Abstract:
With the broad adoption of service-orientation for the realization of business applications and their provisioning and usage over cloud infrastructures, the topology of the resulting service networks is becoming extremely complex. Due to the composition of services for value-added business capabilities and the reusability of a service in multiple compositions, the execution of one service often depends on other services and changes in its provisioning can affect the health of large parts of the service network. The lack of insight on the relationships between the network components makes the management of the service network's health hard and error prone tasks. This article introduces a service network modeling approach for capturing the topology of a service network at design time. The approach considers the complete modeling process from representation, through collection, to analysis of the relationship information. The major contributions are a generic and adaptable modeling structure, a classification of service network entities and relationships, and a modular management framework automating the modeling process.

Abstract:
A new method is proposed to automatically generate the network control specifications necessary for executing services in a network from communications service specifications by using a knowledge of virtual resource that expresses logical functions in a network. Because these communication service specifications are described by observable terminal behaviors, the communication service specifications can be described without detailed knowledge of the network. The conventional stepwise description for network control specifications is manually performed for each network architecture. Then an expert, who has thorough knowledge of networks, must make a detailed design to comply with the requests of network architecture. Then an expert, who has thorough knowledge of internal networks, must make a detailed design to comply with the requests of network architecture. An expert can define in advance the relationship between a service state and a virtual resource and the relationship between a state transition of a virtual resource and task components and can store this knowledge in a database. Communications service specifications can be described without detailed knowledge of the network, and the network control specifications of the network can be derived from the communication service specifications.

Abstract:
A model was developed for network design of a shipping service for large-scale intermodal liners that captured essential practical issues, including consistency with current services, slot purchasing, inland and maritime transportation, multiple-type containers, and origin-to-destination transit time. The model used a liner shipping hub-and-spoke network to facilitate laden container routing from one port to another. Laden container routing in the inland transportation network was combined with the maritime network by defining a set of candidate export and import ports. Empty container flow is described on the basis of path flow and leg flow in the inland and maritime networks, respectively. The problem of network design for shipping service of an intermodal liner was formulated as a mixed-integer linear programming model. The proposed model was used to design the shipping services for a global liner shipping company.

Abstract:
The trend of 5G mobile networks is increasing with the number of users and the transmission rate. Many operators are turning to small cell and indoor coverage of telecom network service. With the emerging Software Defined Networking and Network Function Virtualization technologies, Internet Service Provider is able to deploy their networks more flexibly and dynamically. In addition to the change of the wireless mobile network deployment model, it also drives the development trend of the Micro Operator (μO). Telecom operators can provide regional network services through public buildings, shopping malls, or industrial sites. In addition, localized network services are provided and bandwidth consumption is reduced. The distributed architecture ofμO tackles computing requirements for applications, data, and services from cloud data center to edge network devices or to the micro data center ofμO. The service model ofμO is capable of reducing network latency in response to the low-latency applications for future 5G edge computing environment. This paper addresses the design pattern of 5G micro operator and proposes a Decision Tree Based Flow Redirection (DTBFR) mechanism to redirect the traffic flows to neighbor service nodes. The DTBFR mechanism allows differentμOs to share network resources and speed up the development of edge computing in the future.

Abstract:
Wireless mesh networks (WMNs) are the only cost-effective networks that support seamless connectivity, wide area network (WAN) coverage, and mobility features. However, the rapid increase in the number of users on these networks has brought an upsurge in competition for available resources and services. Consequently, factors such as link congestion, data collisions, link interferences, etc. are likely to occur during service discovery on these networks. This further degrades their quality of service (QoS). Therefore, the quick and timely discovery of these services becomes an essential parameter in optimizing the performance of service discovery on WMNs. In this paper, we present the design and implementation of an enhanced service discovery model that solves the performance bottleneck incurred by service discovery on WMNs. The proposed model integrates the particle swarm optimization (PSO) and ant colony optimization (ACO) algorithms to improve QoS. We use the PSO algorithm to assign different priorities to services on the network. On the other hand, we use the ACO algorithm to effectively establish the most cost-effective path whenever each transmitter has to be searched to identify whether it possesses the requested service(s). Furthermore, we design and implement the link congestion reduction (LCR) algorithm to define the number of service receivers to be granted access to services simultaneously. We simulate, test, and evaluate the proposed model in Network Simulator 2 (NS2), against ant colony-based multi constraints, QoS-aware service selection (QSS), and FLEXIble Mesh Service Discovery (FLEXI-MSD) models. The results show an average service discovery throughput of 80%, service availability of 96%, service discovery delay of 1.8 s, and success probability of service selection of 89%.

