La Quantitative Risk Analysis costituisce un valido strumento per la determinazione del rischio associato ad un’installazione industriale e per la successiva attuazione di piani di emergenza. Tuttavia, la sua applicazione nella progettazione di un lay-out richiede la scelta di un criterio in grado di valutare quale sia la disposizione ottimale al fine di minimizzare il rischio. In tal senso, le numerose procedure esistenti, sebbene efficaci, risultano piuttosto faticose e time-consuming. Nel presente lavoro viene dunque proposto un criterio semplice ed oggettivo per comparare i risultati di QRA applicate a differenti designs. Valutando l’area racchiusa nelle curve iso-rischio, vengono confrontate dapprima le metodologie esistenti per lo studio dell’effetto domino, e successivamente, viene applicata al caso di serbatoi in pressione una procedura integrata di Quantitative Risk Domino Assessment. I risultati ottenuti dimostrano chiaramente come sia possibile ridurre notevolmente il rischio di un’attività industriale agendo sulla disposizione delle apparecchiature, con l’obiettivo di limitare gli effetti di possibili scenari accidentali.

A challenging yet crucial component of emergency planning is to identify relevant hazards and assess their risk level. Within the Province of Ontario, Canada, governmental emergency management stakeholders are required to use the Hazard Identification and Risk Assessment (HIRA) process, developed by the Province, to meet legislative compliance. The HIRA process is based on the use of risk matrices and hence faces many of the inherent challenges of this method, potentially resulting in a poor risk assessment process with a low quality outcome. The aim of this thesis is to analyze Ontario’s Provincial HIRA process to identify weaknesses, strengths, and gaps, in order to increase understanding for potential issues related to this type of hazard identification and risk assessment process within emergency preparedness. The Provincial HIRA process will be analyzed, as it is implemented in the Regional Municipality of York, including the Public Health Unit, by comparing the process to six points identified in the literature as potential challenges with the ability to compromise the quality of a risk assessment process. The main focus is on the use of risk matrices although some aspects more generally related to risk assessments have been included. Overall the Provincial HIRA has several weaknesses and gaps. It is evident that the process demonstrates many of the issues that impair the quality of risk assessments supported by the use of risk matrices such as ambiguous input and out-puts, errors, poor resolution and sub-optimal resource allocation. Additionally, a significant amount of resources and access to hazard subject matter expertise would be required to execute the HIRA in accordance with the guideline. Such resources are not necessarily available to the target audience. All these aspects contribute to a risk assessment process that struggles to meet one of its main objectives, to provide the user with a quantitative risk ranking with the capacity to distinguish between risk levels of different hazards. Subsequently the outcome may not accurately support the emergency planning or the decision making process related to resource allocation.Identifiering av lokalt relevanta faror och bedömning av deras risknivåer är en kritisk och komplex del av arbetsområdet beredskap för nödsituationer (eng. emergency preparedness). Myndigheter som bedriver verksamhet inom detta område i provinsen Ontario, Kanada är enligt lag skyldiga att genomföra en ”Hazard Identification and Risk Assessment” (HIRA) process, utvecklad av provinsen. HIRA-metoden är baserad på användandet av risk matriser och står således inför många av denna metods inneboende utmaningar vilket kan resultera i svag riskbedömningsprocess med tvivelaktigt resultat. Syftet med denna uppsats är att analysera Ontarios HIRA-process för att identifiera potentialla svagheter, styrkor och luckor i processen och således generera insikt i potentiella utmaningar relaterat till denna typ av riskbedömningsprocess inom ”emergency preparedness”. HIRA-processen, så som den implementerats i York Region och inom dess folkhälsomyndighet, kommer att analyseras baserat på sex punkter identifierade inom litteraturen som aspekter med förmåga att påverka kvalitén på riskdömningsresultatet. Sammanfattningsvis ses att HIRA-processen innefattar många av de svagheter som diskuteras i litteraturen rörande riskmatriser som till exempel fel, tvetydig in- och utdata, dålig upplösning och suboptimal resursfördelning vilket potentiellt medför en riskbedömningsprocess av låg kvalité. För att genomföra HIRA-processen så som metoden är designad behöver användaren investera en betydande mängd resurser samt helst tillgå expertis inom riskbedömning relaterat till de olika farorna som skall bedömas, vilket inte alltid finns tillgängligt inom de organisationen som genomför en HIRA. Dessa aspekter sammantaget bidrar till en process som inte nödvändigtvis når fram till ett av sina primära mål; att skapa en kvantitativ rangordning av risker med förmåga att särskilja olika farors risknivå. Till följd finns en risk att resultatet av riskbedömning inte stödjer den operativa planeringen eller processen för beslutsfattande relaterad till resursfördelning.

An increasing emphasis on chemical process safety over the last two decades has led to the development and application of powerful risk assessment tools. Hazard analysis and risk evaluation techniques have developed to the point where quantitatively meaningful risks can be calculated for processes and plants. However, the results are typically presented in semi-quantitative âÂÂranked listâ or âÂÂcategorical matrixâ formats, which are certainly useful but not optimal for making business decisions. A relatively new technique for performing valuation under uncertainty, Value at Risk (VaR), has been developed in the financial world. VaR is a method of evaluating the probability of a gain or loss by a complex venture, by examining the stochastic behavior of its components. We believe that combining quantitative risk assessment techniques with VaR concepts will bridge the gap between engineers and scientists who determine process risk and business leaders and policy makers who evaluate, manage, or regulate risk. We present a few basic examples of the application of VaR to hazard analysis in the chemical process industry. We discover that by using the VaR tool we are able to present data that allows management to make better informed decisions.

