Full textAbstract:
Mobile data traffic is expected to increase substantially in the coming years, with data rates 1000 times higher by 2020, having media and content as the main drivers together with a plethora of new end-user services that will challenge existing networks. Concepts and visions associated with the ICT evolution like the network society, 50 billion connected devices, Industrial Internet, Tactile Internet, etc., exemplifies the range of new services that the networks will have to handle. These new services impose extreme requirement to the network like high capacity, low latency, reliability, security, seamless connectivity, etc. In order to face these challenges, the whole end-to-end network has to evolve and adapt, pushing for advances in different areas, such as transport, cloud, core, and radio access networks. This work investigates the impact of envisioned 2020 society scenarios on transport links for mobile backhaul, emphasizing the need for an integrated and flexible/adaptive network as the way to meet the 2020 networks demands. The evolution of heterogeneous networks and ultra-dense network deployments shall also comprise the introduction of adaptive network features, such as dynamic network resource allocation, automatic integration of access nodes, etc. In order to achieve such self-management features in mobile networks, new mechanisms have to be investigated for an integrated backhaul management. First, this thesis performs a feasibility study on the mobile backhaul dimensioning for 2020 5G wireless ultra-dense networks scenarios, aiming to analyze the gap in capacity demand between 4G and 5G networks. Secondly, the concept of an integrated backhaul management is analyzed as a combination of node attachment procedures, in the context of moving networks. In addition, the dynamic network resource allocation concept, based on DWDM-centric transport architecture, was explored for 5G scenarios assuming traffic variation both in time and between different geographical areas. Finally, a short view on techno-economics and network deployments in the 2020 time frame is provided.

Full textAbstract:
Networks and distributed systems have formed the basis of an ongoing communications revolution that has led to the genesis of a wide variety of services. The constantly increasing size and complexity of these systems does not come without problems. In some organisations, the deployment of Information Technology has reached a state where the benefits from downsizing and rightsizing by adding new services are undermined by the effort required to keep the system running. Management of networks and distributed systems in general has a straightforward goal: to provide a productive environment in which work can be performed effectively. The work required for management should be a small fraction of the total effort. Most IT systems are still managed in an ad hoc style without any carefully elaborated plan. In such an environment the success of management decisions depends totally on the qualification and knowledge of the administrator. The thesis provides an analysis of the state of the art in the area of Network and System Management and identifies the key requirements that must be addressed for the provisioning of Integrated Management Services. These include the integration of the different management related aspects (i.e. integration of heterogeneous Network, System and Service Management). The thesis then proposes a new framework, INSMware, for the provision of Management Services. It provides a fundamental basis for the realisation of a new approach to Network and System Management. It is argued that Management Systems can be derived from a set of pre-fabricated and reusable Building Blocks that break up the required functionality into a number of separate entities rather than being developed from scratch. It proposes a high-level logical model in order to accommodate the range of requirements and environments applicable to Integrated Network and System Management that can be used as a reference model. A development methodology is introduced that reflects principles of the proposed approach, and provides guidelines to structure the analysis, design and implementation phases of a management system. The INSMware approach can further be combined with the componentware paradigm for the implementation of the management system. Based on these principles, a prototype for the management of SNMP systems has been implemented using industry standard middleware technologies. It is argued that development of a management system based on Componentware principles can offer a number of benefits. INSMware Components may be re-used and system solutions will become more modular and thereby easier to construct and maintain.

Full textAbstract:
In this dissertation research, we design and analyze integrated mobility and service manage-
ment for network cost minimization in Wireless Mesh Networks (WMNs). We first investigate the
problem of mobility management in WMNs for which we propose two efficient per-user mobility
management schemes based on pointer forwarding, and then a third one that integrates routing-
based location update and pointer forwarding for further performance improvement.
We further study integrated mobility and service management for which we propose protocols
that support efficient mobile data access services with cache consistency management, and mobile
multicast services. We also investigate reliable and secure integrated mobility and service man-
agement in WMNs, and apply the idea to the design of a protocol for secure and reliable mobile
multicast. The most salient feature of our protocols is that they are optimal on a per-user basis
(or on a per-group basis for mobile multicast), that is, the overall network communication cost
incurred is minimized for each individual user (or group). Per-user based optimization is critical
because mobile users normally have vastly different mobility and service characteristics. Thus, the
overall cost saving due to per-user based optimization is cumulatively significant with an increasing
mobile user population.
To evaluate the performance of our proposed protocols, we develop mathematical models and
computational procedures used to compute the network communication cost incurred and build
simulation systems for validating the results obtained from analytical modeling. We identify optimal
design settings under which the network cost is minimized for our mobility and service management
protocols in WMNs. Intensive comparative performance studies are carried out to compare our
protocols with existing work in the literature. The results show that our protocols significantly
outperform existing protocols under identical environmental and operational settings.
We extend the design notion of integrated mobility and service management for cost minimiza-
tion to MANETs and propose a scalable dual-region mobility management scheme for location-
based routing. The basic design concept is to use local regions to complement home regions and
have mobile nodes in the home region of a mobile node serve as location servers for that node. We
develop a mathematical model to derive the optimal home region size and local region size under
which overall network cost incurred is minimized. Through a comparative performance study, we
show that dual-region mobility management outperforms existing mobility management schemes
based on static home regions.Ph. D.

Full textAbstract:
The airline industry is facing unprecedented challenges in generating sufficient revenues to stay in business. Airlines must capture the greatest revenue yield from every flight by leaving no seats unsold and not over filling the cabin with discount fares. To succeed in doing the above airlines must be able to accurately forecast each of their market segments, manage product andprice availability to maximize revenue and react quickly to competitive changes in the market place. Thus seat inventory control and ticket pricing form the two major tools of revenue management. The focus of this paper is to consolidate the ideas of seats inventory control and pricing in order to maximize the revenues generated by an airline network. A continuous time yield management model for a network with multiple legs, multiple fare classes and dynamic price changes for all fare classes is considered. Each fare class has a set of fares from which the optimal fare is chosen based upon the Minimum Acceptable Fare (MAF) which performs the critical role in the decision process. A machine Learning based algorithm, EMSRa based and EMSRb based algorithm for obtaining dynamic policies for combined pricing and allocation. The algorithms are implemented for a sample network with eight cities, eleven logs, thirty origin-destinations(ODs), three fare classes, three levels of fares in each class and ninety itineraries.

Full textAbstract:
This thesis presents an integrated congestion management platform of user traffic at the UNI of the ATM-based network considering the presence of signalling traffic. Integrated congestion management dictates that congestion control schemes are applied during the call access phase (call admission control scheme) and the information transfer phase (buffer control scheme) of user traffic source. The congestion control schemes are devised to meet the congestion performance requirements and to optimize the performance if possible.
UNI call admission and buffer controls developed for the conventional packet-switched network are not applicable to the ATM-based network because of the different input traffic characteristics. In most of the past investigations on the performance of conventional packet-switched networks, the individual input traffic is mostly computer-to-computer data; such individual and aggregate traffic are well-known to follow the Poisson process. On the other hand, ATM-based networks allow a variety of input traffic in addition to the Poisson-distributed traffic. In this thesis, individual user traffic process is modelled as a two-state Markov modulated Poisson process; the aggregate user traffic process is modeled as a batch Bernoulli renewal process under short-term condition and as a fluid process under long-term heavy traffic condition.
The signalling traffic at the UNI carries call control messages and network management
messages originated from the user nodes. The signalling traffic must be serviced quickly since they directly affect call establishment and network efficiency. Up to now, all related congestion control researches only consider user traffic. Consequently, the primary objective for this thesis is to study the effect of the higher-priority signalling
traffic on the multiplexing of user traffic at the UNI. A novel modeling of user traffic multiplexing through the ATM statistical multiplexer at the UNI is proposed: it is characterized
by a queueing model with random service disruptions due to the transport of higher priority signalling traffic.
The congestion performance requirements of the user traffic for the UNI are studied in terms of the stochastic cell loss requirement and the deterministic upper-bound cell delay requirement. However, in order to investigate the stochastic cell loss phenomenon due to buffer overflow, the stochastic queue behaviour must first be examined. Consequently, a novel algorithm to solve the stationary distribution of the queue length process under short-term heavy traffic and finite buffer capacity conditions is presented.
A novel UNI call admission control scheme is proposed, and its objective is to maintain the required network performance assigned to the UNI access-node by exerting call admission control in the call access phase of each user traffic source. It is analyzed using an input-limit static control model employing stochastic ordering between the cell loss ratio random variable and the desired threshold random variable as a criterion to decide if a new call should be admitted. The cell loss ratio random variable has been chosen as the performance objective rather than the long-term-time-averaged cell loss ratio, so as to take into account of the dynamic nature of bursty traffic sources.
A novel UNI intra-node buffer control scheme is proposed, and its objective is to optimize the network performance of the UNI access-node by exerting buffer control in the aggregate information transfer phase of the user traffic sources. It is analyzed by means of a sequential decision process model characterized by a stationary, Markovian and deterministic threshold control policy.Applied Science, Faculty of

