Full textAbstract:
In March 2000, 1 million litres of raw sewage was released into the water system of Maroochy Shire on Queensland’s sunshine coast. This environmental disaster was caused by a disgruntled ex-contractor using a radio transmitter to illicitly access the electronically controlled pumps in the control system. In 2007 CNN screened video footage of an experimental attack against a electrical generator. The attack caused the generator to shake and smoke, visually showing the damage caused by cyber attack. These attacks highlight the importance of securing the control systems which our critical infrastructures depend on. This thesis addresses securing control systems, focusing on securing the communications for supervisory control and data acquisition (SCADA) systems. We review the architectures of SCADA systems and produce a list of the system constraints that relate to securing these systems. With these constraints in mind, we survey both the existing work in information and SCADA security, observing the need to investigate further the problem of secure communications for SCADA systems. We then present risk modelling techniques, and model the risk in a simple SCADA system, using the ISM, a software tool for modelling information security risk. In modelling the risk, we verify the hypothesis that securing the communications channel is an essential part of an effective security strategy for SCADA systems. After looking at risk modelling, and establishing the value of securing communications, we move on to key management for SCADA systems. Appropriate key management techniques are a crucial part of secure communications, and form an important part of the contributions made in this work. We present a key management protocol that has been designed to run under the constraints specific to SCADA systems. A reductionist security proof is developed for a simplified version of the protocol, showing it is secure in the Bellare Rogaway model.

Full textAbstract:
The replacement of the Meat Act 1981 by the Animal Products Act 1999 opened a new era for food safety management in New Zealand. Administering food legislation is now the sole responsibility of the New Zealand Food Safety Authority instead of being shared between the Ministry of Agriculture and Forestry and the Ministry of Health as previously. At the core of the legislative change is the requirement for Risk Management Programmes (RMP). Every single animal primary processing business is required to have an RMP for each type of product. An RMP is required to embrace the principles of Hazard Analysis and Critical Control Point (HACCP). While there have been some studies considering the implementation of HACCP in food businesses worldwide, there has not been any study focusing on HACCP adoption in New Zealand. The mandating of RMP has also made the implementation process more complex. On the other hand, it also brings new experience in terms of food safety management. This thesis examines the implementation process of HACCP/RMP in New Zealand. It also explores the interaction between food safety management and international competitiveness through an economic analysis of the impacts of the program on a New Zealand food processing industry. The meat industry was chosen as a case study as it is one of the first industries that had to comply with the first deadline of the implementation (July 2003). Also, being a significant export-oriented industry of New Zealand, the meat industry provides an ideal case for the purpose of this study. The thesis consists of four parts. Part I presents an introduction to the study including a review of international and national food safety issues, the relationship between food safety and trade and international competitiveness, and the HACCP economic literature. This background helps to shape the research objectives and methodology as described in Chapter 3. Chapter 4 discusses the design of the survey to collect plant experience regarding the implementation of HACCP/RMP in New Zealand. Part II analyses the experiences within the New Zealand meat industry regarding the implementation of HACCP/RMP. It discusses plant motivations to adopt the program and the implementation issues they are facing. Plant observations on the costs and benefits of the implementation are reported. Further, data gathered from the survey are used in a non-parametric analysis of the influences of the plant characteristics on the HACCP/RMP implementation process. The analysis provides implications for HACCP/RMP policy design. Part III presents the modelling techniques to quantify the costs and benefits of HACCP/RMP implementation. In Chapter 8, a quality-adjusted cost function is used to estimate the change in variable cost of production due to HACCP/RMP. It shows that this type of cost can make up a significant proportion of the total implementation cost. In Chapter 9, an export model is employed to analyse the impact of HACCP/RMP on meat industry export performance. The results show that the programme can bring a positive impact on exports. However, the magnitude of the impact depends on the status of existing food safety management before HACCP/RMP implementation. In Chapter 10, the Global Trade Analysis Project (GTAP) model is used to simulate the scenarios where market accesses to significant export destinations are lost when HACCP/RMP is not adopted. The estimated costs of these losses signal the potential benefits of HACCP/RMP. The research results show that HACCP/RMP can deliver a net benefit to the New Zealand meat industry. The thesis concludes with implications for policy design and future research directions. It signifies that the research findings, in addition to reporting an investigation into HACCP/RMP implementation process in New Zealand, provide an important foundation for future research on food safety and international competitiveness.