Abstract:
Effective railway freight transportation relies on a well-designed train service network. This paper investigates the train service network design problem at the tactical level for the Chinese railway system. It aims to determine the types of train services to be offered, how many trains of each service are to be dispatched per day (service frequency), and by which train services shipments are to be transported. An integer programming model is proposed to address this problem. The optimization model considers both through train services between nonadjacent yards, and two classes of service between two adjacent yards ( i.e., shuttle train services directly from one yard to its adjacent yard, and local train services that make at least one intermediate stop). The objective of the model is to optimize the transportation of all the shipments with minimal costs. The costs consist of accumulation costs, classification coststrain operation costs, and train travel costs. The NP-hard nature of the problem prevents an exact solution algorithm from finding the optimal solution within a reasonable time, even for small-scale cases. Therefore, an improved genetic algorithm is designed and employed here. To demonstrate the proposed model and the algorithm, a case study on a real-world sub-network in China is carried out. The computational results show that the proposed approach can obtain high-quality solutions with satisfactory speed. Moreover, comparative analysis on a case that assumes all the shuttle train services between any two adjacent yards to be provided without optimization reveals some interesting insights.

Abstract:
As air pollution becomes increasingly severe, express trains play a more important role in shifting road freight and reducing carbon emissions. Thus, the design of railway express shipment service networks has become a key issue, which needs to be addressed urgently both in theory and practice. The railway express shipment service network design problem (RESSNDP) not only involves the selection of train services and determination of service frequency, but it is also associated with shipment routing, which can be viewed as a service network design problem (SNDP) with railway characteristics. This paper proposes a non-linear integer programming model (INLP) which aims at finding a service network and shipment routing plan with minimum cost while satisfying the transportation time constraints of shipments, carrying capacity constraints of train services, flow conservation constraint and logical constraints among decision variables. In addition, a linearization technique was adopted to transform our model into a linear one to obtain a global optimal solution. To evaluate the effectiveness and efficiency of our approach, a small trial problem was solved by the state-of-the-art mathematical programming solver Gurobi 7.5.2.

Abstract:
In a social network people are connected by relationships, business purpose or transaction activity. The increasing demand of social network analysis and how to improve the architecture is of utmost importance for the organizations who are regularly trying to improve the service through social network analysis. Social network analysis views social relationship in terms of network theory. Social networks connect people at very low cost and this network acts as a customer relationship management tool for increasing sales of organization in terms of goods and services. Different models are proposed and utilized in different platforms. In this model, the authors have proposed a cluster-based structure to improve performance of social networks.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2004.<br>Includes bibliographical references (leaves 177-186).<br>Service network design is critical to the profitability of express shipment carriers. In this thesis, we consider two challenging problems associated with designing networks for express shipment service. The first problem is to design an integrated network for premium and deferred services simultaneously. Related existing models adapted to this problem are intractable for realistic instances of this problem: computer memory requirements and solution times are excessive. We introduce a disaggregate information-enhanced column generation approach for this problem that reduces the number of variables to be considered in the integer program from hundreds of thousands to only thousands, allowing us to solve previously unsolvable problem instances. The second problem is to determine the express package service network design in its entirety, including aircraft routings, fleet assignments, and package flow routings, including hub assignments. Existing models applied to this problem have weak associated linear programming bounds and hence, fail to produce quality feasible solutions. For example, for a small network design problem instance it takes days to produce a feasible solution that is provably near- optimal using the best performing existing model. To overcome these tractability challenges, we introduce a new model, referred to as the gateway cover and flow formulation. Applying our new formulation to the same network design instance, it takes only minutes to find an optimal solution.<br>(cont.) Applying our disaggregate information-enhanced column generation approach and gateway cover and flow formulation and solution approach to the network design problems of a large express package service provider, we demonstrate tens of millions of dollars in potential annual operating cost savings and reductions in the numbers of aircraft needed to perform the service. Moreover, we illustrate that, though designed for tactical planning, our new model and solution approach can provide insights for strategic decision-making, such as hub opening/closure, hub capacity expansion, and fleet composition and size.<br>by Su Shen.<br>Ph.D.