Risk can be described as the absence of information when a decision is to be made at any time throughout a process. The construction industry is often considered as complex and defragmented due to working in a project based format; with a unique product and a process where there are times when decisions need to be made with insufficient information. Therefore, proper risk management processes can be vital to minimizing risks, maximizing opportunities and securing a successful project process. This master thesis has been conducted at a large Swedish construction company that houses both a constructing unit and a residential development unit. Consequently, the focus of this thesis has been on analyzing the risk management process when a residential project is both developed and constructed by the same company. The purpose of this master thesis is to describe and analyze risk management in a project based organization within the construction industry. The thesis aims to provide a better understanding of how risk management is used in practice but also what underlying factors that can affect risk management processes. The study will include both the perspective of the developer and the constructor; as well as their separate and joint processes facilitating risk management. In regards to the purpose of this thesis, a general risk management model has been used to provide a framework for analysis. This model consists of four steps: risk identification, risk assessment, risk mitigation and risk monitoring. The results from this study indicate that risk management within residential construction heavily depends on the personal knowledge and experience of project members. In turn, this creates discrepancies between how risk management is described in internal documents and how it is utilized in practice. Furthermore, it was found that risk management is considered an important part of the overall project process. However, opinions varied to what extent risk management was actually applied in projects. A reason for this could be that there is no joint understanding within the company of what processes are considered as part of risk management – thus, project members sometimes practice risk management without being aware of it.Risk kan definieras som avsaknaden av information när ett beslut måste tas, vid något tillfälle, under en pågående process. Byggindustrin anses ofta vara en komplex och splittrad bransch då man arbetar i projektformat och med en komplicerad slutprodukt, vilket skapar otaliga tillfällen när beslut måste fattas med otillräcklig information. Därför är en väl fungerande riskhanteringsprocess viktig för att minimera risker, maximera möjligheter och säkerställa lyckade projekt. Detta examensarbete har genomförts på ett av de större svenska byggbolagen som har både bostadsutveckling och entreprenad inom den egna verksamheten. Därmed kommer detta examensarbete att fokusera på riskhanteringsprocessen inom bostadsbyggande då ett och samma företag agerar som både beställare och byggare. Syftet med detta examensarbete är att beskriva och analysera riskhanteringsprocessen inom ett projektbaserat företag i byggbranschen. Uppsatsen har som mål att skapa en bättre förståelse för hur riskhantering används i praktiken, samt för de underliggande faktorer som påverkar riskhantering. Studien kommer att inkludera både beställarens och byggarens perspektiv, samt deras respektive, och gemensamma, processer i relation till riskhantering. Med hänseende till studiens syfte har en generell modell för riskhantering använts för att ge ett ramverk till analysen. Denna modell består av fyra steg: riskidentifiering, riskvärdering, riskhantering och riskuppföljning. Studien visar på att riskhantering inom bostadsbyggande till stor del grundar sig på projektmedlemmarnas personliga kunskap och erfarenhet. Detta leder till att det finns skillnader mellan den avsedda processen för riskhantering och hur riskhanteringsarbetet faktiskt genomförs. Vidare fann studien att riskhantering ansågs vara en viktig del av projektprocessen i sin helhet. Trots detta varierade åsikter kring hur riskhantering faktiskt genomfördes i projekt. En anledning till detta kan vara att det inte finns någon gemensam syn på vilka processer som faktiskt ingår i riskhanteringsarbetet – detta innebär i sin tur att projektmedlemmar ibland bedriver riskhantering utan att vara medvetna om det.

Many products that we see in our daily life are designed through modifications to existing products. The ever changing trends in current markets, along with customers' rising demands for quality, require many companies to make frequent changes to create new products. Due to the challenges in product modification, many companies have adopted a strategy of adaptive design to create new designs by incrementally improving the existing ones. This thesis develops a decision support system which helps product development managers to assess project performance metrics, such as development effort, development time, product cost and revenue, customer satisfaction, profit margin, and risk. The proposed model is a specialized calculator which integrates house of quality (HOQ), functional analysis system technique (FAST), risk assessment, product complexity analysis, and change propagation analysis to provide an overview of the design process from product attributes and design risk to cost and effort.The assessment of different design solutions is performed by comparing the obtained performance metrics with those from the original design. The system allows the recalculation of these performance metrics when engineering change occurs during the creation of new design solutions. The system then provides an estimate of the change in required resources and expected benefits through comparative analysis. Through these means, the proposed tool aims to help project managers identify an optimal design solution.The main goal of the proposed model is to increase product knowledge in the early stages of design to support project managers and design engineers in their decision making process. This is achieved through the visualization of the effects of engineering changes. In this thesis, the details of the proposed decision support system (DSS) are described and illustrated with a simple example of a thermoflask.De nombreux produits d'usage courant ont été conçus en modifiant des produits déjà existants. L'évolution constante des tendances du marché actuel et la demande croissante des clients pour des produits de qualité forcent les entreprises à effectuer des modifications fréquentes en vue de créer de nouveaux produits. Les défis associés à la modification de produit ont incité beaucoup d'entreprises à développer une stratégie de conception adaptative permettant de créer de nouveaux produits en améliorant de manière incrémentielle les produits existants. Ce mémoire propose un système d'aide à la décision visant à appuyer les gestionnaires en développement de produits dans l'analyse des mesures de performance d'un projet tels que l'effort et le temps de développement, le coût et le potentiel de revenu, la satisfaction de la clientèle, la marge de profit et le risque. Le modèle proposé est un calculateur spécialisé intégrant la maison de la qualité (HOQ), la technique d'analyse fonctionnelle de système (diagramme FAST), l'analyse du risque, l'analyse de la complexité du produit et l'analyse de la propagation de la modification. Il est ainsi possible de fournir une vue d'ensemble du processus de conception du produit allant des attributs du produit et du risque de la conception jusqu'aux coûts et aux efforts requis.L'analyse des diverses solutions de conception est effectuée en comparant les mesures de performance obtenues avec celles qui sont associées à la conception initiale. Le système permet de recalculer les mesures de performance lorsque des modifications techniques sont apportées dans le cadre de la création de nouvelles solutions de conception. Le système fournit alors, par le biais d'une analyse comparative, une estimation de l'impact de la modification sur les ressources requises et les avantages escomptés. À l'aide de ces fonctionnalités, l'outil proposé vise à aider les chefs de projet à trouver la solution de conception optimale.Le principal objectif du modèle proposé est d'augmenter la connaissance du produit dès les étapes préliminaires de la conception afin d'appuyer le processus de prise de décision des chefs de projet et des ingénieurs de conception. Cet objectif est réalisé par la visualisation des impacts d'une modification technique. Dans ce mémoire, le système d'aide à la décision (SAD) proposé est décrit de manière détaillée et illustré par un exemple simple, celui d'un contenant isotherme.