Full textAbstract:
The introduction of building management systems in large buildings have improved the control of building services and provided energy savings. However, current building management systems are limited by the physical level of integration of the building's services and the lack of intelligence provided in the control algorithms. This thesis proposes a new approach to the design and operation of building management systems using rule-based artificial intelligence techniques. The main aim of is to manage the services in the building in a more co-ordinated and intelligent manner than is possible by conventional techniques. This approach also aims to reduce the operational cost of the building by automatically tuning the energy consumption in accordance with occupancy profile of the building. A rule-based design methodology is proposed for building management systems. The design adopts the integrated structure made possible by the introduction of a common communications network for building services. The 'intelligence' is coded in the form of rules in such a way that it is both independent of any specific building description and easy to facilitate subsequent modification and addition. This is achieved using an object-oriented approach and classifying the range of data available into defined classes. The rules are divided into two knowledge-bases which are concerned with the building's control and its facilities management respectively. A wide range of rule-based features are proposed to operate on this data structure and are classified in terms of the data classes on which they operate. The concepts presented in this thesis were evaluated using software simulations, mathematical analysis and some hardware implementation. The conclusions of this work are that a rule-based building management system could provide significant enhancements over existing systems in terms of energy savings and improvements for both the building's management staff and its occupants.

As Company X looks to improve customer service and deliver new growth opportunities, it is driving toward a more efficient, aligned and effective organization that eliminates waste through integration of its supply and production networks. The current manufacturing system is optimized for high volume products with low demand variation signals, and is used for all products regardless of demand characteristics. The effects of such a system on the supply network are higher holding cost and stale inventory, while the effects on the business are lost sales and higher total delivered cost. A more responsive production system is an opportunity to reduce strain on the supply network, reduce total delivered cost and improve product fulfillment. Analysis of a portfolio of products demonstrates two main findings: (1) considerable impact of inventory cost on the total delivered cost and (2) a definitive case for differentiated manufacturing strategy - for high and low volume products. Previously only manufacturing cost had been used to make the decision of which system might better fit the goals of providing products in a timely and cost efficient manner. However, the uncovering of the impact of inventory cost on the total delivered cost has challenged that perception. An analysis was also performed on various algorithms which optimize (1) the product lot size and (2) job scheduling on machines. EOQ and a Mixed Integer Program were both analyzed for lot size determination, with the latter demonstrating more cost efficient and production efficient results due to more flexibility with the time scale and the consideration of manufacturing capacity. Finally, a couple of bin packing algorithm heuristics were tested for job scheduling. The results demonstrated significant time savings in job scheduling and have highlighted the need to automate the scheduling process.

Full textAbstract:
La gestion des revenus d’un réseau de compagnies aériennes, un des problèmes le plus critiques dans le secteur du transport aérien, a reçu une attention significative depuis ces dernière décennies. Cependant, de nombreuses problématiques doivent encore être traitées. Cette thèse étudie quatre nouveaux problèmes de la gestion des revenus dans un réseau de compagnies aériennes. D'abord, un problème de dimensionnement de capacité du réseau avec alliances concurrentes est étudié. Dans ce problème, les concurrences horizontales et verticales sont considérées et la demande est supposée déterministe. L’objectif est de maximiser les revenus globaux de l’alliance en déterminant la capacité (en nombre de places) dans les vols pour chaque classe tarifaire de chaque compagnie. Le problème est formulé en programmation linéaire en nombres entiers et résolu à l’aide du solveur CPLEX. Deuxièmement, un problème intégrant la localisation de p-hub médian et le dimensionnement des capacités (places) est étudié pour maximiser une combinaison du bénéfice moyen et du bénéfice au pire cas. Pour ce problème, un seul hub à capacité illimitée est considéré. De plus, les incertitudes sur la demande sont représentées à l’aide d’un ensemble fini des scénarios. Le problème est formulé en programmation stochastique à deux étapes. Ensuite, un algorithme génétique (GA) est proposé pour résoudre le problème pour chaque scénario. Les résultats numériques montrent que la méthode est meilleure que celles dans la littérature qui considèrent uniquement le bénéfice moyen. Le troisième problème étudié est une extension naturelle du deuxième dans lequel la capacité de hub à localiser est limitée et les perturbations qui peuvent impacter la capacité du hub, telles que des conditions météorologiques, sont prises en compte. Deux formulations du problème sont proposées : (1) une programmation stochastique à deux étapes sur la base des scénarios, et (2) optimisation hybride de programmation stochastique à deux étapes à l’aide de pondération. Ensuite, l’approximation moyenne par échantillonnage (SAA) et le GA sont appliqués pour résoudre le problème, respectivement. Les résultats numériques montrent que la SAA est plus performante que le GA. Le quatrième problème est aussi une extension du deuxième problème où la compagnie aérienne doit respecter le niveau d'émissions de CO2 imposé. Le problème est modélisé en programmation stochastique à deux étapes sur la base des scénarios. De plus, une méthode SAA est proposée pour sa résolutionAs one of critical problems in aviation industry, airline network revenue management has received significant attention in recent decades. However, many issues still need to be addressed. This thesis investigates four new airline network revenue management problems. Firstly, a network capacity allocation problem with competitive alliances is studied. In this problem, horizontal and vertical competitions and deterministic demand are considered. The aim is to maximize the global alliance revenue by determining the (seat) capacities in flights for each fare class of each airline. The problem is formulated into a mixed integer programming and is solved by a commercial solver CPLEX. Secondly, an integrated p-hub median location and (seat) capacity allocation problem is investigated to maximize the combined average-case and worst-case profits of an airline. For this problem, an uncapacitated hub is considered and uncertain demand is represented by a finite set of scenarios. The studied problem is formulated based on a two-stage stochastic programming framework. Then a Genetic Algorithm (GA) is proposed to solve the problem for each scenario. Computational results show that the proposed method outperforms those in the literature only considering average-case profit. The third studied problem is a generalization of the second one in which the capacity of hub to be located is limited and disruptions which can impact airline hub capacity, such as adverse weather, are considered. Two formulations of the problem are proposed based on : (1) a scenario-based two-stage stochastic programming, and (2) a weight-based hybrid two-stage stochastic programming-robust optimization framework. Then a Sample Average Approximation (SAA) method and a GA are applied to solve them, respectively. Computational results show that the SAA is more effective than the GA. The fourth problem is also an extension of the second one where an airline is subjected to a CO2 emission limit. The problem is modeled into a scenario-based two-stage stochastic programming. And a SAA method is proposed to solve it

Cybersecurity is a growing research area with direct commercial impact to organizations and companies in every industry. With all other technological advancements in the Internet of Things (IoT), mobile devices, cloud computing, 5G network, and artificial intelligence, the need for cybersecurity is more critical than ever before. These technologies drive the need for tighter cybersecurity implementations, while at the same time act as enablers to provide more advanced security solutions. This paper will discuss a framework that can predict cybersecurity risk by identifying normal network behavior and detect network traffic anomalies. Our research focuses on the analysis of the historical network traffic data to identify network usage trends and security vulnerabilities. Specifically, this thesis will focus on multiple components of the data analytics platform. It explores the big data platform architecture, and data ingestion, analysis, and engineering processes. The experiments were conducted utilizing various time series algorithms (Seasonal ETS, Seasonal ARIMA, TBATS, Double-Seasonal Holt-Winters, and Ensemble methods) and Long Short-Term Memory Recurrent Neural Network algorithm. Upon creating the baselines and forecasting network traffic trends, the anomaly detection algorithm was implemented using specific thresholds to detect network traffic trends that show significant variation from the baseline. Lastly, the network traffic data was analyzed and forecasted in various dimensions: total volume, source vs. destination volume, protocol, port, machine, geography, and network structure and pattern. The experiments were conducted with multiple approaches to get more insights into the network patterns and traffic trends to detect anomalies.