Welsh, R. A. "Organisational diversity and HACCP enactment: A study of risk within the Australian food industry." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2009. https://ro.ecu.edu.au/theses/1902.
Full textAbstract:
This thesis examines the diversity management issues that arise from a risk management foray. It enters the organisational world and explores the social consequences of adopting a measure known as Hazard Analysis Critical Control Point or, to use the colloquial term, HACCP. Academically, it provides new knowledge on the tensions and discourse that mediate the response to the enactment. It links metatheory with the social mechanisms that operate within an organisation. It culminates with a theoretical model for the enactment of a HACCP program within a systems framework. Practically it contributes to the understanding of the diversity of applications of what may appear to be a simple measure but in practice has many dimensions.
The expectation behind adopting a risk management intervention is to embed internal controls that manage, rather than eliminate, risk within predefined limits. Conversely diversity is critical to maintaining organisational competitiveness. The management of diversity is a matter of increasing the types of model, methodology and theory as well as the mechanisms for choosing between those types. A strong focus on diversity is the antithesis of the control inherent in a risk management intervention. The presence of both within an organisation presents an interesting conundrum. This study focused on the tensions between a control focus arising from adopting a HACCP program and the need to promote diversity within as the organisation confronts the challenges of a rapidly changing market place.
This study took the unique opportunity to examine the enactment of a HACCP program from its inception as a legislative control tool to it becoming a mainstream assurance tool. It was serendipitous that enactment could be explored at a time of considerable market turbulence and where the effective use of diversity became critical to the survival of the organisation. The research design was based on the case study approach. It explored a series of cases over a tenyear period in an iterative manner. The study first looked at an industry as a whole as it struggled with seismic changes in legislation and market conditions. The focus progressively shifted more closely towards the organisation and its experiences, as it became more aware of the impact of new legislative forces. It culminated in a case study of an organisation that first evaluated then adopted a formal HACCP intervention based on the ISO22000 HACCP standard in response to market pressure. The study used interviews as the key research tool supported by observation and relevant documentation.
Each of the four study phases is reviewed in chronological order and culminates by Hazard Analysis Critical Control Point exposing the constructs that emerged across the cases and phases. The interpretation primarily focussed on actor perceptions to position the enactment of HACCP within organisation management discourse. A hermeneutic phenomenology approach was adopted to construct the interactions arising from the HACCP intervention. The constructs were clarified with the assistance of four established management theories.
The study found that rather than demonstrating uniformity of application the enactment of a HACCP program reflects the prevailing organisational interpretation of the meaning of management. The enactment partially defines the linkage between management practice and perceptions of power, politics, and conflict. It can also impact on the expression of performance. Finally, understanding comes from establishing a structural design in terms of HACCP focussed activity that strikes a balance between no structure and a superstructure. The balance is derived from the organisation’s own level of linkage with its social and technical environment.

The drink water production to human use with adequate standards is very important to the health of consumers. At present, there are many researches in development to value the treatment of water in the world with support of World Health Organization and Health Treasury. On this context, the HACCP system is a important instrument to maintain the quality in water production. The studied supply system was the ETA/UFV, where were value in microbiologic and physical-chemical aspects of all treatment points to value the hazards. About the results, the ETA was according with the decree MS no 518/2004. Still, were value the associations of the protozoan (oo)cysts with others aspects as spores (aerobic e anaerobic), heterotrophic plate count, Clostridium perfringens, turbidity, color and solids. In this value of the plan was possible to suggest to introduction the points of the HACCP in the water treatment, valuing the action of al the treatment point (raw water, sedimentation, filters, disinfection and distribution) and the removal of all parameters. With this work, it was suggest as critical points the raw water, sedimentation, filters and disinfection. However, the HACCP is a system to reduce the risks to the health, valuing all the points and locate the faults, so, it is important to consider the estimation necessity of each production unit, in this case the water treatment, carrying own assessment to locate the hazards in the production to establish own limits and preventions.
A produção de água para consumo humano com padrões adequados de potabilidade é de suma importância para a saúde da população consumidora. Atualmente, diversas pesquisas têm sido realizadas sob a sugestão da Organização Mundial de Saúde e Ministério da Saúde, no intuito de avaliar as técnicas disponíveis no tratamento de água e propor novas tecnologias e, ou novos parâmetros de qualidade. Nesse contexto, o sistema APPCC apresenta-se como ferramenta viável no controle da produção de água. O sistema de abastecimento em estudo foi o da Universidade Federal de Viçosa (SAA-UFV) onde foram monitoradas todas as etapas de tratamento segundo parâmetros microbiológicos e físico-químicos a fim de identificar os perigos a partir de um diagrama de fluxo pré-elaborado. Segundo os resultados obtidos, o controle da qualidade da água produzida pela esteve sempre de acordo com os padrões estabelecidos pela Portaria MS no 518/2004. Foi verificado, ainda, correlações significativas entre (oo)cistos de protozoários e os parâmetros esporos (aeróbios e anaeróbios), contagem de bactérias heterotróficas, Clostridium perfringens, turbidez, cor e sólidos em suspensão, sendo necessários, entretanto, outros estudos para a adequada validação desses resultados. A avaliação inicial da produção de água na estação de tratamento de água da UFV (ETA-UFV) permitiu subsidiar a aplicação dos princípios do APPCC. Segundo as remoções dos parâmetros microbiológicos e físico-químicos verificadas em cada etapa, foram considerados pontos de atenção: captação, decantação, filtração, desinfecção e distribuição. Como pontos críticos de controle, foram considerados: captação, decantação, filtração e desinfecção. Há ainda de se considerar que, sendo o APPCC um plano que busca minimizar as chances de falhas no sistema de produção a partir de avaliações sistemáticas do processo, é necessário que cada unidade de produção, neste caso, as estações de tratamento de água, realize estudos preliminares para verificação de seus perigos, pontos críticos e medidas próprias de prevenção e, ou, controle.