Biogas is the most emerging industrial sector for energy production from renewable sources at National and European levels, and growing government funds favor the development of its market. From a process safety standpoint, Seveso Directive (Directive 2012/18/EU of the European Parliament and of the Council), but Biogas plants are complicated enough to require both their specific technology and an accurate risk assessment for design purposes. The number of accidents involving biogas plants has been too many to be ignored. Biogas plants are often operated wrongly, deficient in technological details and incorrectly scaled-up. Moreover, all these mistakes are repeated over and over again. Therefore, there is the pressing need for an assessment of the reliability of these plants in order to operate them safely. For this reason, a quantitative risk assessment was carried out to on a biogas production plant.

In this study cost-benefits problems concerning the knapsack problem of limited resources is studied and how this relates to an attacker perspective when choosing defense strategies. This is accomplished by adopting a cost-benefit method and merging it with game theory. The cost-benefit method chosen for this study is the Analytical Hierarchy Process and from the field of game theory the Bayesian Nash Equilibrium is used. The Analytical Hierarchy Process allows the user to determine internally comparable weights between elements, and to bring in a security dimension to the Analytical Hierarchy Process a sub category consisting of confidentiality, integrity and availability is used. To determine the attacker strategy and, in effect, determine the best defense strategy the Bayesian Nash Equilibrium is used.

.Amgen is attempting to increase the impact that its products make in people's lives. To meet this goal, the company is aggressively working to reach more patients through growth opportunities in international markets and expects to significantly increase its existing footprint and product impact over the next several years. While the current market entry practices for emerging markets are meeting Amgen's needs, rapid expansion poses significant challenges. This thesis explores two primary aspects, the investigation of improvement opportunities in the commercialization of emerging markets and the development of a risk assessment model applicable to new market commercial entry. Both aspects relate to the larger problem of rapid international expansion and support its resolution in different forms. The assessment of improvement opportunities for emerging market commercialization strives to develop a tangible set of actions the organization can take forth in order to enhance the planning and execution of new market entry. The analysis is accomplished through an in depth study to determine the current level performance for commercial market entry. Based on the current state determination, a future vision is established which incorporates fundamental principles of operational excellence methodologies, integrating various techniques to develop a cohesive approach for improving current entry practices. An improvement roadmap is developed, detailing out specific actions, utilizing a phased implementation approach that allows for making incremental improvements. The risk assessment model establishes a tool the organization can utilize in order to properly identify risk associated with emerging market entry and enhance the decision making process that occurs at a senior leadership level as to whether or not a country should be entered. A scenario based evaluation methodology integrates cross-functional expertise across the organization assimilating information that is normally isolated to a small group within the company. The model determines risk levels for each scenario, generates a risk report and an output review is conducted with subject matter experts (SME) and functional leads. Scenarios that potentially require remediation are reviewed in a detailed risk assessment and resolved as necessary. Any substantial cost associated with control efforts are incorporated into the financial analysis for the target launch country, providing a better depiction of cost versus reward. Thus, the model increases the firm's ability to make agile risk-informed market entry decisions while providing a standardized method that is scalable cross-regionally.

There has been growing public concern regarding the threat to people and
environment from industrial activities, thus more rigorous regulations. The investigation
of almost all the major accidents shows that we could have avoided those tragedies with
effective risk analysis and safety management programs. High-quality risk analysis is
absolutely necessary for sustainable development.
As a powerful and systematic tool, fault tree analysis (FTA) has been adapted to
the particular need of chemical process quantitative risk analysis (CPQRA) and found
great applications. However, the application of FTA in the chemical process industry
(CPI) is limited. One major barrier is the manual synthesis of fault trees. It requires a
thorough understanding of the process and is vulnerable to individual subjectivity. The
quality of FTA can be highly subjective and variable.
The availability of a computer-based FTA methodology will greatly benefit the
CPI. The primary objective of this research is to develop a computer-aided fault tree
synthesis methodology for CPQRA. The central idea is to capture the cause-and-effect
logic around each item of equipment directly into mini fault trees. Special fault tree
models have been developed to manage special features. Fault trees created by this
method are expected to be concise. A prototype computer program is provided to
illustrate the methodology. Ideally, FTA can be standardized through a computer
package that reads information contained in process block diagrams and provides
automatic aids to assist engineers in generating and analyzing fault trees.
Another important issue with regard to QRA is the large uncertainty associated
with available failure rate data. In the CPI, the ranges of failure rates observed could be
quite wide. Traditional reliability studies using point values of failure rates may result in
misleading conclusions. This dissertation discusses the uncertainty with failure rate data
and proposes a procedure to deal with data uncertainty in determining safety integrity
level (SIL) for a safety instrumented system (SIS). Efforts must be carried out to obtain
more accurate values of those data that might actually impact the estimation of SIL. This
procedure guides process hazard analysts toward a more accurate SIL estimation and
avoids misleading results due to data uncertainty.