Full textAbstract:
The impetus for this work has evolved from the development of Intellectual Capital (IC) within the Defence Fixed Network (DFN) Integrated Project Team (IPT). Using case study methodology it focuses on an examination of a sample group of DFN desk officers who perform the Customer Relationship Management (CRM) function. The metrics contributing to the DFN IC Model are then contrasted with the results of a benchmark IC study conducted on BT Global services. The purpose of the benchmarking exercise is to determine areas for improvement within the DFN IC Model. The study moves on to describe the commercial and operational context of the DFN IPT and its contracted delivery partner, British Telecom. The relationship between BT and the Ministry of Defence (MOD) is explained and the government's current Public Private Partnerships (PPP) and Private Finance Initiatives (PFI) are discussed. A top level strategic analysis of the DFT IPT, including its immediate operating environment is provided using PEST and SWOT analysis techniques. The study considers the theoretical basis of the literature review and seeks to develop an appropriate IC Model, whilst reviewing its main components. The application of the IC Model to the DFN IPT and BT Global services contexts is also examined. The case study was conducted in two phases. The first phase consisted of the application of the DFN IC Model across a sample of twenty members of the DFN IPT, in order to establish the IC index rating of the organisation. The indices are further developed by the introduction of qualitative data from the subsequent discourse with each of the respondents in support of each of the formal questions. The second phase of the research Model comprised the application of the DFN IC Model to a similar cross section of twenty members of BT Global services, in order to provide a benchmark against which the DFN profile can be further assessed.

Full textAbstract:
Mobility management addresses the issues of how to track and locate a mobile node (MN) efficiently. Service management addresses the issues of how to efficiently deliver services to MNs. This dissertation aims to design and analyze integrated mobility and service management schemes for future all-IP based wireless systems. We propose and analyze per-user regional registration schemes extending from Mobile IP Regional Registration and Hierarchical Mobile IPv6 for integrated mobility and service management with the goal to minimize the network signaling and packet delivery cost in future all-IP based wireless networks.
If access routers in future all-IP based wireless networks are restricted to perform network layer functions only, we investigate the design of intelligent routers, called dynamic mobility anchor points (DMAPs), to implement per-user regional management in IP wireless networks. These DMAPs are access routers (ARs) chosen by individual MNs to act as regional routers to reduce the signaling overhead for intra-regional movements. The DMAP domain size is based on a MN's mobility and service characteristics. A MN optimally determines when and where to launch a DMAP to minimize the network cost in serving the user's mobility and service management operations. We show that there exists an optimal DMAP domain size for each individual MN. We also demonstrate that the DMAP design can easily support failure recovery because of the flexibility of allowing a MN to choose any AR to be the DMAP for mobility and service management.
If access routers are powerful and flexible in future all-IP based networks to perform network-layer and application-layer functions, we propose the use of per-user proxies that can run on access routers. The user proxies can carry service context information such as cached data items and Web processing objects, and perform context-aware functions such as content adaptation for services engaged by the MN to help application executions. We investigate a proxy-based integrated mobility and service management architecture (IMSA) under which a client-side proxy is created on a per-user basis to serve as a gateway between a MN and all services engaged by the MN. Leveraging Mobile IP with route optimization, the proxy runs on an access router and cooperates with the home agent and foreign agent of the MN to maintain the location information of the MN to facilitate data delivery by services engaged by the MN. Further, the proxy optimally determines when to move with the MN so as to minimize the network cost associated with the user's mobility and service management operations.
Finally we investigate a proxy-based integrated cache consistency and mobility management scheme called PICMM to support client-server query-based mobile applications, to improve query performance, the MN stores frequently used data in its cache. The MN's proxy receives invalidation reports or updated data objects from application servers, i.e., corresponding nodes (Cans) for cached data objects stored in the MN. If the MN is connected, the proxy will forward invalidation reports or fresh data objects to the MN. If the MN is disconnected, the proxy will store the invalidation reports or fresh data objects, and, once the MN is reconnected, the proxy will forward the latest cache invalidation report or data objects to the MN. We show that there is an optimal ``service area'' under which the overall cost due to query processing, cache consistency management and mobility management is minimized. To further reduce network traffic, we develop a threshold-based hybrid cache consistency management policy such that whenever a data object is updated at the server, the server sends an invalidation report to the MN through the proxy to invalidate the cached data object only if the size of the data object exceeds the given threshold. Otherwise, the server sends a fresh copy of the data object through the proxy to the MN. We identify the best ``threshold'' value that would minimize the overall network cost.
We develop mathematical models to analyze performance characteristics of DMAP, IMSA and PICMM developed in the dissertation research and demonstrate that they outperform existing schemes that do not consider integrated mobility and service management or that use static regional routers to serve all MNs in the system. The analytical results obtained are validated through extensive simulation. We conclude that integrated mobility and service management can greatly reduce the overall network cost for mobile multimedia and database applications, especially when the application's data service rate is high compared with the MN's mobility rate.Ph.

Full textAbstract:
In advent of the Semantic Web and recent standardization efforts, Ontology has quickly become a popular and core semantic technology. Ontology is seen as a solution provider to knowledge based systems. It facilitates tasks such as knowledge sharing, reuse and intelligent processing by computer agents. A key problem addressed by Ontology is the semantic interoperability problem. Interoperability in general is a common problem in different domain applications and semantic interoperability is the hardest and an ongoing research problem. It is required for systems to exchange knowledge and having the meaning of the knowledge accurately and automatically interpreted by the receiving systems. The innovation is to allow knowledge to be consumed and used accurately in a way that is not foreseen by the original creator. While Ontology promotes semantic interoperability across systems by unifying their knowledge bases through consensual understanding, common engineering and processing practices, it does not solve the semantic interoperability problem at the global level. As individuals are increasingly empowered with tools, ontologies will eventually be created more easily and rapidly at a near individual scale. Global semantic interoperability between heterogeneous ontologies created by small groups of individuals will then be required. Ontology mapping is a mechanism for providing semantic bridges between ontologies. While ontology mapping promotes semantic interoperability across ontologies, it is seen as the solution provider to the global semantic interoperability problem. However, there is no single ontology mapping solution that caters for all problem scenarios. Different applications would require different mapping techniques. In this thesis, we analyze the relations between ontology, semantic interoperability and ontology mapping, and promote an ontology-based semantic interoperability solution. We propose a novel ontology mapping approach namely, OntoMogic. It is based on first order logic and model theory. OntoMogic supports approximate mapping and produces structures (approximate entity correspondence) that represent alignment results between concepts. OntoMogic has been implemented as a coherent system and is applied in different application scenarios. We present case studies in the network configuration, security intrusion detection and IT governance & compliance management domain.

Full textAbstract:
Integrated water management is a wicked public policy problem with no clear path to resolution. This dissertation is an in-depth qualitative comparative analysis of two collaborative governance processes created to tackle complex water problems in New Zealand and Oregon, U.S.A. Both cases convened a wide range of state and non-state actors in efforts to find common ground, build consensus for change, and develop innovative water policy solutions.
The goal of this comparative case study analysis is to gain a better understanding of collaborative network governance frameworks as applied to integrated water management and primary factors for success. The proposition posits that collaborative networks involving public, private, and non-profit actors are better equipped than government-driven efforts to develop desired outcomes. To test this proposition, the research questions probe the role of state and non-state policy actors, conditions for collaboration, strength of actor ties, development of trust and social capital, barriers to success, and the role of climate change as a policy driver in these two case studies.
The comparative case study analysis yields fascinating insights that adds to the network governance literature. In the New Zealand case, a collaborative-led process called the Land and Water Forum (LAWF) showed that this ongoing network offers benefits to creating consensus on complex water issues. LAWF succeeded in moving policy conversations forward where previous government-led efforts had failed. Within the LAWF collaborative network, non-state actors formed strong ties; however, relationships with state actors exhibited weaker ties.
With Oregon's integrated water policy, a collaborative network approach created a more conducive environment for meaningful dialogue among vested interests, and built some levels of interdependency and trust, thus generating a wider array of policy options than through previous legislative and bureaucratic efforts. However, long-standing political, legal, and institutional challenges continue to constrain effective integrated water management and the delivery of integrated outcomes in Oregon. The Oregon case did not exhibit strong leadership within the collaborative to broker challenging policy issues. Also, it faced implementation challenges as one state agency was given responsibility for stewarding integrated water management but lacked authority for implementation or coordination with other state agencies. Overcoming fragmented natural resource governance arrangements remains a daunting challenge.
This research revealed three key findings: (1) in both cases, collaborative network governance worked well for framing and designing new integrated water policies, but encountered implementation challenges; (2) managing the complexities around the intersection of top-down, vertical command and control governance with horizontal collaborative approaches remains an ongoing challenge to New Public Governance; and (3) the two cases represent examples of the use of formal and informal processes for policy development. The benefits of collaborative governance for policy development are substantial, and the limitations appear to be obstacles to overcome and not fatal flaws. The main challenge lies in transitioning from policy and planning to implementing changes on the ground affecting the way we manage water today and in the future.