Abstract:
The rapid growth and influence of social network services has led many scholars to focus on privacy issues. However, the research described in this thesis was motivated by the small number of design studies that have focused on practical approaches to identifying tacit information from users’ instant non-verbal responses to privacy issues. The research therefore aimed to propose persona models as a design solution for software agent development based on the analysis of users’ emotional and behavioural responses, so as to address privacy issues in social network services. In the definition phase, 21 stakeholders belonging to three key stakeholder groups were recruited for unstandardised semistructured email interviews. Three main considerations for the design of software agents in social network services emerged from the interviews, which were classified into the following categories: comprehensive understanding of users’ perceptions of privacy; user type recognition algorithm for software agent development; and existing software agent enhancement. In the development phase, 50 participants were recruited for the Facebook case study, which included three research strategies: perceptions of privacy questionnaire for user typology; emotional response measurement using Geneva Emotion Wheel; and behavioural response observation using a contextual inquiry method. The participants were classified into four user types by means of cluster analysis: uninformed, trustful, suspicious and neglectful. Each user type’s key emotional responses were identified using Kruskal-Wallis test and Mann-Whitney U test, and key behavioural responses using affinity diagrams. This generated persona models of each user type that reflected the correlations between users’ perceptions of privacy, key emotional responses and key behavioural responses. Two fundamental features of the software agent were also proposed based on the persona models: confirmation and guidance. In the validation phase, software agent prototypes were created based on the proposed persona models. A total of 206 participants completed the online survey which included two sections: perceptions of privacy questionnaire for user typology replication, and key emotional responses measurement before and after the intervention of the software agent prototypes. Cluster analysis replication validated the proposed user typology, and Wilcoxon signed-rank test of key emotional responses validated the proposed persona models. By implementing the research outcomes, the software agent described in this thesis would be able to provide users with appropriate services based on their user types, to reduce the number of those who are still unaware of privacy practice and those who neglect their accounts, and to expand the size of a user group pursuing sound relationships.