Implementeringen av trafikstyrningssystemet European Rail Traffic Management System (ERTMS), som för närvarande det största infrastrukturprojektet i Sverige, kommer successivt att ersätta det nuvarande systemet Automatic Train Control (ATC) fram till 2035. På grund av Sveriges nyligen slutförda avreglering av järnvägsmarknaden är de viktigaste aktörerna i implementationsprocessen de aktörer som ansvarar för tågen (tågoperatörerna) och den som ansvarar för infrastrukturen (Trafikverket). Arbetet är utfört på uppdrag av Trafikverket och syftar till att undersöka riskfördelningen mellan huvudintressenterna i samband med implementeringen av ERTM. En riskanalys med avseende på tekniska risker och finansiella risker är utförd samt en litteraturstudie och intervjuer med relevanta personer inom sektorn. Resultaten visar en motvilja från operatörerna att implementera tekniken och betydande skillnad i den risk som de två aktörerna är utsatta för. Operatörerna exponeras för en relativt hög risk i varje scenario som undersöks och som potentiellt kräver riskreducerande åtgärder. I ett scenario exponeras operatörerna för oacceptabelt hög finansiell risk som kräver riskreduceringsåtgärder. Transportverket är föremål för låg risk i alla scenarier som undersökts. Data från studien tyder på att motviljan från operatörerna mot implementeringen av ERTMS beror på att de risknivåer som denna grupp utsätts för inte lever upp till de fördelar de förväntar sig att systemet kommer leverera.Currently the largest infrastructure project in Sweden, the implementation of the rail traffic management system European Rail Traffic Management System (ERTMS) will gradually replace the incumbent system Automatic Train Control (ATC) until 2035. Due to Sweden’s recently completed deregulation of the railway market the main stakeholders in this implementation process are the actors responsible for operations (the train companies) and the actor responsible for the infrastructure (the Swedish Transportation Administration). The thesis is commissioned by the Swedish Transportation Administration and aims at examining the allocation of risk associated with the implementation of ERTMS among key stakeholders. A risk analysis with regards to technological risk and financial risk is conducted as well as a literature study and interviews with relevant persons in the sector. The results reveal a hesitation from operators to implement the technology and considerable difference in the risk the two main stakeholders are subject to. The operators maintain a relatively high level of risk in every scenario examined, potentially requiring risk reduction measures. In one scenario the operators are subject to inacceptable levels of financial risk that demands risk reduction measures. The Swedish Transportation Administration is subject to low levels of risk in all scenarios examined. Data from the study suggests that the hesitation from operators to implement the technology may be due to the levels of risk they are exposed to do not match the benefit they expect the system will provide.

Idag byggs infrastrukturen ut genom storskaliga projekt i en allt större utsträckning, vilket ökar intresset för planering, utförande och styrning. Sverige investerar i runda tal 100 miljarder kronor i byggande, drift och underhåll av infrastruktur varje år. För att effektivisera investeringarna är det viktigt att lösningar, samverkan och ledarskap går hand i hand. Stora infrastrukturprojekt innebär stora risker. Vid bygget av en väg ingår många anställda och arbetsområden med byggmaskiner, kranar och sprängämnen som kan påverka markförhållandena på plats. Därmed är identifiering, bedömning och prioritering av risker viktigt för att inte förlora greppet om säkerheten i projektet. Syftet med examensarbetet är att undersöka och beskriva riskhanteringen i ett pågående infrastrukturprojekt som utförs av NCC Infrastructure inom Förbifart Stockholm, Hjulsta Norra. Genom att samla data från litteratur och information på plats har problem och effektiviseringsmöjligheter sammanställts. Examensarbetet kan användas för att sprida förståelse för att risktänkande är en viktig del i strävan mot lönsamhet i ett projekt. Studien är utfört som ett examensarbete. Omfattningen är 30 högskolepoäng (motsvarar 20 veckors heltidsstudier) och begränsar därför omfattningen av studien i tid. De risker som valts ut från det pågående projektet Hjulsta Norra är ett begränsat antal som är prioriterade som de viktigaste. Som underlag till prioritering av risker i studien användes en litteraturundersökning samt intervjuer. Avgränsning av studien är produktionsskedet, vilket inriktar sig på de risker som uppkommer under byggprocessen i ett större infrastrukturprojekt. Det är hanterat ur entreprenörens perspektiv. De urval av intervjupersoner som har gjorts är en liten del av de som är inblandade i projektet och området. Därmed är det inte alltid möjligt att få med all information och erfarenhet som existerar. Utvald riskprocess och riskanalysmetod är förenklad och visar därför inte detaljerade faser som kan ha en extra verkan på resultatet. På grund av avgränsningar är det inte möjligt att identifiera och analysera alla risker i projektet. Studien visar att riskhantering är viktigt i stora infrastrukturprojekt. Det kan vara en avgörande faktor för hur lyckade inplanerade aktiviteter blir för slutresultatet. För att nå framgång behöver identifiering av miljömässiga, tekniska och organisatoriska risker göras. En annan viktig faktor är hur samarbetet mellan beställare och entreprenör fungerar i ett projekt och under produktionsskedet. En framtida utveckling av riskhanteringen i stora infrastrukturprojekt föreslås inriktas mot att skapa en bra organisation och samarbete mellan beställare och entreprenör i byggskedet. Riskhantering bör vara en naturlig del i projektstyrningen. Fortsatta studier bör därför inriktas mot att utveckla ett enkelt och produktionsanpassat system för riskhantering.A functioning transport infrastructure creates connections that are constantly moving, thus improving the economy. Today, infrastructure is being expanded through large-scale projects to an increasing extent, which increases the interest in planning, execution and management. Sweden invests around 100 billion SEK in construction, operation and maintenance of infrastructure each year. In order to make investments more efficient, it is important that solutions, collaboration and leadership go hand in hand. Large infrastructure projects involve major risks. When constructing a highway, many employees and work areas include construction machines, cranes and explosives that can affect soil conditions on site. Thus, identification, assessment and prioritization of risks are important in order not to lose the grip on the safety of the project. The purpose of the thesis work is to investigate and describe risk management in an ongoing infrastructure project conducted by NCC Infrastructure in Förbifart Stockholm, Hjulsta Norra. By collecting data from literature and on-site information, problems and efficiency opportunities have been compiled. The thesis work can be used to spread understanding that risk thinking is an important part of the pursuit of profitability in a project. The study is executed as a degree project. The scope is 30 credits (equivalent to 20 weeks full-time studies), thus limiting the scope of the study in time. The risks chosen from the ongoing project Hjulsta Norra are a limited number that are prioritized as the most important. As a basis for prioritizing risks in the study, a literature survey and interviews were used. Limitation of the study is the production phase, which focuses on the risks that arise during the construction process in a major infrastructure project. It is handled from the contractor's perspective. The selection of interviews that have been made is a small part of those involved in the project and the area. Thus, it is not always possible to include all the information and experience that exists. The selected risk process and risk analysis method are simplified and therefore do not show detailed phases that can have an additional effect on the result. Due to limitations, it is not possible to identify and analyze all risks in the project. The study shows that risk management is important in major infrastructure projects. This can be a determining factor in how successful planned activities will be for the end result. To achieve success, identification of environmental, technical and organizational risks needs to be done. Another key factor is how cooperation between the client and the contractor works in a project and during the production phase. A future development of risk management in major infrastructure projects is proposed to focus on creating a good organization and collaboration between clients and contractors in the construction phase. Risk management should be a natural part of project management. Continued studies should therefore focus on developing a simple and production-adapted risk management system.