Doctoral thesis, Saechsische Landesbibliothek- Staats- und Universitaetsbibliothek Dresden, 2015. http://nbn-resolving.de/urn:nbn:de:bsz:14-qucosa-189212.
Full textAbstract:
The planning and implementation of effective water resources management strategies need an assessment of multiple (physical, environmental, and socio-economic) issues, and often requires new research in which knowledge of diverse disciplines are combined in a unified methodological and operational framework. Such integrative research to link different knowledge domains faces several practical challenges. The complexities are further compounded by multiple actors frequently with conflicting interests and multiple uncertainties about the consequences of potential management decisions.
This thesis aims to overcome some of these challenges, and to demonstrate how new modeling approaches can provide successful integrative water resources research. It focuses on the development of new integrated modeling approaches which allow integration of not only physical processes but also socio-economic and environmental issues and uncertainties inherent in water resources systems. To achieve this goal, two new approaches are developed in this thesis.
At first, a Bayesian network (BN)-based decision support tool is developed to conceptualize hydrological and socio-economic interaction for supporting management decisions of coupled groundwater-agricultural systems. The method demonstrates the value of combining different commonly used integrated modeling approaches. Coupled component models are applied to simulate the nonlinearity and feedbacks of strongly interacting groundwater-agricultural hydrosystems. Afterwards, a BN is used to integrate the coupled component model results with empirical knowledge and stakeholder inputs.
In the second part of this thesis, a fuzzy-stochastic multiple criteria decision analysis tool is developed to systematically quantify both probabilistic and fuzzy uncertainties associated with complex hydrosystems management. It integrates physical process-based models, fuzzy logic, expert involvement and stochastic simulation within a general framework.
Subsequently, the proposed new approaches are applied to a water-scarce coastal arid region water management problem in northern Oman, where saltwater intrusion into a coastal aquifer due to excessive groundwater extraction for irrigated agriculture has affected the aquifer sustainability, endangering associated socio-economic conditions as well as traditional social structures.
The results show the effectiveness of the proposed methods. The first method can aid in the impact assessment of alternative management interventions on sustainability of aquifer systems while accounting for economic (agriculture) and societal interests (employment in agricultural sector) in the study area. Results from the second method have provided key decision alternatives which can serve as a platform for negotiation and further exploration. In addition, this approach suits to systematically quantify both probabilistic and fuzzy uncertainties associated with the decision problem. The new approaches can be applied to address the complexities and uncertainties inherent in water resource systems to support management decisions, while serving as a platform for stakeholder participation.

Full textAbstract:
Over recent decades, the stakeholder arena for urban flood management has become well recognised as being complex and dynamic. Various stakeholders are involved before, during and after a flooding event, all of which have different interests and demands. Therefore, an initial stakeholder identification and analysis stage is required before detailed stakeholder engagement strategies can be developed and employed. Drawing on urban flood management in Zhuji, a typical medium-sized city that has suffered urban flooding in China, this research project used a mixed-method research methodology within a single case-study approach to explore the current stakeholder arena for urban flood management in a medium-sized Chinese city. By combining stakeholder salience analysis with social network analysis, this study tries to create a more nuanced insight into the stakeholder arena, so that stakeholder participation in urban flood management can be improved. This thesis produces several findings. First, it provides empirical evidence to show that traditional one-dimensional stakeholder analysis methods such as the level of interest and influence; cooperation and competition; cooperation and threat; and stakeholder interest and power cannot provide an in-depth understanding of a complex and dynamic stakeholder arena, as exists for urban flood management. By way of contrast, the proposed stakeholder analysis approach, which combines both stakeholder salience and network analyses, can create a multi-dimensional understanding of urban flood management stakeholders and allows the initial problem space to be recast into a more detailed or nuanced understanding of the problems presented. This improved understanding of the stakeholder arena and the related problem space provides a more solid information foundation upon which new stakeholder and community engagement practices can be developed. Second, this thesis argues that the Mitchell et al. (1997) salience model experiences limitations in practice. Only five of the seven salience groups were identified in the present research project, with both the Dangerous and Demanding stakeholder groups missing. This indicates that the identification of urban flood management stakeholders in a medium-sized Chinese city is highly dependent on their legitimate claims. Third, the social network analysis used in this project not only explores the relationships between stakeholders, but also provides an opportunity to present other one-dimensional stakeholder attitudes. This enhancement of the data beyond one-dimensional visual representations to dynamic and interactive processes not only better assists policy-makers in developing new and improved engagement practices, it also allows engagement practitioners to educate stakeholders and interactively improve understanding of the situation among those stakeholders. This understanding, in turn, is assumed to facilitate collaborative problem solving.

Full textAbstract:
This dissertation explores the potential contribution of actor-network theory to the investigation of power and hierarchy, science and politics, and the relationship between nature and society in integrated natural resource management (INRM) projects. INRM consists of natural resource management approaches that seek to devolve power and authority from governments and experts to stakeholders, take account of people as part of ecosystems, and directly link conservation and development. While INRM projects represent an important evolution in resource management, they come with particular sets of problems. Specifically, (1) the devolution of decision-making authority to communities provokes issues of power and hierarchy as groups vie to ensure that their interests are adequately taken into account, (2) critiques of expert-led processes shift responsibility for knowledge production to stakeholder groups, thus raising questions about the relationship between science and politics, and (3) attempts to link ecology and economy require a difficult re-conceptualization of the link between nature and society. Actor-network theory (ANT) avoids presuppositions about power, science, nature, and society in order to study how they are produced as effects of networks, thus offering unique conceptual tools to study INRM as a complex, contingent, and innovative network-building process. A qualitative case study of the “Great Bear Rainforest” agreement on British Columbia’s west coast is undertaken to explore these issues in INRM. Analysis of interviews with 34 individuals from environmental organizations, forestry companies, First Nations, consultancies and local and provincial governments, as well as analysis of textual material, reveals how environmentalists (1) generated power by building a network of activists, bears, forest products customers and forestry companies, (2) simultaneously deployed science and politics in their network-building activities and (3) moved away from attempts to purify networks into “nature” and “society,” working instead to directly link ecosystem integrity and human well-being in a new, common “collective” of humans and nonhumans. The research provides significant detail and analysis of a particular case of INRM that will be of use to INRM practitioners, advocates and activists. Additionally, the research demonstrates the applicability of ANT to the investigation of power, science, and nature in INRM projects.

Full textAbstract:
Integrated Pest Management (IPM) technologies have proven to be effective at increasing agricultural productivity and have been credited for providing economic, health, and environmental benefits in many developing countries. In South Asia, population growth and the increasing demand for nutritious foods have put pressure on farmers to produce more food with a relatively inelastic supply of land. Productivity enhancing practices, like IPM, have helped some farmers to meet this demand; however, with over 50 million farmers in Bangladesh and Nepal it is difficult to reach them with information about new agricultural technologies. This study evaluates the current IPM dissemination strategy being implemented by the Bangladesh Department of Agricultural Extension (DAE) and uses a linear programming (LP) model to propose alternative strategies that may extend the total benefits from IPM technologies. Additionally, using data from a household survey, a bivariate probit model and a two-step endogenous participation model are used to identify factors that may influence both knowledge and adoption of IPM practices in three regions of Nepal. The results from the LP model suggest that more farmers could be effectively reached by reallocating funding that is currently used for interpersonal communications (i.e. extension agent visits and farmer field schools) to more widespread methods such as mass media and field days. The model also suggests that a dynamic dissemination strategy is necessary to encourage adoption of IPM technologies with differing characteristics and levels of complexity. The econometric analysis suggests that farmers with â network linkagesâ to agricultural information and inputs, such as membership in a farmer organization, are more likely to be aware of IPM and to adopt IPM practices. The survey data also suggest that farmers who are members of Marketing Planning Committees (MPC) may be more likely to adopt more IPM practices when compared to non-members. Overall, the study suggests that strategically disseminating IPM information is vital to promote the adoption of these technologies in South Asia.Master of Science