Abstract:
Humanity confronts an existential threat without historic precedent. Environmental pressures have reached such intensity and pace of change that the earth system may be irreversibly tipped into a new and unpredictable state. The emerging global reality is, in turn, redefining overall conditions for business success. Addressing these challenges both demands and brings great opportunities for innovation. An important and sometimes neglected aspect of innovation is the design or redesign of business models, which has been identified as a greater source of lasting competitive advantage than new products and services per se. The business model has also been suggested as a new unit of analysis when discussing sustainability. However, this is still a relatively underexplored area. The aim of this work was therefore to develop an approach to business model design that supports strategic sustainable development, i.e., supports organizations to contribute to society’s transition towards sustainability in a way that strengthens the organization.       To be able to design a business model that supports strategic sustainable development, it is necessary to know what sustainability is and how to develop sustainability-promoting, economically viable strategies. Therefore, the Framework for Strategic Sustainable Development, which includes, e.g., an operational definition of sustainability and strategic guidelines for how to approach it, was used as an overarching framework. Specific research methods and techniques included, e.g., literature reviews, questionnaires, interviews, work with focus groups, participatory action research with partner organizations, creative problem solving techniques, modeling, and simulation.   The literature reviews revealed potential sustainability benefits of developing business models in conjunction with product-service systems (PSS). However, a knowledge gap exists regarding how to effectively connect these fields. Arguably, PSS strategies can best contribute to sustainability when business models support their implementation and when both the business models and the PSS strategies are guided by an understanding of strategic sustainable development. Therefore, an integrated approach to Business Model Design for Strategic Sustainable Development was co-developed and tested in PSS innovation work with partners, e.g., companies within the energy and lighting sectors. The tests indicated that the new approach helped to clarify strengths and weaknesses of current business models from a strategic sustainability perspective; to transform an organization’s vision and strategy into a sustainability-framed vision and a sustainability-promoting strategy; and to communicate the new vision and strategy to the value network as a basis for engaging important stakeholders in the change. For example, the approach supported one of the partner companies in its transformation towards providing sustainable PSS solutions in the form of light as a service. Examples of business benefits of the new approach include improved scalability and risk avoidance, which provide a foundation for better investment strategies. Benefits also include improved differentiability and a broadened view on, and a more solid foundation for, collaboration with stakeholders that are increasingly important to sustainable business success.