The purpose of this study was to examine the reflective essays of first-year, first-generation college students for evidence of self-directed learning at the conclusion of their first semester at the university. A phenomenological qualitative method was employed and a content analysis rating rubric used to identify and code evidence related to four themes: Self Awareness, Decoding and Pattern Fit, Autonomy/Responsibility, and Academic Success.
The study findings indicated that first-year, first-generation college students have the capacity to take ownership of their learning in ways exemplified by self-directed learners. Participants demonstrated deep reflection and metacognition and their essays revealed unexpected student vulnerability as they voiced fears and hopes with a nearly innocent transparency and candor. Study findings also emphasized the importance of a support system that includes coursework designed to facilitate understanding of individual learner characteristics, emphasize strategies to maximize learner efforts that lead to successful outcomes, and empower students to become more self-directed. This study also expands the field of adult education by providing evidence that learner control is a key component of self-direction and is positively correlated to academic success. Ample evidence related to metacognition, self-regulation, and learner control was identified in the essay data.

Der volle Inhalt der QuelleAnnotation:
Recently the eld of actuarial mathematics has experienced a large development due to a signi cant increase of demands for insurance and nancial risk quanti cation due to the fact that the implementation of a complex of rules of international reporting standards (IFRS) and solvency reporting (Solvency II) has started. It appears that the key question for solvency measuring is determination of probability distribution of future cash ows of an insurance company. Solvency is then reported through an appropriate risk measure based e.g. on a percentile of this distribution. While as present popular models are based solely on aggregated data (such as total loss development from a certain time period), the main objective of this work is to scrutinize possibilities of modelling of the reserve risk (i.e. roughly said, the distribution of the ultimate incurred value of claims that have already happened in the past) based directly on individual claims. These models have not yet become popular and to the author's knowledge an overview of such models has not been published previously. The assumptions and speci cation of the already published models were compared to the practical experience and some inadequacies were pointed out. Further more a new reserve risk model was constructed which is believed to have practically more suitable assumptions and properties than the existing models. Theoretical aspects of the new model were studied and distribution of the ultimate incurred value (the modelled variable) was derived. An emphasis was put also on practical aspects of the developed model and its applicability in the case of industrial use. Therefore some restrictive assumptions which might be considered realistic in variety of practical cases and which lead to a signi cant simpli cation of the model were identi ed throughout the work. Furthermore, algorithms to reduce the number of the necessary calculations were developed. In the last chapters of the work, an e ort was devoted to the methods of the estimation of the considered parameters respecting practical limitations (such as missing observations at the time of modelling). For this purpose, survival analysis was (amongst other methods) applied.

Der volle Inhalt der QuelleAnnotation:
Motivated by the paucity of high quality stillbirth surveillance data and the spatial analyses of such data, the current research sets out to quantitatively describe the pattern of stillbirth events that may lead to mechanistic hypotheses. We broaden the appeal of Bayesian Poisson point process modeling to quantify excess risk while accounting for unobserved heterogeneity. We consider a practical data analysis strategy when fitting the point process model and study the utility of parameterizing the intensity function governing the point process to include a maternal contextual effect to account for variation due to multiple stillbirth events experienced by the same mother in independent pregnancies. Simulation studies suggest that our practical data analysis strategy is reasonable and that there is a variance-bias trade-off associated with the use of a maternal contextual effect. The methodology is applied to the spatial distribution of stillbirth events in Iowa during the years 2005 through 2011 obtained using an active, statewide public health surveillance approach. Several localized areas of excess risk were identified and mapped based on model components that captured the nuanced and salient features of the data. A conditional formulation of the point process model is then considered, which has two main advantages: the ability to easily incorporate covariate information attached to both stillbirth and live birth, as well as obviate the need to estimate the background intensity. We assess the utility of the conditional approach in the presence of unobserved heterogeneity, compare two Bayesian estimation techniques, and extend the conditional formulation to adequately capture spatio-temporal effects. The motivating study comes from the Iowa Registry for Congenital and Inherited Disorders who has a committed interest in the surveillance and epidemiology of stillbirth in Iowa and whether the occurrence might be geographically linked.