Full textAbstract:
Finding the proper balance between availability and cost efficiency is an important concern within spare part management. Spare part suppliers need to respond quickly to customer demand as a stock-out can have severe consequences for both the customer and the supplier. It is critical to identify what items to keep in stock and where to allocate the inventory to avoid stock-outs. This case study was performed at a large high-tech company producing manufacturing equipment to be used in the electronics industry. The aim was to lower the stock-levels of spare parts while not impairing the availability by combining item classification, demand forecasting, and distribution network optimization. A decision diagram for classifying spare parts was constructed using the analytical hierarchy process. Twenty items were classified using the diagram, and the demand for them was forecasted using the Syntetos Boylan Approximationmethod. The shipping cost for spare parts within one region was minimized using a linear optimization model. The analysis showed that equipment criticality, annual usage value, and installed base are critical when classing spare parts. Instead of using five distribution centers in the European region, it was discovered that the shipping costs would decrease if only three warehouses made up the distribution network. The spare parts investigated appeared to follow the typical characteristics for spare parts, showing a low and irregular demand. Hence, demand forecasting seemed to be unnecessary, considering the difficulties in getting satisfactory results. Instead of combining the results from classification, forecasting, and inventory allocation, we suggest that the processes affecting stocking decisions should cooperate and work towards a common objective, namely to satisfy the customer demand in a cost-efficient way. Thus, widening the meaning of taking on an integrated approach to spare part management.Inom hanteringen av reservdelar är det en stor utmaning att hitta rätt avvägning mellan tillgänglighet och kostnadseffektivitet. Leverantörer av reservdelar måste snabbt kunna möta kundefterfrågan eftersom uteblivna leveranser av kritiska reservdelar kan få allvarliga konsekvenser för både kund och leverantör. Vilka artiklar som ska lager-hållas och var de ska lagerhållas är avgörande beslut för att undvika att artiklar rest-noteras. I den här fallstudien, som utfördes på ett stort teknikföretag som tillverkarproduktionsutrustning till elektronikindustrin, var syftet att sänka lagernivåerna av reservdelar utan att göra avkall på tillgängligheten. Detta genom att kombineragruppering av artiklar, beräkning av kommande efterfrågan och optimering av distributionsnätverket. För att klassificera artiklar i grupper med liknande egenskaper skapades ett schematiskt beslutsdiagram med hjälp av metoden AHP. Tjugo artiklar ur sortimentet valdes ut som beslutsdiagrammet testades på. För samma tjugo artiklar gjordes prognoser för den kommande efterfrågan med metoden Syntetos-Boylan-Approximation. Distributionsnätverket i den europeiska regionen optimerades medavseende på fraktkostnad genom att applicera en linjär optimeringsmodell. Hur kritisk en reservdel är för den relaterade maskinens funktionalitet, reservdelensårliga förbrukningsvärde och den geografiska placeringen av installerade maskinervisade sig vara kritiska för att kunna klassificera artiklarna effektivt. Analysen av distributionsnätverket i Europa visade att fraktkostnaderna kan minskas om nätverket utgjordes av tre lager istället för fem som det gör i dagsläget. De tjugo undersökta reservdelarna uppvisade de typiska egenskaperna för reservdelar som har rapporterats i litteraturen som låg och oregelbunden efterfrågan. Att sätta prognoser på efterfrågan verkar obefogat med tanke på komplexiteten i beräkningarna och att de ger få tillfredsställande resultat. Istället för att kombinera resultaten från klassificering, prognoser på efterfrågan och lageroptimering föreslår vi att alla de funktioner i ett företag som arbetar med att tillgodose kundefterfrågan bör samarbeta i högre grad och jobba mot ett gemensamt mål, nämligen att tillgodose kundernas efterfrågan på ett kostnadseffektivt sätt. Således vill vi utvidga betydelsen av att ta en integrerad strategi för reservdelshantering

Mestrado em Engenharia de Computadores e TelemáticaNestes últimos anos tem-se vindo a registar um grande aumento no número de dispositivos ligados à Internet a partir de praticamente qualquer lugar. Assim, para manter-se par com a procura, os Internet Providers têm de melhorar sua rede através da aquisição de mais dispositivos de rede, o que por sua vez aumenta o custo da infra-estrutura. Além disso, isso dificulta ainda mais a gestão das redes devido à sua abordagem centrada no hardware que requer a configuração manual de cada um dos dispositivos de rede. Uma mudança no paradigma atual tem sido estudado e evoluindo ao longo de décadas, mostrando, nos últimos anos, que ele pode realmente ser a futura direção para a rede. SDN é um novo paradigma de rede que facilita a gestão da mesma ao permitir que esta se torne programável. Isso é feito principalmente através da separação dos planos de dados e controlo e também através da criação de abstrações que tornam a rede mais flexível e escalável. O que por sua vez, permite a inovação e gestão mais simples de redes de data center em ambientes de cloud. O objetivo principal desta dissertação é implementar e avaliar uma solução que facilita a gestão, em ambientes de data center, usando este novo paradigma, SDN. Ela fornece configuração transparente e automática da rede subjacente, a fim de permitir a comunicação entre os nós com requisitos de largura de banda especificados. Além disso, também realiza a monitorização de balanceamento de carga para optimizar o uso de tráfego na rede. Esta dissertação apresenta a solução desenvolvida que utiliza um controlador de SDN e OpenvSwitch. A solução faz uso de ambos os protocolos OpenFlow e OVSDB, bem como os módulos do controlador OpenDaylight. A interacção com o controlador é realizada através do uso do REST APIs fornecidas pelo controlador acima mencionado. Durante a fase de avaliação, vários cenários de teste foram executados a fim de avaliar a correção e o desempenho do sistema que interage com a rede. A aplicação comportou-se razoavelmente bem por ser capaz de aplicar a largura de banda especificada on-demand (QoS) de uma maneira simples e sem falhas. Do mesmo modo, o balanceamento de carga foi também aplicado com sucesso, sem perder a comunicação entre os nós. Tudo isto foi realizado com overhead moderado (em termos de tempo de instalação e da quantidade de dados enviados para gerir a rede). Em conclusão, a solução mostra-se promissora pela sua facilidade na gestão de redes em data centers.
These past few years we have been experiencing a large increase in the number of devices connected to the Internet from almost anywhere. Thus, to keep up with the demand, Service Providers have to upgrade their network by acquiring more network devices, which greatly increases the infrastructure’s cost. In addition, this hampers even more the management of the networks due to their hardware centric approach which requires manual configuration of each of the network devices. A change in the current paradigm has been studied and evolving for decades, showing, in the last years, that it can actually be the future direction for networking. SDN is a modern networking paradigm that eases network management by enable the network to be programmable. This is done mainly through the separation of data and control planes and also through the creation of abstractions that make the network more flexible and scalable. Which, in turn enables innovation and simpler management to data center networks in cloud environments. The main objective of this dissertation is to implement and evaluate a solution that eases the management in data center environments using this new paradigm, SDN. It provides seamless and automatic configuration of the underlying network in order to allow communication between nodes with on-demand bandwidth requirements. In addition, it also performs load balance monitoring to optimize the traffic usage on the network. This dissertation presents the developed solution which uses a SDN controller and OpenvSwitch. The solution makes use of both OpenFlow and OVSDB protocols as well as OpenDaylight controller’s modules. The interaction with the controller is performed through the use of the REST APIs provided by the above mentioned controller. During the evaluation stage, several test scenarios were executed in order to evaluate the correctness and performance of the system interacting with the network. The application behaved reasonably well by being able to apply the specified bandwidth on-demand (QoS) in a simple manner without flaws. Similarly, the load balance was also successfully applied without loosing communication between the hosts. All this was accomplished with moderate overhead (in terms of time of installation and quantity of data sent to manage the network). In conclusion, the solution shows to be promising for the ease of management in data center networks.