Full textAbstract:
Despite the existence of extensive literature regarding risk management, there still seems to be lack of knowledge in identification of Critical Success Factors (CSFs) in this area. In this research Grounded Theory is implemented to identify CSFs in Risk Management Systems (RMS). Factor analysis and one-sample t-test are then used to refine and rank the CSFs based on the results of a survey which has been performed among Risk Management practitioners in various types of Swedish corporations. CSFs are defined from three different perspectives: (a) the factors that have influence on the inclination and readiness of corporation for implementing RMS. (b) the factors that are important during the design and implementation of RMS in corporation and can significantly affect the success of RMS design and implementation and (c) the factors that are crucially important to successfully run, maintain and administrate RMS after the closure of the project of RMS design and Implementation.
This systematic approach towards understanding the taxonomy of the success dimension in RMS is important for re-enforcing effective risk management practices.

Full textAbstract:
Forward planning and risk management are crucial for the success of any system or business dealing with the uncertainties of the real world. Previous approaches have largely assumed that the future will be similar to the past, or used simple forecasting techniques based on ad-hoc models. Improving solutions requires better projection of future events, and necessitates robust forward planning techniques that consider forecasting inaccuracies. This work advocates risk management through optimal control theory, and proposes several techniques to combine it with time-series forecasting. Focusing on applications in foreign exchange (FX) and battery energy storage systems (BESS), the contributions of this thesis are three-fold. First, a short-term risk management system for FX dealers is formulated as a stochastic model predictive control (SMPC) problem in which the optimal risk-cost profiles are obtained through dynamic control of the dealers’ positions on the spot market. Second, grammatical evolution (GE) is used to automate non-linear time-series model selection, validation, and forecasting. Third, a novel measure for evaluating forecasting models, as a part of the predictive model in finite horizon optimal control applications, is proposed. Using both synthetic and historical data, the proposed techniques were validated and benchmarked. It was shown that the stochastic FX risk management system exhibits better risk management on a risk-cost Pareto frontier compared to rule-based hedging strategies, with up to 44.7% lower cost for the same level of risk. Similarly, for a real-world BESS application, it was demonstrated that the GE optimised forecasting models outperformed other prediction models by at least 9%, improving the overall peak shaving capacity of the system to 57.6%.

Full textAbstract:
The aim of this thesis is to use qualitative research to investigate and analyse how human resource risks are understood and managed in practice and how to efficiently manage HR risk in a cost effective way. The research – adding to a very limited corpus in the literature – was conducted in public sector organisations in the UK. The author argues that HR risk management should be conducted in a systematic way. The Managing HR risk framework proposed in this thesis could be used as a practical guide to enable HR practitioners to manage HR risk more effectively. The thesis finds that, in order to effectively manage HR risk, a culture change is required at both HR department and organisational level; the prevailing risk averse culture should change to a more flexible, strategically-focused and less formalised process. From the analysis of case studies, the author notes that HR practitioners should be aware of their position in a HR conflict; they need to be neutral, fair, and supportive during the process of managing HR risks. It is concluded that qualitative factors will influence the process of managing HR risk such as power, organisational culture, management style and skills/competencies… It further suggested that organisational isomorphism learning enables organisations to learn from past experiences, and to improve HR risk management. It also recommended that simulations offer an excellent vehicle for improving the process of managing HR risk by equipping HR practitioners with the right skills and experience. Through the analysis of the results of interviews, two valuable case studies, and simulation, this thesis offers new directions for the future research of human resource risk management: Simulation could be used to help HR practitioners to improve the ways of managing HR risk, simulation use real-life cases for training to improve players’ or decision makers’ understanding of holistic events, and apply new skills, attitudes in practice.

Full textAbstract:
Traditional methods of project management are not appropriate for complex projects anymore. Since projects are becoming increasingly complex and uncertain, interaction between activities and resources is growing in ways not considered by these methods. Nowadays, managers need more agile project management methods that are able to recognize and deal with uncertainty and to produce the expected results. Lean project management, the most recent approach of lean methodology, appears as an alternative approach capable of dealing with complexity and uncertainty. The latest investigations in the field show that traditional methods are still adequate for simple projects, while lean methods are more appropriate for complex projects. This thesis aims to investigate the nature of lean project management and to examine project risk management processes so that managers can assess the complexity of projects before their beginning and decide which method to apply in order to manage them.