Fire plays an important role in forest ecosystem management depending on the dual character of it. It should be managed and supervised effectively. In this particular study, the study area was located in the north part of Gävleborg County in Sweden, which is in a high- latitude region. Seven factors, divided into natural factors and human caused factors, were extracted from digital elevation model (DEM), classified land use map and feature shape files provided by National Land Survey of Sweden (Lantmäteriet). Two different weighting schemes for the factors were determined by the Analytic Hierarchy Process (AHP) method. With the help of ArcGIS 9.3 and Erdas 9.3, two classified result maps were obtained, where forest fire risk ranks were shown as five classes, very low, low, moderate, high and very high. The 43 fire incidents in the year 2007 and 2008 recorded by Global Fire Management System were used to evaluate the results. The results show that the higher rank the region is, the larger is the probability for forest fire risk and higher the risk to spread the fire. Furthermore, according to the occurrence time of the fire incidents, the period of time from end of May to beginning of June was generalized as a dangerous period for forest fire risk in this study area. After analyzing and discussing, even if there might be some uncertainties caused by variable selection, resolution problem and weighting schemes, the results were generally reliable.

Their physical properties and also their characteristics, such as measure qualification, lot sampling and dispatching strategy and risk levels, are considered. Also, a new procedure is developed that helps to determine which sampling strategy fits better according to the metrology workshop characteristics and risk values.New approaches are then proposed to optimize the sampling rates for different types of metrology tools respecting the metrology capacity and taking into account parameters such as throughput rates of process machines and metrology tools, and the failure probabilities of process machines. The numerical experiments show that the metrology capacity is better used and process machines are efficiently controlled, depending on their characteristics, paying more attention the critical machines.In the final part of the thesis, simulation models of several metrology workshops are developed. These models reproduce the behaviour of the workshops to better understand them and to evaluate the impact of proposed improvements

Background: South Korea is one of the countries currently enforcing more strict emission standards for heavy-duty vehicles, as a result of the global push to restrict pollution. In addition, there has been recent scandals involving several well-established automotive companies manipulating emissions tests and not fulfilling regulations. This has resulted in the government increasing the pressure for companies to apply the correct certifications even further. For companies to sell vehicles on the South Korean market, the vehicles must be certified and approved by the government, known as homologation. This process partly involves self-certification, meaning that companies are responsible for applying the correct certification themselves. It is therefore of great importance to have structured and clear processes to mitigate risks of error-making, in order to avoid financial and legal repercussions. Purpose: The study aims to identify and analyze the risks in error-making. Therefore, the purpose is to understand and propose improvement actions to the current homologation processes at Scania Korea Group. Method: The thesis utilized a case study strategy with a descriptive approach to illustrate the process. An exploratory approach was used in combination to identify risks and provide improvement actions. Qualitative data in conjunction with theory around business process improvement were utilized to fulfill the purpose. Firstly, interviews and focus groups were conducted to map the process. Thereafter, a failure mode and effect criticality analysis(FMECA) was used to analyze the process. Lastly, improvement actions were decided based on best practices and benchmarking. Findings and recommendations: The homologation process contain many high severity risks such as certifying the incorrect truck specifications or not complying with regulations, due to not updating the certifications when product changes occur. Furthermore, government approvals incorporate a substantial part of the process lead-time. As such, it is concluded that quality is of utmost importance, both to decrease lead-time and minimize risks with detrimental consequences. The analysis showed evidence of lacking controls/gates in the process, which enables errors and incorrect applications to move through. Improvements regarding increased project structure, planning and communication within SKG were suggested. Further improvement points were an increased number of controls and more clear delegation of responsibility. Recommendations for future studies: We propose to further investigate the root-causes of the inherent risks in the process. Future studies should also look to gather additional data from other heavy-duty automotive companies in South Korea, since it could provide deeper and more generalizable results. Lastly, we recommend future research to utilize a quantitative research approach, providing more statistical evidence.

The objective of the research was to develop and validate a multifaceted model such as a fuzzy Analytical Hierarchy Process (AHP) model that considers both qualitative and quantitative elements with relative significance in assessing the likelihood of falls and aid in the design of NASA Ground Support Operations in aerospace environments. The model represented linguistic variables that quantified significant risk factor levels. Multiple risk factors that contribute to falls in NASA Ground Support Operations are task related, human/personal, environmental, and organizational. Six subject matter experts were asked to participate in a voting system involving a survey where they judge risk factors using the fundamental pairwise comparison scale. The results were analyzed and synthesize using Expert Choice Software, which produced the relative weights for the risk factors. The following are relative weights for these risk factors: Task Related (0.314), Human/Personal (0.307), Environmental (0.248), and Organizational (0.130). The overall inconsistency ratio for all risk factors was 0.07, which indicates the model results were acceptable. The results show that task related risk factors are the highest cause for falls and the organizational risk are the lowest cause for falls in NASA Ground Support Operations. The multiple risk factors weights were validated by having two teams of subject matter experts create priority vectors separately and confirm the weights are valid. The fuzzy AHP model usability was utilizing fifteen subjects in a repeated measures analysis. The subjects were asked to evaluate three scenarios in NASA KSC Ground Support Operations regarding various case studies and historical data. The three scenarios were Shuttle Landing Facility (SLF), Launch Complex Payloads (LCP), and Vehicle Assembly Building (VAB). The Kendall Coefficient of Concordance for assessment agreement between and within the subjects was 1.00. Therefore, the appraisers are applying essentially the same standard when evaluating the scenarios. In addition, a NASA subject matter expert was requested to evaluate the three scenarios also. The predicted value was compared to accepted value. The results from the subject matter expert for the model usability confirmed that the predicted value and accepted value for the likelihood rating were similar. The percentage error for the three scenarios was 0%, 33%, 0% respectively. Multiple descriptive statistics for a 95% confidence interval and t-test are the following: coefficient of variation (21.36), variance (0.251), mean (2.34), and standard deviation (0.501). Model validation was the guarantee of agreement with the NASA standard. Model validation process was partitioned into three components: reliability, objectivity, and consistency. The model was validated by comparing the fuzzy AHP model to NASA accepted model. The results indicate there was minimal variability with fuzzy AHP modeling. As a result, the fuzzy AHP model is confirmed valid. Future research includes developing fall protection guidelines.Ph.D.