Thesis (MPhil)--Stellenbosch University, 2004.ENGLISH ABSTRACT: The Education Management Information System (EMIS) is the business unit that is responsible for information management and business reporting in the Department of Education. EMIS finds it difficult to provide high quality information to the Department of Education internally and its stakeholders externally and attributes the reduction of the quality of its education information to factors such as the organisational nature of the South African education system, the lack of information management standards and practices, the low level of information technology skills in EMIS, the existence of a multitude of disparate information systems in the Department of Education and Provincial Education Departments, and the apparent discontinuity in the flow of information from education institution level to the national department and back. Most research in information management confirmed the state of EMIS as being typical of most large organisations whose functioning depends on the quality of their information. The factors that influence information quality in EMIS had been identified as accuracy, timeliness, consistency and relevance of the information. A “quick-fix” to the information problem is not possible but research in information systems management indicates that there are trends in the electronic business arena that may provide an acceptable solution to most of the problems encountered by EMIS. This report investigates the nature of EMIS problems in terms of information management and investigates possible solutions to the problems. The investigation is done within the framework of acknowledged information systems planning process and aligned to the process model of information management. An exposition is given on the theory pertaining to information management, information systems and information systems management to give insight into the particular fields of study and their interdependencies. A section on business intelligence is included since business reporting is the primary function of EMIS. Investigations into information systems development indicate an exponential growth in electronic technology development specifically the Internet and the Web. The information systems plan provides the framework or set of guidelines to determine the information systems solution that will be able to solve their problems. The research report included four stages of the information systems plan framework. The first stage pertains to the identification of minimum information required from the education sector and supporting sectors to provide high quality education information for decision-making and planning. The second stage determines and benchmarks the state of EMIS in terms of information management processes. The third stage investigates the trends in electronic business and specifically electronic information systems applications. Current best practices indicate that a possible solution to information management problems in large organisations is the application of a web-based, electronic, enterprise-wide, integrated information system.
AFRIKAANSE OPSOMMING: EMIS as ‘n besigheidseenheid in die nasionale Onderwysdepartement is verantwoordelik vir inligtingsbestuur en verslaggewing. EMIS vind dit moeilik om hoë kwaliteit inligting intern aan die onderwysdepartement en ekstern aan sy rolspelers te verskaf. en skryf die verlaging in die kwaliteit van inligting toe aan faktore soos die organisasiestruktuur van die Suid Afrikaanse onderwysstelsel, die gebrek aan standaarde vir inligtingsbestuur en -praktyke, die lae vlak van inligtingstegnologiekennis van die personeel in EMIS, die bestaan van ‘n magdom van ongelyksoortige inligtingstelsels in die nasionale onderwysdepartement en provinsiale onderwysdepartemente en die sigbare diskontinuïteit in die vloei van inligting vanaf die onderwysinrigtings na die nasionale onderwysdepartement en terug. Die meeste navorsing in inligtingsbestuur bevestig dat die toestand waarin EMIS verkeer tipies is van die meeste groot organisasies wie se funksionering van die kwaliteit van hulle inligting afhang. Die faktore wat ‘n rol speel in die kwaliteit van inligting in EMIS word geïdentifiseer as akkuraatheid, tydigheid, uniformiteit en geldigheid. ‘n Vinnige oplossing vir die inligtingsprobleem is nie moontlik nie maar navorsing in inligtingstelselsbestuur dui aan dat daar tendense in die rigting van elektroniese besigheidarena is wat aanvaarbare oplossings bied vir die meeste van EMIS se probleme. Hierdie verslag ondersoek die aard van EMIS se probleme in terme van inligtingsbestuur en ondersoek moontlike oplossings vir die probleme. Die ondersoek word gedoen binne die raamwerk van ‘n aanvaarde inligtingstelsel-beplanningsproses wat opgestel is om binne die prosesmodel vir inligtingsbestuur te val. ‘n Uiteensetting van die teorie ten opsigte van inligtingsbestuur, inligtingstelsels en inligtingstelselbestuur word gegee ten einde insig oor die betrokke studieterreine en hul interafhanklikheid te gee. ‘n Afdeling oor besigheidsintelligensie word ingesluit aangesien besigheidsverslaggewing die primêre funksie van EMIS is. ‘n Ondersoek na inligtingstelselontwikkeling dui op ‘n eksponensiële groei in die ontwikkeling van die elektroniese tegnologiebedryf en spesifiek die Internet en Web. Die inligtingstelselsplan voorsien die raamwerk of riglyne waarbinne die inligtingstelseloplossing gesoek kan word. Die navorsingsverslag sluit vier fases van die raamwerk van die inligtingstelselsplan in. Die eerste fase het te make met die identifisering van die minimum inligting wat nodig is vir besluitneming en beplanning. Die tweede fase stel die toestand van EMIS ten opsigte van inligtingsbestuur vas. Die derde fase ondersoek die neigings in elektroniese besigheidstransaksies en toepassings. Huidige beste praktyke dui aan dat ‘n moontlike oplossing vir die inligtingsbestuurprobleme van groot organisasies die toepassing van ‘n web-gebaseerde, elektroniese, geïntegreerde inligtingstelsel, wat al die komponente van die onderneming insluit, is.

The focus of this dissertation is the development of resource management schemes for integrated networks, with the major contributions being: (i) the development of an optimal adaptive buffer management scheme for the packet-switched subsystem, (ii) the integration of a moveable-boundary hybrid switching scheme with the time assigned speech interpolation technique for implementing a congestion control mechanism for the packet-switched subsystem, and (iii) the development of an adaptive hierarchical scheme for implementing the access control and routing functions within the circuit-switched subsystem. The problem of buffer management at an integrated network node is formulated as a nonlinear programming problem with a convex objective function and an interative solution technique with fast convergence is proposed for a real-time implementation of the buffer management scheme in practical environments. In order to exercise an additional degree of control over the packet-blocking probability at each hybrid-switched link within the network, a new multiplexing scheme based on the integration of the moveable-boundary hybrid switching scheme and the time assigned speech interpolation technique is presented in this dissertation. The tradeoff between the corresponding decrease in the packet blocking probability and the increase in the circuit freezeout fraction is demonstrated by a detailed queueing analysis of the multiplexer. Specific algorithms are also presented in this dissertation for the solution of the access control and routing problems within the circuit-switched subsystem. In particular, an access control scheme is developed by solving an integer programming problem formulated using the policy of complete partitioning of the available bandwidth among the competing user classes. As an alternative to the completely partitioned approach, the problem of traffic routing is considered in a network that supports homogeneous traffic classes based on the policy of complete sharing. Finally, for the general case of networks with heterogeneous traffic classes, a hierarchical scheme is developed for the implementation of the access control and the routing functions at two functional levels, where the access control is implemented by the network supervisor who solves an appropriate linear integer programming problem periodically, and the routing function is handled by the individual nodes of the network on a distributed basis.

Although they are related subjects, they are often analyzed under different perspectives. Its general objective is to understand how the integration between communication and marketing occurs, both in theory and in practice, observing as an example cases companies participating in the Petrogás SE Network. These companies are certified by ISO and audited periodically, in addition it has as system of management the Integrated Management System (SGI). From the protocol created by Yin (2015) a research was done on how the integrated communication of marketing has been worked in these institutional environments. Our intention was to understand if having an Integrated Management System makes the communication and marketing of these companies professional or close to what is said in theory. In order to do so, a qualitative research was done using the methodology. Unique and holistic case study proposed by Yin (2015), being used as participant observation method and semi-structured interviews. Through the study it can be seen that even in the strict methods proposed by international norms, both communication and marketing have been neglected in these institutions. There is a great lack of knowledge and lack of preparation regarding the areas addressed by the administrators and the absence of specific professionals to implement organizational communication actions and their integration into marketing.

Nosso intuito foi perceber se o fato de terem um Sistema de Gestão Integrada faz com que a comunicação e o marketing dessas empresas sejam profissionais, ou se aproximem do que é dito na teoria. Para tanto foi feita uma pesquisa qualitativa, com utilização da metodologia Estudo de caso único e holístico proposto por Yin (2015) sendo utilizados como método de coleta observação participante e entrevistas semiestruturadas. Através do estudo pode-se perceber que mesmo atendendo a métodos rígidos propostos por normas internacionais, tanto a comunicação, quanto o marketing vem sendo muito negligenciados nessas instituições. Existe um grande desconhecimento e despreparo com relação as áreas abordadas por parte dos administradores e ausência de profissionais específicos para implantação de ações de comunicação organizacional e sua integração ao marketing.