Full textAbstract:
This dissertation explores regulation’s influence on risk management and management control systems (MCS) in banks. The dissertation comprises of an introductory chapter, two published book chapters, one of which is an extensive literature review, and two working papers, presented at several European conferences. The overall objective of this dissertation is to explore how banks are responding to banking regulation in light of the 2007-08 financial crisis and what the implications of those responses are, particularly in relation to risk management and MCS, and their interactions. The overall research question is therefore: what influence does regulation have on risk management and management control systems in banks over time? The intended ambition is to contribute to existing knowledge on the relationship between bank regulation, risk management, and MCS by providing several practical and theoretical contributions. The dissertation employs an adapted theoretical framework and uses institutional theory and contingency theory to expose tensions between, the demands for uniformity residing in banking regulation, and the demands for uniqueness residing inside banks themselves as they seek to maintain control over the design and use of their organizational controls. The empirical material used in the longitudinal case study is gathered from a large European bank. The main findings of the dissertation are as follows. In Paper I, the findings show that banking regulation’s influence on risk management and management control is mixed, which in turn can influence risk management’s integration with MCS. The paper also finds that very little knowledge exists about regulation’s influence on risk management and MCS. In Paper II, the findings show that while regulatory influence in IT control has increased over time, banks continue to exercise significant influence over regulatory demands. In Paper III, the findings show how regulation’s influence varies considerably over time and that increased regulatory pressure can lead to a higher degree of integration between risk management and MCS across the three dimensions of integration. In Paper IV, the findings show how regulation’s influence is shaping the mental processes of management and employees, and can vary significantly based on several identified factors.

Full textAbstract:
The goal of this research is to critically examine the nexus of risk management, decision-making, and knowledge management in an integrated framework, or triad. This research will examine this framework through the lens of managers in both human and scientific spaceflight missions at the National Aeronautics and Space Administration (NASA). It is intended to expose how coupling risk, knowledge and decision-making improve chances for mission success while potentially averting mishaps. Historical case studies of NASA Programs will be used to validate this assertion. Common risk management and knowledge management processes will be examined as enablers for risk-informed decision-making, particularly for residual risk acceptance decisions. Decision-making under normal programmatic conditions as well as during anomalous or mishap-related conditions will also be assessed.
Residual risk acceptance decision-making might be considered a special case of a requisite decision analysis model. In the context of NASA programs and projects these decisions are made throughout the lifecycle. They take on special significance however in the context of human spaceflight missions such as whether to: proceed with human-tended test and evaluation, to launch, or to respond to an off-nominal condition on-orbit. Finally, this dissertation offers a checklist for use by managers to improve residual risk acceptance decision competency within an organization.

In today’s world, project risk management has always been a complex topic, especially inconstruction industry; thus managing project risks is required as compulsory for anyconstruction project to be successful. This master thesis presents a critical analysis ofproject risk management and significant impacts of its application on the success of aspecific project’s delivery. It identifies different types of project risk managementprocesses and frameworks used by construction projects. In order to examine how risk andrisk management process is perceived in construction projects, a case study of a LeheHome reconstruction project is chosen and data collection methods of semi-structuredinterviews and questionnaires are applied. The main purpose of this thesis is to explore,describe and analyze the perceived risk management practice in Lehe Home reconstructionproject. Managing risks in Lehe Home project has been recognised as a very importantproject management process in order to achieve the project objectives in terms of time,cost, quality. The study will examine and evaluate the risk management process in specificphases of Lehe Home project and essentially analyze the empirical findings. Finally, thestudy generalizes and develops the project risk analysis and management from Lehe Homeproject and suggests for public sectors to help project managers to make better decisionsunder risky conditions.