Statistical process monitoring and hierarchical Bayesian modeling are two ways to learn more about processes of interest. In this work, we consider two main components: risk-adjusted monitoring and Bayesian hierarchical models for spatial data. Usually, if prior information about a process is known, it is important to incorporate this into the monitoring scheme. For example, when monitoring 30-day mortality rates after surgery, the pre-operative risk of patients based on health characteristics is often an indicator of how likely the surgery is to succeed. In these cases, risk-adjusted monitoring techniques are used. In this work, the practical limitations of the traditional implementation of risk-adjusted monitoring methods are discussed and an improved implementation is proposed. A method to perform spatial risk-adjustment based on exact locations of concurrent observations to account for spatial dependence is also described. Furthermore, the development of objective priors for fully Bayesian hierarchical models for areal data is explored for Gaussian responses. Collectively, these statistical methods serve as analytic tools to better monitor and model spatial processes.Ph. D.

A turn to more sustainable resources has lead the research during the last decades to algae. Algae is a resource that has been utilized for thousands of years offering a variety of possibilities. Nevertheless modern technology were able to uncover algae’s great potential and pave the way for alternative uses such as biofuel and biomaterial production. Towards that direction, ‘Seafarm’ aims in utilizing algae in the most efficient and sustainable way. For that purpose various steps have been established, including the biorefinery step which entail among other the extraction of carbohydrates from brown algae. The current thesis is based on an extraction of carbohydrates from Saccharina latissima, a brown algae species, which was developed by Viktor Öberg during his master thesis at KTH. The aim of this work is to assist in the scaling up of that laboratory process by analyzing the basic steps and substances of the process, investigating its environmental performance and identifying improvement areas for theoretical optimization. The results of the aforementioned analysis include a substance flow analysis which reveals the basic steps of the process and constitute the basis for further analysis. The second step examines the environmental performance of the process based on the chemical selection. Hence the results are a risk assessment of chemicals with performance indicators for each chemical as well as the whole process. The final part provides a theoretical optimization of the process based on literature studies where the recommendations are divided in production optimization and environmental performance. The above results constitute the basis of the analysis of the process and sets the foundations for scaling up the process at an industrial level. The current analysis in combination with an energy and economic assessment could be used for the designing of the process and its integration in the biorefinery.

Der volle Inhalt der QuelleAnnotation:
This thesis sets out to provide a systematic study of stakeholder partnership building of BP in Colombia and Hoechst in Germany in the context of social risk management. Each company built an NGO and a community partnership that became an integral part of firms' strategy. In examining and evaluating the two companies and the four stakeholder partnerships, the leading research question of how firms build stakeholder partnerships is answered. The present study seeks to identify the characteristics of stakeholder partnership building, as well as to isolate the similarities and differences of this process. Additionally, it is an attempt to define the features of the firms' social risk navigation as context of this research project. The thesis is divided into four parts. The first part introduces the research phenomenon, reviews conceptual foundations, and elaborates methodological issues. The case studies of BP and Hoechst are subdivided into internal processes of social integration and reintegration with regard to the two companies, and external processes of partnership building with regard to the four stakeholder partnerships that are chronologically presented in part two. Part three conceptualises stakeholder partnership building in terms of navigating social risk and partnership alchemy. Finally, part four comprises the research synopsis and reflection. Business and society, stakeholder theory, and strategic relationships are the theoretical areas that contributed to the framework for analysing partnership building. Two longitudinal in-depth case studies provide qualitative data for the processual analysis. The empirical data are categorised, aggregated and compared, in order to extract research findings. The contribution of this research is the extension of behavioural stakeholder theory. It develops is a stakeholder partnership building theory that comprises three parts. First, the 4-Ps of stakeholder partnership building are identified. Second, variables are isolated that describe these elements of partnership alchemy. Finally, four patterns of stakeholder partnership building are identified. As a result, the research presents four propositions for partnership building. Based on the analysis of firms' navigation of social risk, a fifth proposition distinguishes between firm-specific and partnership-specific partnership building. The empirical data provides a contribution to knowledge in its own right by providing detailed insight into the practice of social risk management through stakeholder partnership building.

Der volle Inhalt der QuelleAnnotation:
The intent of this dissertation is to generate a set of non-dominated finite-memory policies from which one of two agents (the leader) can select a most preferred policy to control a dynamic system that is also affected by the control decisions of the other agent (the follower). The problem is described by an infinite horizon total discounted reward, partially observed Markov game (POMG). Each agent’s policy assumes that the agent knows its current and recent state values, its recent actions, and the current and recent possibly inaccurate observations of the other agent’s state. For each candidate finite-memory leader policy, we assume the follower, fully aware of the leader policy, determines a policy that optimizes the follower’s criterion. The leader-follower assumption allows the POMG to be transformed into a specially structured, partially observed Markov decision process that we use to determine the follower’s best response policy for a given leader policy. We then present a value determination procedure to evaluate the performance of the leader for a given leader policy, based on which non-dominated set of leader polices can be selected by existing heuristic approaches.
We then analyze how the value of the leader’s criterion changes due to changes in the leader’s quality of observation of the follower. We give conditions that insure improved observation quality will improve the leader’s value function, assuming that changes in the observation quality do not cause the follower to change its policy. We show that discontinuities in the value of the leader’ criterion, as a function of observation quality, can occur when the change of observation quality is significant enough for the follower to change its policy. We present conditions that determine when a discontinuity may occur and conditions that guarantee a discontinuity will not degrade the leader’s performance. This framework has been used to develop a dynamic risk analysis approach for U.S. food supply chains and to compare and create supply chain designs and sequential control strategies for risk mitigation.