Esta tesis nos ha permitido trasladar algunos conceptos teóricos de la computación ubicua a escenarios reales, identificando las necesidades específicas de diferentes tipos de aplicaciones. Con el fin de alcanzar este objetivo, proponemos dos prototipos que proporcionan servicios sensibles al contexto en diferentes entornos, tales como conferencias o salas de recuperación en hospitales. Estos prototipos experimentales explotan la tecnología Bluetooth para ofrecer información basada en las preferencias del usuario. En ambos casos, hemos llevado a cabo algunos experimentos con el fin de evaluar el comportamiento de los sistemas y su rendimento.
También abordamos en esta tesis el problema de la autoconfiguración de redes MANET basadas en el estándar 802.11 a través de dos soluciones novedosas. La primera es una solución centralizada que se basa en la tecnología Bluetooth, mientras la segunda es una solución distribuida que no necesita recurrir a ninguna tecnología adicional, ya que se basa en el uso del parámetro SSID. Ambos métodos se han diseñado para permitir que usuarios no expertos puedan unirse a una red MANET de forma transparente, proporcionando una configuración automática, rápida, y fiable de los terminales. Los resultados experimentales en implementaciones reales nos han permitido evaluar el rendimiento de las soluciones propuestas y demostrar que las estaciones cercanas se pueden configurar en pocos segundos. Además, hemos comparado ambas soluciones entre sí para poner de manifiesto las diferentes ventajas y desventajas en cuanto a rendimento.

Full textAbstract:
With the advent of the Internet, co-operating enterprises are increasingly sharing consumer data to deliver them information-rich online experiences with value-added services. At the same time, technological advances in web services standards based on a Service Oriented Architecture (SOA) design have enabled heterogeneous Business-to-Business (B2B) integration between enterprises. End-to-End business processes that span across multiple enterprises can be developed using the Business Process Execution Language (BPEL). However, such processes must address issues that normally do not arise for processes within a single enterprise. A framework is needed which supports a SOA-enabled business process management approach but also has technical infrastructure to address issues related to identity, privacy, compliance, monitoring and people interaction. In our thesis, we accomplish this using a framework that supports the design, implementation and management of trusted B2B processes defined using the BPEL standard and deployed into Circle of Trust architecture as specified by the Liberty Alliance federated identity standards. A key contribution of our thesis was to extend the Circle of Trust architecture with a new entity that introduces components to help businesses manage their B2B processes. Two use-case scenarios involving information-rich B2B processes were implemented to evaluate our framework.

Full textAbstract:
The Radio Frequency Identification (RFID), which includes passive and active systems and is the hottest Auto-ID technology nowadays, and the wireless sensor network (WSN), which is one of the focusing topics on monitoring and control, are two fast-growing technologies that have shown great potential in future logistics management applications. However, an information system for logistics applications is always expected to answer four questions: Who, What, When and Where (4Ws), and neither of the two technologies is able to provide complete information for all of them. WSN aims to provide environment monitoring and control regarded as When and What , while RFID focuses on automatic identification of various objects and provides Who (ID). Most people usually think RFID can provide Where at all the time. But what normal passive RFID does is to tell us where an object was the last time it went through a reader, and normal active RFID only tells whether an object is presenting on site. This could sometimes be insufficient for certain applications that require more accurate location awareness, for which a system with real-time localization (RTLS), which is an extended concept of RFID, will be necessary to answer Where constantly. As WSN and various RFID technologies provide information for different but complementary parts of the 4Ws, a hybrid system that gives a complete answer by combining all of them could be promising in future logistics management applications. Unfortunately, in the last decade those technologies have been emerging and developing independently, with little research been done in how they could be integrated. This thesis aims to develop a framework for the network level architecture design of such hybrid system for on-site resource management applications in logistics centres. The various architectures proposed in this thesis are designed to address different levels of requirements in the hierarchy of needs, from single integration to hybrid system with real-time localization. The contribution of this thesis consists of six parts. Firstly, two new concepts, Reader as a sensor and Tag as a sensor , which lead to RAS and TAS architectures respectively, for single integrations of RFID and WSN in various scenarios with existing systems; Secondly, a integrated ZigBee RFID Sensor Network Architecture for hybrid integration; Thirdly, a connectionless inventory tracking architecture (CITA) and its battery consumption model adding location awareness for inventory tracking in Hybrid ZigBee RFID Sensor Networks; Fourthly, a connectionless stochastic reference beacon architecture (COSBA) adding location awareness for high mobility target tracking in Hybrid ZigBee RFID Sensor Networks; Fifthly, improving connectionless stochastic beacon transmission performance with two proposed beacon transmission models, the Fully Stochastic Reference Beacon (FSRB) model and the Time Slot Based Stochastic Reference Beacon (TSSRB) model; Sixthly, case study of the proposed frameworks in Humanitarian Logistics Centres (HLCs). The research in this thesis is based on ZigBee/IEEE802.15.4, which is currently the most widely used WSN technology. The proposed architectures are demonstrated through hardware implementation and lab tests, as well as mathematic derivation and Matlab simulations for their corresponding performance models. All the tests and simulations of my designs have verified feasibility and features of our designs compared with the traditional systems.

Full textAbstract:
Towards sustainability forces process industries to change their traditional patterns. Therefore, efficient retrofitting has been a significant challenge and raised several issues, motivating the process system engineering (PSE) to develop models. These models mainly aim to optimize profitability, cost reduction, energy consumption, demand satisfaction, the environmental impact associated with the production process, and social acceptance. Nevertheless, such optimization is significantly complicated if considering the presence of uncertainty and seeking compromised outcomes.
This thesis aims to extend a general model to facilitate retrofitting in industrial processes and expedite optimization of the issues. Such a contribution based on developing efficient mathematical models allows coordinating many decision variables synchronizing the production and distribution tasks in terms of economic and environmental criteria.
This thesis presents an overview of the retrofitting requirement towards sustainable material/energy networks, describing and analyzing the current methods, tools, and models used and identifying the most relevant open issues.
The second part focused on developing current models stressing energy integration in the processing system. This part first explores how the economic performance of the network can be enhanced and environmental impacts improved simultaneously by integrating an energy generation unit into the production system. Furthermore, the network sustainability performance was explored under demand uncertainties. Additional risk indicators (including financial and environmental risk metrics) have been included to add risk management capability to the model. This part also explores the strategies that efficiently select the number of scenarios.
Consequently, a novel generalized mathematical formulation that integrates equations regarding energy generation and material production decision variables is efficiently solved. The effect of uncertainty on the economic and environmental performance is analyzed by using risk analysis. Finally, the model was extended to solve multi-renewable energy generation integrated into the multi-product production process under demand uncertainty. The importance and effect of the energy/material integration over the network configuration are analyzed through sensitivity analysis.
The third part of this thesis provides the conclusions and further work to be developed.El camino hacia la sostenibilidad obliga a las industrias de procesos a cambiar los patrones de trabajo tradicionales. La modernización eficiente es un importante desafío que plantea múltiples problemas, lo que ha llevado a la ingeniería de sistemas de procesos (PSE) a desarrollar modelos que intentan no solo optimizar la rentabilidad, reducir de costes o satisfacer demanda de productos y servicios, sino también afrontar el impacto ambiental asociado al proceso productivo y la aceptación social de dicho proceso, en entornos volátiles, en los que la consideración de la incertidumbre asociada al escenario de trabajo es esencial. Esta tesis tiene como objetivo ampliar y flexibilizar los modelos de gestión de cadena de suministro existentes para facilitar la retroadaptación de los procesos industriales y agilizar la optimización de los problemas de toma de decisiones en este entorno. Tal aporte está basado en el desarrollo de modelos matemáticos eficientes que permite coordinar diferentes variables de decisión, sincronizando las tareas de producción y distribución en términos de criterios económicos y ambientales. Para ello, en primer lugar se presenta una visión general del requisito de adaptación hacia redes de materiales / energía sostenibles, describiendo y analizando los métodos, herramientas y modelos actuales utilizados e identificando los problemas abiertos más relevantes. La segunda parte de esta Tesis se centra en el desarrollo de modelos que enfatizan la integración energética en el sistema de proceso. Esta parte explora primero cómo se pueden mejorar simultáneamente el desempeño económico de la red y los impactos ambientales mediante la integración de unidades de generación de energía en el sistema de producción. Además, se ha explorado el rendimiento de la sostenibilidad de la red bajo incertidumbre en la demanda. Se han incluido indicadores de riesgo adicionales (incluidas métricas de riesgo financiero y ambiental) para incorporar en el modelo la capacidad de gestión de riesgos. Esta parte también explora las estrategias que seleccionan de manera eficiente el número de escenarios a considerar. En consecuencia, se resuelve de forma eficiente una formulación matemática novedosa que generaliza e integra ecuaciones relativas a decisiones de producción energética y de materiales. El efecto de la incertidumbre sobre el desempeño económico y ambiental se analiza mediante análisis de riesgo. Finalmente, el modelo se amplía para abordar la utilización coordinada de diferentes formas de energía renovable, y su integración en el proceso de producción multi-producto bajo incertidumbre en la demanda. La importancia y el efecto de la integración de la toma de decisiones sobre la configuración de la red se discuten a través de diferentes análisis de sensibilidad. La tercera parte de esta tesis resume las conclusiones de todos estos trabajos y plantea ampliaciones y nuevas líneas de mejora que surgen a partir de los modelos y procedimientos desarrollados en esta tesis.