Abstract:
Thesis (MEng)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: South Africa has a severe HIV (human immunodeficiency virus) burden and the management of the disease is a priority, especially in the public healthcare sector. One element of managing the disease, is determining when to initiate an HIV positive individual onto anti-retroviral therapy (ART), a treatment that the patient will remain on for the remainder of their lifetime. For the majority of HIV positive individuals in the country, this decision is governed by the results of a CD4 (cluster of differentiation 4) test that is performed at set time intervals from the time that the patient is diagnosed with HIV until the patient is initiated onto ART. A device for CD4 measurement at the point of care (POC), the Alere PIMA™, has recently become commercially available. This has prompted a need to evaluate whether CD4 testing at the POC (i.e. at the patient serving healthcare facility) should be incorporated into the South African public healthcare sector's HIV diagnostic service provision model. One challenge associated with the management of HIV in the country is the relatively large percentage of patients that are lost to follow-up at various points in the HIV treatment process. There is extensive evidence that testing CD4 levels at the POC (rather than in a laboratory, as is the current practice) reduces the percentage of patients that are lost to follow-up before being initiated onto ART. Therefore, though POC CD4 testing is more expensive than laboratory-based CD4 testing, the use of this technology in South Africa should be investigated for its potential to positively influence health outcomes. In this research, a multi-objective location science model is used to generate scenarios for the provision of CD4 testing capability. For each scenario, CD4 testing provision at 3 279 ART initiation facilities is considered. For each facility, either (i) a POC device is placed at the site; or (ii) the site's testing workload is referred to one of the 61 CD4 laboratories in the country. To develop this model, the characteristics of eight basic facility location models are compared to the attributes of the real-world problem in order to select the most suitable one for application. The selected model's objective, assumptions and inputs are adjusted in order to adequately model the realworld problem. The model is solved using the cross-entropy method for multi-objective optimisation and the results are verified using a commercial algorithm. Nine scenarios are selected from the acquired Pareto set for detailed presentation. In addition, details on the status quo as well as a scenario where POC testing is used as widely as possible are also presented. These scenarios are selected to provide decision-makers with information on the range of options that should be considered, from no or very limited use to widespread use of POC testing. Arguably the most valuable contribution of this research is to provide an indication of the optimal trade-off points between an improved healthcare outcome due to POC CD4 testing and increased healthcare spending on POC CD4 testing in the South African public healthcare context. This research also contributes to the location science literature and the metaheuristic literature.<br>AFRIKAANSE OPSOMMING: Suid-Afrika gaan gebuk onder `n swaar MIV- (menslike-immuniteitsgebreksvirus-) las en die bestuur van die siekte is `n prioriteit, veral in die openbare gesondheidsorgsektor. Een element in die bestuur van die siekte is om te bepaal wanneer `n MIV-positiewe individu met antiretrovirale- (ARV-)behandeling behoort te begin, waarop pasiënte dan vir die res van hul lewens bly. Vir die meeste MIV-positiewe individue in die land word hierdie besluit bepaal deur die uitslae van `n CD4- (cluster of differentiation 4-)toets wat met vasgestelde tussenposes uitgevoer word vandat die pasiënt met MIV gediagnoseer word totdat hy of sy met ARV-behandeling begin. `n Toestel vir CD4-meting by die punt van sorg (\POC"), die Alere PIMA™, is onlangs kommersieel beskikbaar gestel. Dit het `n behoefte laat ontstaan om te bepaal of CD4-toetsing by die POC (met ander woorde, by die gesondheidsorgfasiliteit waar die pasiënt bedien word) by die MIV-diagnostiese diensleweringsmodel van die Suid-Afrikaanse openbare gesondheidsorgsektor ingesluit behoort te word. Een uitdaging met betrekking tot MIV-bestuur in die land is die betreklik groot persentasie pasiënte wat verlore gaan vir nasorg in die verskillende stadiums van die MIV-behandelingsproses. Heelwat bewyse dui daarop dat die toetsing van CD4-vlakke by die POC (eerder as in `n laboratorium, soos wat tans die praktyk is) die persentasie pasiënte wat verlore gaan vir nasorg voordat hulle met ARV-behandeling kan begin, verminder. Daarom, hoewel CD4-toetsing by die POC duurder is as toetsing in `n laboratorium, behoort die gebruik van hierdie tegnologie in Suid-Afrika ondersoek te word. In hierdie studie is `n meerdoelige liggingswetenskapmodel gebruik om scenario's vir die voorsiening van CD4-toetsvermoë te skep. Vir elke scenario word CD4-toetsvermoë by 3 279 ARV-inisiasie fasiliteite oorweeg. Vir elke fasiliteit word toetsvermoë verskaf deur (i) die plasing van POC-toestelle by die fasiliteit, of (ii) verwysing vir laboratoriumgebaseerde toetsing by een van die 61 CD4-laboratoriums in die land. Die kenmerke van agt basiese fasiliteitsliggingsmodelle is met die kenmerke van die werklike probleem vergelyk om die mees geskikte model vir toepassing op die werklike probleem te bepaal. Die doelwitte, aannames en insette van die gekose model is daarna aangepas om die werklike probleem voldoende te modelleer. Die model is opgelos met behulp van die kruis-entropie-metode vir meerdoelige optimering, waarna die resultate deur middel van `n kommersiële algoritme bevestig is. Nege scenario's uit die verworwe Pareto-stel word uitvoerig aangebied. Daarbenewens beskryf die studieresultate die besonderhede van die status quo sowel as `n scenario waar POC-toetsing so wyd moontlik gebruik word. Hierdie scenario's word aangebied om besluitnemers van inligting te voorsien oor die verskeidenheid moontlikhede wat oorweeg kan word, wat wissel van geen of baie beperkte tot wydverspreide gebruik van POC-toetsing. Die mees beduidende bydrae van hierdie navorsing is stellig dat dit `n aanduiding bied van die optimale kompromie tussen `n verbeterde gesondheidsorguitkoms weens CD4-toetsing by die POC, en verhoogde gesondheidsorgbesteding aan CD4-toetsing by die POC, in die konteks van Suid-Afrikaanse openbare gesondheidsorg. Die navorsing dra ook by tot die ligingswetenskapliteratuur sowel as tot die metaheuristiekliteratuur.

