration of the process quality. The objective is to effectively detect a wide range of shift sizes. For the first part of this research, we assume samples are collected using rational subgrouping with sample size n>1, and the binomial GLR statistic is constructed based on a moving window of past sample statistics that follow a binomial distribution. Steady state performance is evaluated for the binomial GLR chart and the other widely used binomial charts. We find that in terms of the overall performance, the binomial GLR chart is at least as good as the other charts. In addition, since it has only two charting parameters that both can be easily obtained based on the approach we propose, less effort is required to design the binomial GLR chart for practical applications. The second part of this research develops a Bernoulli GLR chart to monitor processes based on the continuous inspection, in which case samples of size n=1 are observed. A constant upper bound is imposed on the estimate of the process shift, preventing the corresponding Bernoulli GLR statistic from being undefined. Performance comparisons between the Bernoulli GLR chart and the other charts show that the Bernoulli GLR chart has better overall performance than its competitors, especially for detecting small shifts.

Power systems are typically complex and can be affected by their environment in ways that cannot be completely predicted by their designers. It is thus imperative that monitoring is considered as part of the design of new power systems. Due to the associated costs of maintenance, repair, and downtime, monitoring these systems is particularly important when the installations are remote. Remote locations benefit greatly from renewable energy sources. As a result, this work focuses on a novel Hybrid Inverter system developed by Optimal Power Solutions Pty. Ltd. (OPS). This system uses renewable energy sources, grid power, and diesel generators together with a bi-directional inverter to supply a remote location with grid-quality power.

Abstract:
Recent development in wireless communication technology offer new opportunities for wireless connectivity of field devices in industries such as oil and gas, chemical processing and water distribution. Wireless communications can assist these industries to improve plant knowledge by acquiring additional measurements from processes and equipment when wired communication would be infeasible. Requirements for a field communication network in the process industry include real-time support for mixed traffic, robustness, availability, security, reliability and scalability in a harsh industrial environment. Furthermore, to build such a network on license-exempt band raises concerns relating to its safety, security, performance and governance. Three specific issues have been addressed in this thesis. The first issue investigated is time synchronization which is necessary to ensure data integrity and determinism in network operations. The second investigation is the study of the performance of a closed-loop control application running over a resource-constrained wireless network. The need to ensure co-existence with the other wireless networks operating over the same radio band while offering predictability and reliability has added a new concern to the use of wireless technology in networked control systems. The third issue is to ensure longevity of wireless field nodes operated on standalone batteries which requires a mechanism to minimize energy consumption. This topic was addressed in an investigation into methods for transmission power control. The research presented in this thesis has discovered new ways to solve these problems. It has characterized their performance and implemented them in several practical demonstrations, including one field deployment. The thesis also provides an insight into the opportunities which wireless technology offers, the challenges which it encompasses, and gives a review of key emerging wireless networking technologies relevant to process automation. Finally, it offers an opinion about the future directions of wireless communications in the process industries.

Abstract:
Termisk energi som solfångare producerar kan lagras i Borehole Thermal Energy Storage, BTES, när efterfrågan är låg, för att sedan användas när efterfrågan är hög. Målet med detta examensarbete är att utveckla en skalbar systemarkitektur för styrning och monitorering av en BTES prototyp, där ringarna som borrhålen utgör är indelade i olika temperaturhierarkier. De ringar som ligger närmare centrum av borrhålen har högre temperaturhierarki än de som ligger längre ut. Driftinformation från systemet ska kunna följas på en webbplats och temperaturdata från systemet ska sparas undan för lagring. Datakommunikationen består av en One-Wire buss som innehåller temperatursensorer och ett CAN-buss system för datakommunikation mellan sensor/aktuator-noder och server-nod. Utifrån sensordata bestäms reglering av ventiler. Driftinformation lagras i en databas och från denna databas presenteras informationen på en hemsida. Hemsidan innehåller en överblick av brunnparken där temperaturen i varje brunn kan utläsas. Regleralgoritmen uppfyller den sökta temperaturhierarkin där de högsta temperaturerna ska vara i centrum av brunnparken. Prototypen fungerar som en utvecklingsplattform och demonstrerande prototyp.
Thermal energy produced from solar collectors can be stored in Borehole Thermal Energy Storage, BTES, when demand is low for later usage when demand is high. The aim of this thesis is to develop a scalable system architecture for control and monitoring of a BTES prototype.The BTES prototype consist of 13 boreholes configured in a hierarchically manner in two circles and one core. The core is of the highest priority. The operational information is displayed on a website and stored in a database.The data communication consist of two One-wire buses and one CAN bus. The temperature sensors are connected to the One-Wire buses. The CAN bus consist of sensor/actuator nodes and a server node. Based on sensor data, a control loop configures the actuators. Operational data is stored in a database and visually presented on a website. The website displays an overview of all the boreholes where all of the sensors data can be read. The control algorithm runs successfully according to its hierarchically priorities. The prototype works as a developement platform and a demonstrating prototype.