Full textAbstract:
Many satellites have an orbit of reference defined according to their mission. The satellites need therefore to navigate as close as possible to their reference orbit. However, due to external forces, the trajectory of a satellite is disturbed and actions need to be taken. For now, the trajectories of the satellites are monitored by the operations of satellites department which gives appropriate instructions of navigation to the satellites. These steps require a certain amount of time and involvement which could be used for other purposes. A solution could be to make the satellites autonomous. The satellites would take their own decisions depending on their trajectory. The navigation control would be therefore much more efficient, precise and quicker. Besides, the autonomous orbit control could be coupled with an avoidance collision risk management. The satellites would decide themselves if an avoidance maneuver needs to be considered. The alerts of collisions would be given by the ground segment. In order to advance in this progress, this internship enables to analyse the feasibility of the implementation of the two concepts by testing them on an experiments satellite. To do so, tests plans were defined, tests procedures were executed and post-treatment tools were developed for analysing the results of the tests. Critical computational cases were considered as well. The tests were executed in real operations conditions.Många satelliter har en referensbana definierad enligt deras uppdrag. Satelliterna behöver därför navigera så nära deras referensbana som möjligt. På grund av externa krafter störs dock satellitbanan och åtgärder måste vidtas. För närvarande övervakas satellitbanorna av satellitavdelningar på marken vilka ger lämpliga instruktioner för navigering till satelliterna. Dessa steg kräver en tid och engagemang som skulle kunna användas för andra ändamål. En lösning är att göra satelliterna autonoma. Satelliterna skulle då kunna ta sina egna beslut beroende på deras bana. Navigeringskontrollen skulle därför vara mycket mer effektiv, exakt och snabbare. Dessutom kan den autonoma banregleringen kopplas till riskhantering för undvikande av kollision med rymdskrot och andra satelliter. Satelliterna skulle själva avgöra om en undvikande manöver måste övervägas. Varningar om kollisioner skulle ges av marksegmentet. För att gå vidare i denna utveckling analyserar detta arbete genomförbarheten av implementeringen av olika koncept för undanmanövrar genom att testa dem på en experimentsatellit. För att göra detta definierades testplaner, testprocedurer utfördes och efterbehandlingsverktyg utvecklades för analys av testresultaten. Kritiska beräkningsfall togs fram. Testerna utfördes under verkliga driftsförhållanden.

In the nuclear, aerospace and chemical industries, the need for risk management is straightforward. When a system failure mode may cause a very high cost in lives or economic value, risk management becomes a necessity. In its short history, Information Technology (IT) came to be a crucial part and sometimes the platform of business activities for many large companies such as telecommunication or financial services organizations. However, due to scale and complexity, risk management methods used by other industries are not widely applied in IT.In this thesis, we investigate how probabilistic risk assessments methods used in other industries can be applied to IT network environments. A comparison is done using a number of possible approaches, improvements to these approaches are suggested, and different tradeoffs are discussed. The thesis examines ways to apply probabilistic risk assessment to a Service Oriented Architecture environment (where each service is an application or a business process that depends on other services, local and networked resources) to estimate the service reliability, availability, expected costs over time and the importance measures of elements and configurations. Finally, a method of performing cost benefit analysis is presented to estimate the implication of changing the services-supporting infrastructure, while taking into consideration the varying impact of different services to the business.A case study is used to demonstrate the methods suggested in the thesis. The case study compares four different configurations, showing how equipment failure and human error can be placed into a single framework and addressed as a single system. The implications and application of the results are discussed and recommendations for further research are provided.

Full textAbstract:
This study reviews ship security assessment. The objectives are to explore the possibilities for quantifying and performing a more thorough ship security risk analysis than that described in the International Ship and Port Facility Security code and to evaluate to what extent this more detailed analysis increases ship security and facilitate the effective selection of risk control options. The study focuses on Somali-based maritime piracy, using piracy on the Indian Ocean as a case study. Data are collected using questionnaires and interviews with civilian and military security experts who possess firsthand experience of piracy off the coast of Somalia. The data are collected specifically for this study and describe and quantify the threat’s capability, intent and likelihood of exploiting a ship’s vulnerability. Based on the collected description of the threat, the study analyzes and describes: probability of detection by pirates, probability of successful approach, and probability of successful boarding. The performed work shows good agreement between calculated probabilities and frequencies in the cited incident reports. Also, the developed scenarios describe the most important influences on the analyzed areas. The research therefore shows that the proposed risk-based approach, which uses structurally collected and documented information on the threat, can increase ship security by assisting in selecting risk control options. The approach also allows for a better understanding of the causal relationship between threat and risk than that provided in today’s security analysis by ship owners, for example. This understanding is crucial to choosing effective and robust risk control options.

Full textAbstract:
A leader's unwillingness to delegate critical decision-making authority to subordinate managers and employees negatively impacts the performance of a firm. There is a lack of research that measures a leader's willingness to delegate critical decision-making authority to subordinate managers and employees based on their individual risk propensities. The purpose of this study was to provide empirical evidence of the influence risk propensity has on a leader's willingness to delegate critical decision-making authority. Specifically, this study examined the extent that risk propensity of leaders affect delegating critical decision making authority to subordinate managers and employees. The research design was a quantitative cross-sectional, correlation study that involved 56 questions. The study participants (N = 102) were presidents, CEOs, corporate executives, and chairpersons. The Stimulating-Instrumental Risk Inventory measured risk propensity and the Delegation Decision Instrument measured the willingness delegate critical decision-making authority. Both instruments showed to be reliable in terms of internal consistency for the measurement tests. Survey results revealed a significant negative correlation between a leader's risk propensity and the willingness to delegate critical decision-making authority. These findings suggested that leaders who retain primary responsibility for critical decision making have high risk propensity while those who delegate decisions have less risk propensity. These findings may equip theorists of risk propensity and decision-making on the relationship between delegation behaviors, risk propensity, and organizational performance. This research and the resulting analysis provides decision makers a window into their individual risk propensity preferences.