Abstract:
This thesis proposes a collaboration framework for the Web of Things based on the concepts of Service-oriented Architecture and integrated with semantic web technologies to offer new possibilities in terms of efficient asset management during operations requiring multi-actor collaboration. The motivation for the project comes from the rise in disasters where effective cross-organisation collaboration can increase the efficiency of critical information dissemination. Organisational boundaries of participants as well as their IT capability and trust issues hinders the deployment of a multi-party collaboration framework, thereby preventing timely dissemination of critical data. In order to tackle some of these issues, this thesis proposes a new collaboration framework consisting of a resource-based data model, resource-oriented access control mechanism and semantic technologies utilising the Semantic Sensor Network Ontology that can be used simultaneously by multiple actors without impacting each other’s networks and thus increase the efficiency of disaster management and relief operations. The generic design of the framework enables future extensions, thus enabling its exploitation across many application domains. The performance of the framework is evaluated in two areas: the capability of the access control mechanism to scale with increasing number of devices, and the capability of the semantic annotation process to increase in efficiency as more information is provided. The results demonstrate that the proposed framework is fit for purpose.

Abstract:
The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. Business processes are the ways actors work in enterprises and collaborate in value networks, while e-processes support a flexible flow of information between IT systems and business processes. The overall goal of this thesis is to propose methods for business process and e-process design and evaluation for achieving alignment between enterprise goals and IT systems. The methods are based on model-driven approaches, using enterprise and software models. More precisely, the proposed methods can be used for designing models of business processes supporting the fulfilment of enterprise goals in the setting of a value network; for designing models of generic and reusable business processes that support the fulfilment of enterprise goals; for designing models of e-processes that support a flexible alignment of IT systems with business processes; and for evaluating the extent to which business processes are aligned with enterprise goals and IT systems. The result of the thesis can be used to support business and system designers with practical knowledge on how to align business and IT systems in order to create efficient, high-quality, flexible and innovative organisations. The research presented in this thesis has been carried out following the design science paradigm. This paradigm is characterised by the creation of new and innovative artefacts for solving general problems, and the evaluation of their benefits and drawbacks.

Abstract:
AbstractNetwork-Based Biocomputation Circuits (NBCs) offer a new paradigm for solving complex computational problems by utilizing biological agents that operate in parallel to explore manufactured planar devices. The approach can also have future applications in diagnostics and medicine by combining NBCs computational power with the ability to interface with biological material. To realize this potential, devices should be designed in a way that ensures their correctness and robust operation. For this purpose, formal methods and tools can offer significant advantages by allowing investigation of design limitations and detection of errors before manufacturing and experimentation. Here we define a computational model for NBCs by providing formal semantics to NBC circuits. We present a formal verification-based approach and prototype tool that can assist in the design of NBCs by enabling verification of a given design’s correctness. Our tool allows verification of the correctness of NBC designs for several NP-Complete problems, including the Subset Sum, Exact Cover and Satisfiability problems and can be extended to other NBC implementations. Our approach is based on defining transition systems for NBCs and using temporal logic for specifying and proving properties of the design using model checking. Our formal model can also serve as a starting point for computational complexity studies of the power and limitations of NBC systems.

Abstract:
Abstract Refinement of product design processes is recognized as a means for organizations to impact lead times, cost, and quality. Although methods such as the design structure matrix (DSM) exist to analyze design processes, their applications have been limited by overhead in collecting data and maintaining accurate representations. Representation timeliness and resolution issues have typically led to static, high-level process views. In this work, the design process is derived dynamically from an evolving network of design resources inter-related by service dependencies. This network is created to simulate the state of a product design. Through the analysis of resulting dependencies, high-resolution networks of task and parameter interdependency can be extracted. A software module is developed to provide the service of automatically extracting and analyzing the structure of service exchanges in integrated design models. The module provides a matrix or DSM visualization of service relationships and mechanisms to sort resources according to service priority. This allows for realtime evaluation of design processes as models of the product evolve, providing information to guide the strategic addition of resources.

Abstract:
In this paper we discuss the unexplored two-way relationship between distribution network tariff design and the emergence of new business models in the power sector. Distribution network tariffs have traditionally used a cost accounting method. We suggest, instead, the use of a business model framework to analyze the extent to which emerging business models in the power sector change the way electricity distribution network services are priced and packaged.