Thesis (PhD (Industrial Engineering))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: Innovation is important for competitiveness. It thrives on the availability of novel public and private domain knowledge. Thus the ability to access, analyze, synthesize, share, and re-use knowledge is paramount to enabling innovation within the different partners of the supply chain. These activities grow the available pool of knowledge. It also facilitates learning from mistakes, as well as capturing and enhancing opportunities for future innovation. Proactively networking resources within a formal and informal structure improve the ability of any participating enterprise to use/re-use knowledge, in a concurrently growing knowledge base. Such a "Knowledge Network” (KN) enhances knowledge sharing between and among individuals, groups and organizations in informal and formal ways. This network is also scalable in the sense that more individuals and enterprise may join the network as success cases are reported on. It is clear that knowing how to design, deploy and operate a Knowledge Network could be highly beneficial. How to successfully design and deploy a KN is a challenge and has been widely researched to a limited extent within in the past decade. The design, deploy and operate functions require understanding of social processes and how people learn and share knowledge. KN management requires a proactive, systematic approach to the planning and deployment of a formalized network for knowledge creation and transfer. It addresses promoting and improving conditions to cultivate informal and formal networking within a larger collaborative network of enterprises. This dissertation presents a refined methodology for initiating, deploying, managing and operating an Innovation Project based on the available research reported in this domain. It incorporates concepts of generic, partial and specific roadmaps, best practices, templates and examples and allows individual teams to capture knowledge about specific projects and expertise in context for later re-use.
AFRIKAANSE OPSOMMING: Om mededingend te kan wees, is innovasie belangrik. Laasgenoemde floreer op die beskikbaarheid van nuwe publieke, sowel as private domein kennis. Dus is die kundigheid om kennis te assesseer, te analiseer, saam te vat, uit te ruil met ander en dan weer te gebruik van die uiterste belang om innovasie moontlik te maak vir die onderskeie vennote in die voorsieningsketting. Hierdie genoemde aktiwiteite vergroot die beskikbare poel van kennis. Daarbenewens fasiliteer dit ook leer uit foute, sowel as die vasvang en versterking van geleenthede vir toekomstige innovasie. Deur pro-aktief en vindingryk van netwerk bronne gebruik te maak, binne ʼn formele sowel as informele struktuur, word die moontlikheid van enige deelnemende onderneming om kennis te gebruik of te hergebruik, vergroot in ʼn gelyktydig groeiende kennisbasis. So ʼn “Kennis Netwerk” (KN) versterk die uitruil van kennis tussen individue, groepe en organisasies op informele sowel as formele maniere. Hierdie netwerk is ook meetbaar in die sin dat hoe meer suksesse aangekondig word, deur individue en organisasies wat aansluit, hoe meer ondernemings wil aansluit. Dit is duidelik dat kennis ten opsigte van die ontwerp, ontplooiing en bestuur van ʼn Kennis Netwerk uiters voordelig kan wees. Dit is ʼn uitdaging om ʼn Kennis Netwerk suksesvol te ontwerp en te ontplooi en daar is die afgelope dekade op ʼn wye front beperkte navorsing op hierdie terrein gedoen. Die ontwerp, ontplooiing en bestuursfunksies vereis ʼn goeie begrip van sosiale prosesse met beklemtoning van hoe mense leer en kennis uitruil. Die bestuur van ʼn Kennis Netwerk moet pro-aktief en sistematies benader word, ten opsigte van die beplanning en ontplooiing van ʼn geformaliseerde netwerk vir die skep en oordrag van kennis. Die bevordering en verbetering van omstandighede kan formele sowel as informele netwerkbeoefening binne ʼn groter samewerkende netwerk van ondernemings vestig. Hierdie proefskrif bied ʼn verfynde metodologie vir die inisiëring, ontplooiing en bestuur van ʼn Innovasie Projek wat gebaseer is op die beskikbare navorsing wat in hierdie domein gerapporteer is. Dit behels konsepte van generiese, gedeeltelike en spesifieke padkaarte, asook die beste praktyke, patrone en voorbeelde en gee geleentheid vir individuele spanne om kennis ten opsigte van spesifieke projekte en kundigheid in konteks te bekom vir latere hergebruik.

Previous issue date: 2014-10-27The integrated network management system aims to manage the telecommunications network, regardless of network elements technology in order to identify the causes of problems, providing a more assertive decision making to remedy these problems and make the network available and operational. Thus, can to cater to the market that is increasingly demanding with the level of quality telecommunications products and services. Given this need, integrated networks management system belongs to a real company needs to respond quickly to customers' expectations with respect to requests for new functions system, and perform technology upgrades periodically. However, the integrated network management system development use centered-source technologies, and it requires great effort and hinders reuse. In this context, this master's project presents a proposal to facilitate the integrated network management system development using the techniques of MDD (Model Driven Development). MDD emphasizes the use of models in software development. These models specify the rules of business domain at a high level of abstraction, i.e., regardless of the programming language and to run the software platform. With appropriate computational tools transformations of models in the source code are performed. The use of MDD can provide software reuse procedurally, enabling faster development, lower cost, produce a flexible software and enable faster modifications. To apply MDD approach, a Domain Specific Language (DSL) for the configuration management of integrated network management system setting is designed to facilitate the inclusion of a new technology to be managed by the system, while providing faster development and with fewer errors of code. To evaluate the proposal, an experiment was conducted with the participation of software developers that know the system and work in this real company. The results showed that according to the descriptive analyses there was a reduction in the time spent in application development when it was used DSL compared to the specialization of classes. However, hypotheses tests showed no such reduction. The insertion of errors in the code occurred only in applications developed using specialization classes. The use of DSL provided a broader view of the business rule and you do not need knowledge of the programming language, once the code was automatically generated.
Um sistema de gerenciamento integrado de redes tem o objetivo de gerenciar uma rede de telecomunicações, independentemente da tecnologia dos elementos de rede, a fim de identificar as causas de problemas, proporcionando a tomada de decisão mais assertiva para saná-los e deixar a rede disponível e operacional. Dessa forma, o mercado que está cada vez mais exigente com o nível de qualidade dos produtos e serviços de telecomunicações é atendido. Diante dessa necessidade, o sistema de gerenciamento integrado de redes de uma empresa real precisa atender rapidamente às expectativas dos clientes com relação às solicitações de novas funções do sistema, assim como realizar atualizações tecnológicas periodicamente. Porém, o desenvolvimento do sistema de gerenciamento integrado de redes dessa empresa utiliza tecnologias centradas em código-fonte, o que implica em grande esforço e dificulta a sua reutilização. Neste contexto, este projeto de mestrado apresenta uma proposta para facilitar o desenvolvimento do sistema de gerenciamento integrado de redes utilizando as técnicas de MDD (Desenvolvimento Dirigido a Modelos). MDD enfatiza a utilização de modelos no desenvolvimento do software. Esses modelos especificam as regras de negócio de domínio em um alto nível de abstração, ou seja, independentemente da linguagem de programação e da plataforma de execução do software. Com ferramentas computacionais adequadas são realizadas as transformações dos modelos em código-fonte. A utilização de MDD pode proporcionar reúso de software de forma processual, possibilitar um desenvolvimento mais rápido, com menor custo, produzir um software flexível e possibilitar modificações mais rapidamente. Para aplicar a abordagem de MDD, uma linguagem específica de domínio (DSL) para a gerência de configuração do sistema de gerenciamento integrado de redes foi desenvolvida. Tem como objetivo facilitar a inclusão de uma nova tecnologia a ser gerenciada pelo sistema e ao mesmo tempo proporcionar um desenvolvimento mais rápido, com menos erros de código. Para avaliar a proposta foi realizado um experimento com a participação dos atuais desenvolvedores de software de uma empresa real. Os resultados obtidos mostraram que, segundo a análise descritiva, houve redução do tempo gasto no desenvolvimento das aplicações quando foi utilizada a DSL em comparação com o desenvolvimento baseado em especialização das classes. Porém, os testes das hipóteses não apresentaram tal redução. A inserção de erros no código ocorreu somente nas aplicações desenvolvidas utilizando especialização das classes. O uso da DSL proporcionou uma visão mais ampla da regra de negócio e não exigiu conhecimento da linguagem de programação, pois o código foi gerado automaticamente.