Network revenue management is the practice of using optimal decision policies to increase revenues by controlling limited quantities of multiple resources' availability and prices over finite time. It is widely practiced in capacity-constrained service industries such as the airlines, hotels, car rentals, and cruise-lines. A variety of control methods has been introduced for network resource capacity control problem. We propose a clustering method to improve approximation quality. By clustering the legs of the network, one can find tighter upperbound than leg-wise decomposition with loss of computation speed due to larger state space. We have shown that there is more than 6% revenue improvement opportunity by finding the right clustering. With local interchange heuristic and generic heuristics, finding a locally optimal clustering can be done in faster time. We also introduce risk-aversion in network revenue management. We have investigated risk-aversion on network revenue management and also study the impact of risk-aversion parameters in the optimization model on relative revenue-risk performance.

Full textAbstract:
The aim of this research was to improve the quantitative support to project planning and control principally through the use of more accurate forecasting for which new techniques were developed. This study arose from the observation that in most cases construction project forecasts were based on a methodology (c.1980) which relied on the DHSS cumulative cubic cost model and network based risk analysis (PERT). The former of these, in particular, imposes severe limitations which this study overcomes. Three areas of study were identified, namely growth curve forecasting, risk analysis and the interface of these quantitative techniques with project management. These fields have been used as a basis for the research programme. In order to give a sound basis for the research, industrial support was sought. This resulted in both the acquisition of cost profiles for a large number of projects and the opportunity to validate practical implementation. The outcome of this research project was deemed successful both in theory and practice. The new forecasting theory was shown to give major reductions in projection errors. The integration of the new predictive and risk analysis technologies with management principles, allowed the development of a viable software management aid which fills an acknowledged gap in current technology.

Full textAbstract:
Setting against the significant background of Industrial 4.0, the Industrial Control System (ICS) accelerates and enriches the upgrade the existing production infrastructure. To make the infrastructures “smart”, huge parts of manual operations have been automated in this upgrade and more importantly, the isolated controlled processes have been connected through ICS. This has also raised the issues in asset management and security concerns. Being the starting point of securing the ICS, the asset identification is, nevertheless, first dealt by exploring the definition of assets in the ICS domain due to insufficient documentation and followed by the introduction of ICS constituents and their statuses in the whole network. When the definition is clear, a well-received categorization of assets in the ICS domain is introduced, while mapping out their important attributes and their significance relating the core of service they perform. To effectively tackle the ever-increasing amount of assets, identification approaches are compared and a case study was performed to test the effectiveness of two open source software. Apart from the identification part, this thesis describes a framework for efficient asset management from CRR. The four cyclic modules proposed give an overview on how the asset management should be managed according the dynamics of the assets in the production environment.

Quality management in higher education is a politically contentious issue in Australia. as it is in North America, New Zealand, and many European countries. The Australian government has instituted a quality management system for higher education that it claims will improve university efficiency, accountability and quality. Critics assert that the current quality management system is detrimental to universities and undermines the capability of universities to deliver maximal benefits to individuals and to society. Evaluation of the basis of conflicting claims is necessary to enable decisions about the usefulness of current practices and decisions about whether existing quality management arrangements should be retained, modified and developed, or replaced, or, abolished.

The world of today is increasingly dependant on a functional, globalized economy.
The defence and security establishments’ reliance on supplies and logistics is not new. First responders rely on many tools and systems that are critical to their endeavours. Somewhat disjoint at first glance, these domains share a common need for complex physical or logistical infrastructures such as power plants, ports, supply chains, to name a few examples.All of these are potentially vulnerable to attacks, disruptions, breakdowns, or other activities that disable the infrastructure and consequently cause important physical or economic damage. An obligation exists to protect these critical infrastructures and a decision support system that is able to detect, identify, and mitigate the risk of unwanted events would be invaluable in preventing the disastrous consequences of compromised infrastructure.This thesis explores the design and application of such a system. It starts with a pre-existing, actively researched risk management framework and proposes a methodology to apply it in new contexts, as well as contributions to provide the framework with the ability to solve new problems. Relevant case studies in critical infrastructure protection are presented, as well as applications of the developed methodology with the proposed modifications when suitable. Simulations, results, and insightful discussions are provided for each of the case studies. Finally, research trends, future work, and a conclusion are given, completing this thesis.