Abstract:
Emergency Relief (ER) is a Department of Social Services (DSS) funded program, delivered by 197 community organisations (ER Providers) across Australia, to assist people facing a financial crisis with financial/material aid and referrals to other support programs. ER has been playing this important role in Australian communities since 1979. Without ER, more people living in Australia who experience a financial crisis might face further harm such as crippling debt or homelessness. The Emergency Relief National Coordination Group (NCG) was established in April 2020 at the start of the COVID-19 pandemic to advise the Minister for Families and Social Services on the implementation of ER. To inform its advice to the Minister, the NCG partnered with the Institute for Governance at the University of Canberra to conduct research to understand the issues and challenges faced by ER Providers and Service Users in local contexts across Australia. The research involved a desktop review of the existing literature on ER service provision, a large survey which all Commonwealth ER Providers were invited to participate in (and 122 responses were received), interviews with a purposive sample of 18 ER Providers, and the development of a program logic and theory of change for the Commonwealth ER program to assess progress. The surveys and interviews focussed on ER Provider perceptions of the strengths, weaknesses, future challenges, and areas of improvement for current ER provision. The trend of increasing case complexity, the effectiveness of ER service delivery models in achieving outcomes for Service Users, and the significance of volunteering in the sector were investigated. Separately, an evaluation of the performance of the NCG was conducted and a summary of the evaluation is provided as an appendix to this report. Several themes emerged from the review of the existing literature such as service delivery shortcomings in dealing with case complexity, the effectiveness of case management, and repeat requests for service. Interviews with ER workers and Service Users found that an uplift in workforce capability was required to deal with increasing case complexity, leading to recommendations for more training and service standards. Several service evaluations found that ER delivered with case management led to high Service User satisfaction, played an integral role in transforming the lives of people with complex needs, and lowered repeat requests for service. A large longitudinal quantitative study revealed that more time spent with participants substantially decreased the number of repeat requests for service; and, given that repeat requests for service can be an indicator of entrenched poverty, not accessing further services is likely to suggest improvement. The interviews identified the main strengths of ER to be the rapid response and flexible use of funds to stabilise crisis situations and connect people to other supports through strong local networks. Service Users trusted the system because of these strengths, and ER was often an access point to holistic support. There were three main weaknesses identified. First, funding contracts were too short and did not cover the full costs of the program—in particular, case management for complex cases. Second, many Service Users were dependent on ER which was inconsistent with the definition and intent of the program. Third, there was inconsistency in the level of service received by Service Users in different geographic locations. These weaknesses can be improved upon with a joined-up approach featuring co-design and collaborative governance, leading to the successful commissioning of social services. The survey confirmed that volunteers were significant for ER, making up 92% of all workers and 51% of all hours worked in respondent ER programs. Of the 122 respondents, volunteers amounted to 554 full-time equivalents, a contribution valued at $39.4 million. In total there were 8,316 volunteers working in the 122 respondent ER programs. The sector can support and upskill these volunteers (and employees in addition) by developing scalable training solutions such as online training modules, updating ER service standards, and engaging in collaborative learning arrangements where large and small ER Providers share resources. More engagement with peak bodies such as Volunteering Australia might also assist the sector to improve the focus on volunteer engagement. Integrated services achieve better outcomes for complex ER cases—97% of survey respondents either agreed or strongly agreed this was the case. The research identified the dimensions of service integration most relevant to ER Providers to be case management, referrals, the breadth of services offered internally, co-location with interrelated service providers, an established network of support, workforce capability, and Service User engagement. Providers can individually focus on increasing the level of service integration for their ER program to improve their ability to deal with complex cases, which are clearly on the rise. At the system level, a more joined-up approach can also improve service integration across Australia. The key dimensions of this finding are discussed next in more detail. Case management is key for achieving Service User outcomes for complex cases—89% of survey respondents either agreed or strongly agreed this was the case. Interviewees most frequently said they would provide more case management if they could change their service model. Case management allows for more time spent with the Service User, follow up with referral partners, and a higher level of expertise in service delivery to support complex cases. Of course, it is a costly model and not currently funded for all Service Users through ER. Where case management is not available as part of ER, it might be available through a related service that is part of a network of support. Where possible, ER Providers should facilitate access to case management for Service Users who would benefit. At a system level, ER models with a greater component of case management could be implemented as test cases. Referral systems are also key for achieving Service User outcomes, which is reflected in the ER Program Logic presented on page 31. The survey and interview data show that referrals within an integrated service (internal) or in a service hub (co-located) are most effective. Where this is not possible, warm referrals within a trusted network of support are more effective than cold referrals leading to higher take-up and beneficial Service User outcomes. However, cold referrals are most common, pointing to a weakness in ER referral systems. This is because ER Providers do not operate or co-locate with interrelated services in many cases, nor do they have the case management capacity to provide warm referrals in many other cases. For mental illness support, which interviewees identified as one of the most difficult issues to deal with, ER Providers offer an integrated service only 23% of the time, warm referrals 34% of the time, and cold referrals 43% of the time. A focus on referral systems at the individual ER Provider level, and system level through a joined-up approach, might lead to better outcomes for Service Users. The program logic and theory of change for ER have been documented with input from the research findings and included in Section 4.3 on page 31. These show that ER helps people facing a financial crisis to meet their immediate needs, avoid further harm, and access a path to recovery. The research demonstrates that ER is fundamental to supporting vulnerable people in Australia and should therefore continue to be funded by government.