Full textAbstract:
This research has first reviewed the current status and future aspects of marine and offshore safety assessment. The major problems identified in marine and offshore safety assessment in this research are associated with inappropriate treatment of uncertainty in data and human error issues during the modelling process. Following the identification of the research needs, this thesis has developed several analytical models for the safety assessment of marine and offshore systems/units. Such models can be effectively integrated into a risk-based framework using the marine formal safety assessment and offshore safety case concepts. Bayesian network (BN) and fuzzy logic (FL) approaches applicable to marine and offshore safety assessment have been proposed for systematically and effectively addressing uncertainty due to randomness and vagueness in data respectively. BN test cases for both a ship evacuation process and a collision scenario between the shuttle tanker and Floating, Production, Storage and Offloading unit (FPSO) have been produced within a cause-effect domain in which Bayes' theorem is the focal mechanism of inference processing. The proposed FL model incorporating fuzzy set theory and an evidential reasoning synthesis has been demonstrated on the FPSO-shuttle tanker collision scenario. The FL and BN models have been combined via mass assignment theory into a fuzzy-Bayesian network (FBN) in which the advantages of both are incorporated. This FBN model has then been demonstrated by addressing human error issues in a ship evacuation study using performance-shaping factors. It is concluded that the developed FL, BN and FBN models provide a flexible and transparent way of improving safety knowledge, assessments and practices in the marine and offshore applications. The outcomes have the potential to facilitate the decision-making process in a risk-based framework. Finally, the results of the research are summarised and areas where further research is required to improve the developed methodologies are outlined.

Full textAbstract:
Current models that assess infrastructure failure risk are â linear,â and therefore, only consider the direct influence attributed to each factor that defines risk. These models do not consider the undeniable relationships that exist among these parameters. In reality, factors that define risk are interdependent and influence each other in a â non-linearâ fashion through feedback effects. Current infrastructure failure risk assessment models are also static, and do not allow infrastructure managers and decision makers to evaluate the impacts over time, especially the long-term impact of risk mitigation actions. Factors that define infrastructure failure risk are in constant change.
In a strategic manner, this research proposes a new risk-based infrastructure management framework and supporting system, Risk-Based Dynamic Infrastructure Management System (RiskDIMS), which moves from linear to non-linear risk assessment by applying systems engineering methods and analogs developed to address non-linear complex problems. The approach suggests dynamically integrating principal factors that define infrastructure failure risk using a unique platform that leverages Geospatial Information System services and extensions in an unprecedented manner. RiskDIMS is expected to produce results that are often counterintuitive and unexpected, but aligned to our complex reality, suggesting that the combination of geospatial and temporal analyses is required for sustainable risk-based decision making. To better illustrate the value added of temporal analysis in risk assessment, this study also develops and implements a non-linear dynamic model to simulate the behavior over time of infrastructure failure risk associated with an existing network of levees in New Orleans due to diverse infrastructure management investments. Although, the framework and RiskDIMS are discussed here in the context of levees, the concept applies to other critical infrastructure assets and systems. This research aims to become the foundation for future risk analysis system implementation.Master of Science

Thesis (MBA)--Stellenbosch University, 2012.Governance Risk and Compliance (GRC) software applications are designed to facilitate the GRC process. GRC software inherently faces the same implementation challenges as any other Enterprise Resource Planning (ERP) software. The design and usability of GRC software contribute substantially to how much value is added to the GRC process and as GRC is still in its infancy; it is likely to keep evolving as this process matures. Due to the inconstant nature of the GRC process, GRC software applications require a large amount of customisation to meet the special requirements of each organisation. The objective of this research was to establish the extent to which GRC software applications add value to the GRC process. The researcher also tried to establish whether organisations, that are currently using GRC software applications, gain more value from the GRC process than before they implemented GRC software applications. He conducted the research by presenting research questions, in the form of a questionnaire, to the risk executives of three Western Cape companies. The author of this research paper collected the responses from each company by conducting one-on-one interviews with each of the executives concerned and then reviewed and analysed the interview results of each company. Finally, the author completed a cross case analysis, by comparing GRC software application dimensions and characteristic ratings across the three companies concerned. The research indicated that there is not a great difference in importance between the five GRC design dimensions because they all received high performance ratings. There were some differences, however, in the perceived performance of each dimension, when analysing the dimension characteristics ratings. The research showed that the greatest benefit, of the use of GRC software applications, is the ability to add structure and consistency to the GRC process.