Full text
Abstract:
Despite growing interest in low-speed automated shuttles, pilot deployments have only just begun in a few places in the U.S., and there is a lack of studies that estimate the impacts of a widespread deployment of automated shuttles designed to supplement existing transit networks. This project estimated the potential impacts of automated shuttles based on a deployment scenario generated for a sample geographic area: Santa Clara County, California. The project identified sample deployment markets within Santa Clara County using a GIS screening exercise; tested the mode share changes of an automated shuttle deployment scenario using BEAM, an open-source beta software developed at the Lawrence Berkeley National Laboratory to run traffic simulations with MATSim; elaborated the model outputs within the R environment; and then estimated the related impacts. The main findings have been that the BEAM software, despite still being in its beta version, was able to model a scenario with the automated shuttle service: this report illustrates the potential of the software and the lessons learned. Regarding transportation aspects, the model estimated automated shuttle use throughout the county, with a higher rate of use in the downtown San José area. The shuttles would be preferred mainly by people who had been using gasoline-powered ride hail vehicles for A-to-B trips or going to the bus stop, as well as walking trips and a few car trips directed to public transport stops. As a result, the shuttles contributed to a small decrease in emissions of air pollutants, provided a competitive solution for short trips, and increased the overall use of the public transport system. The shuttles also presented a solution for short night trips—mainly between midnight and 2 am—when there are not many options for moving between points A and B. The conclusion is that the automated shuttle service is a good solution in certain contexts and can increase public transit ridership overall.

Full text
Abstract:
Because ports are considered to be the heart of the maritime transportation system, thereby assessing port performance is necessary for a nation’s development and economic success. This study proposes a novel metric, namely, “port performance index (PPI)”, to determine the overall performance and utilization of inland waterway ports based on six criteria, port facility, port availability, port economics, port service, port connectivity, and port environment. Unlike existing literature, which mainly ranks ports based on quantitative factors, this study utilizes a Bayesian Network (BN) model that focuses on both quantitative and qualitative factors to rank a port. The assessment of inland waterway port performance is further analyzed based on different advanced techniques such as sensitivity analysis and belief propagation. Insights drawn from the study show that all the six criteria are necessary to predict PPI. The study also showed that port service has the highest impact while port economics has the lowest impact among the six criteria on PPI for inland waterway ports.