Full textAbstract:
Critical Infrastructure Industrial Control Systems are substantially different from their more common and ubiquitous information technology system counterparts. Industrial control systems, such as distributed control systems and supervisory control and data acquisition systems that are used for controlling the power grid, were not originally designed with security in mind. Geographically dispersed distribution, an unfortunate reliance on legacy systems and stringent availability requirements raise significant cybersecurity concerns regarding electric reliability while constricting the feasibility of many security controls. Recent North American Electric Reliability Corporation Critical Infrastructure Protection standards heavily emphasize cybersecurity concerns and specifically require entities to categorize and identify their Bulk Electric System cyber systems; and, have periodic vulnerability assessments performed on those systems. These concerns have produced an increase in the need for more Critical Infrastructure Industrial Control Systems specific cybersecurity research. Industry stakeholders have embraced the development of a large-scale test environment through the Department of Energy’s National Supervisory Control and Data Acquisition Test-bed program; however, few individuals have access to this program. This research developed a physical industrial control system test-bed on a smaller-scale that provided an environment for modeling a simulated critical infrastructure sector performing a set of automated processes for the purpose of exploring solutions and studying concepts related to compromising control systems by way of process-tampering through code exploitation, as well as, the ability to passively and subsequently identify any risks resulting from such an event. Relative to the specific step being performed within a production cycle, at a moment in time when sensory data samples were captured and analyzed, it was possible to determine the probability of a real-time risk to a mock Critical Infrastructure Industrial Control System by comparing the sample values to those derived from a previously established baseline. This research achieved such a goal by implementing a passive, spatial and task-based segregated sensor network, running in parallel to the active control system process for monitoring and detecting risk, and effectively identified a real-time risk probability within a Critical Infrastructure Industrial Control System Test-bed. The practicality of this research ranges from determining on-demand real-time risk probabilities during an automated process, to employing baseline monitoring techniques for discovering systems, or components thereof, exploited along the supply chain.

Full textAbstract:
This thesis uses a new institutional sociology perspective to examine financial risk management practices adopted by Saudi listed companies and identify the factors that influence these practices. In Islamic shariah law, using conventional derivatives is prohibited and so this thesis aims to determine if there is an institutional logic within the organisational field and a community of practice that results from networks of actors. The study also, examines the effect of different types of coercive, mimetic and normative isomorphic pressures on the adoption of risk management practices by Saudi listed companies. For this purpose, two pieces of empirical work are employed, (i) semi- structured interviews; and (ii) statistical tests. The interviews were held with 22 treasury managers of Saudi listed companies in 2011 to explore their perspectives of financial risk management practices. The second empirical work uses binary logistic regression to test the factors that might affect the adoption of financial risk management practices of 132 listed companies using publicly available data in 2011. Most of the previous studies relating to financial risk management practices have been undertaken in developing countries Therefore, there is a need to expand the scope of existing research by investigating such practices in Islamic countries to test the relevance of existing theory there and to enrich the risk financial management literature. This thesis investigate 12 factors: (the influence of political factors, cultural factors, and the competitive environment in Saudi society as well as nine institutional characteristics, comprising: firm size; profitability; leverage; being an Islamic company; auditor type; industrial sector; ownership structure; number of subsidiaries and exports) to identify to what extent they affect the financial risk management practices in the organisational field. The main findings indicate that Saudi listed companies hedge more interest rate risk than other financial risks, using conventional derivatives contracts which are prohibited in Islam. This finding is surprising in a country such as Saudi Arabia that is regulated and dominated by Shariah law. The political, cultural and competitive environments also affect the financial risk management practices in the organisational field. In addition, firm size in Saudi Arabia is related to interest rate risk and foreign exchange rate risk; also more leveraged companies and companies audited by Big-4 firms hedge interest rate risk. In addition, Islamic companies depend on Islamic derivatives that are available to hedge financial risk. Furthermore, the profitability of companies, industrial sector and their ownership structure has little influence on the risk management practices in Saudi listed companies. Finally, having subsidiaries and exports also affects hedging practices. It seems that actors are involved in similar networks and that considerable boundary-spanning takes place across these networks especially by treasury managers. This results in several different communities of practice with different organisational logics.

Full textAbstract:
This thesis concerns the introduction of a Western idea of risk management to a peripheral control system as it examines the unintended consequences of re-embedding Enterprise Risk Management (ERM) in an Egyptian insurance company. It traces how ERM was introduced, constructed, modified, and re-defined over time, causing institutional complexity, heterogenic practices, and identity crisis. It ultimately seeks to understand how a new form of management control was made operable amidst local resistance. The research involved intensive fieldwork with in-depth interviews, direct observations, and documentation reviews. Drawing on institutional logics and Egypt’s geopolitical ramifications, it illustrates how Risk Based Management Control (RBMC) was introduced by Western agencies, how this new control system caused logics competition, and how some ambiguities in identities consequently developed. It was the emergence of the Arab Spring that negatively reacted to those pressures, resulting in great resistance that was amplified through a clash of civilizations as a proper communal understanding and action after the country’s revolutions, which this work calls a “geopolitical shield”. This analysis makes three contributions to RBMC and logics. First, it extends the institutional logics debate by illustrating that logics get re-institutionalized by the “place” through its cultural and communal identities that filter logic complexities to different ends. Secondly, it extends the cultural political economy of management accounting by illustrating that management accounting in less developed countries (LDCs) is also an operational manifestation of the geopolitics of locale, location, and place. Finally, it provides an illustrative critique for implementing RBMC systems, which in the West were previously cascaded to operational arenas successfully, as other researchers reported, but in the current case this cascading is disrupted by the geopolitical shield activation. Shield activation at the micro level not only successfully hindered RBMC and its apparatuses but also protected monologic controls from becoming heterogenic.