Bakgrund: Människor drabbade av naturrelaterade katastrofer fortsätter att stiga i antal tillsammans med de kostnader som följer i katastrofernas spår. Skadorna fördelas ojämnt mellan länder och samhällsgrupper och utgör både ett humanitärt problem och en fråga om ojämlikhet. Att reducera risker är därmed en förutsättning för att uppnå hållbar utveckling. Sendai-ramverket för katastrofriskreducering 2015-2030 talar om vikten av att riskhantering baseras på en förståelse av risker. Risk- och sårbarhetsanalys (RSA) är ett verktyg för att skapa förståelse av risker och åtgärder att vidta för att reducera dessa. Stöd till att utveckla processer för analys av risker och sårbarheter har identifierats som komparativa fördelar för svenskt bistånd inom de internationella kapacitetsutvecklingsinsatser som Myndigheten för samhällsskydd och beredskap (MSB) bedriver. Trots förekomsten av erfarenheter, lagstöd och vägledningar saknas i större omfattning studier av hur arbetet genomförs och utnyttjas. Forskning om olycksinsatsplanering pekar ut själva processen som viktigare än de planer som produceras. Detta sammantaget visar på ett behov att identifiera viktiga erfarenheter från den svenska RSA-processen, erfarenheter som kan informera MSBs kapacitetsutvecklingsinsatser inom RSA. Syfte: Syftet med studien är att identifiera vad deltagare uppfattar som goda erfarenheter av det RSA-arbete som bedrivs av svenska kommuner med fokus på själva processen Metod: Studien som är av kvalitativ karaktär genomförs med en abduktiv ansats där deltagare intervjuas, inspelningar transkriberas och innehållet analyseras med kvalitativ innehållsanalys. Som teoretiska utgångspunkter att jämföra studiens empiri används Risk Governance, Social Learning och en tillämpning av Design Science. Resultatet: Studiens resultat presenteras i form av tema, kategorier och underkategorier. På latent nivå härleds temat; lära tillsammans till nytta för ett säkrare samhälle, vilket fångar fundamentala tankegångar om att analysarbetet handlar om att lära sig mer, att det behöver göras tillsammans och att resultatet behöver komma till nytta, allt i en strävan mot ett säkrare samhälle. Det manifesta innehållet presenteras i kategorierna; funktionellt lagarbete, lärande och förändring samt främjande strategier och arrangemang. Kategorierna består i sin tur upp av tio underkategorier. Slutsatser: Bland viktiga slutsatser från arbetet med RSA är betydelsen av att forma team av deltagare med varierade roller, kompetens och perspektiv. Vidare att skapa forum och miljöer som främjar tillit och ömsesidigt utbyte. Här är samordnarens roll av avgörande betydelse. Ytterligare en slutsats är att ta vara på drivkrafter om nytta och användbarhet för ett flexibelt genomförande. Behovet av förankring, ägarskap och att bygga på vad som redan finns är andra betydelsefulla slutsatser. Vid stöd till nationell utveckling av RSA behöver lagstiftnings stimulerande men också hämmande effekter beaktas. Hur myndigheters stöd utformas behöver baseras på hur behoven ser ut hos de som ska genomföra RSA.

A implementação de programas de qualidade na linha de produção tem sido utilizada por empresas para garantir a competitividade em um mercado cada dia mais competitivo. A busca por equilíbrio entre qualidade e custos é uma constante na área industrial e, neste contexto, melhorias no processo produtivo são fundamentais. No setor florestal, responsável por 3,5% do PIB do país em 2007, a gestão da qualidade aplicada à linha de produção é recente e muitos aspectos importantes não são considerados. O objetivo deste trabalho foi identificar e avaliar os pontos críticos do processo de produção de uma empresa de processamento da madeira. Para tanto, a pesquisa foi dividida em três etapas. A primeira foi o mapeamento do processo da empresa e a elaboração de fluxogramas para as atividades. A segunda fase foi a identificação e avaliação dos pontos críticos por entrevistas com funcionários, utilizando metodologia FMEA (Failure Mode and Effect Analysis) e diagramas de Ishikawa, que relaciona as falhas com suas possíveis causas. A terceira fase foi a avaliação do processo produtivo, empregando o controle estatístico do processo nos principais pontos críticos e a determinação da capacidade do processo pelo índice Cpk. Os resultados mostraram a existência de 6 sub-processos, sendo dois críticos. Nesses setores foram identificados 15 pontos críticos, com cinco deles selecionados para serem avaliados. Os gráficos de controle para variáveis indicaram que o processo produtivo da empresa é instável quanto ao item peças fora de dimensão em ambos setores, enquanto o índice Cpk permitiu concluir que a empresa não é capaz de produzir pisos de madeira dentro das especificações. Para os atributos, o processo era estável, exceto para peças marcadas pela lixa. A causa de não conformidades mais significativa foi a aferição dos equipamentos de medição, que resultou em processos com baixa variação, porém com médias distantes das especificações.The implementation of quality programs in line production has been used by companies to guarantee the competitiveness in a market more competitive every day. The search for balance between quality and costs is a constant in industrial area and, in this context, improvements in the productive process are fundamentals. In the forest sector, responsible for 3,5% of the countrys GDP in 2007, the quality management applied to the line production is recent and many important aspects are not considered. This study aimed to identify and evaluate the critical points of the process of production of a company of wood processing. Therefore, the research was divided in three stages. The first one was the process mapping of the company and the elaboration of flowcharts for the activities. The second phase was identify and evaluate the critical points for interviews with employees, using FMEA (Failure Mode and Effect Analysis) methodology and Ishikawas diagram, which relates the failure with their possible causes. The third phase was the evaluation of the productive process, applying statistical process control in the main critical points and the determination of the process capability for the Cpk index. The results showed the existence of 6 processes, two of them critical. In those sectors 15 critical points were indentified and 5 were selected for evaluation. The control charts for variables indicated that the process is unstable for the item pieces out of dimension in both processes, while the Cpk index allowed to conclude that the company is not capable to produce wood flooring according to the specifications. For the attributes, the process was stable, except for pieces marked by the sandpaper. The more significant cause of non-conformities was the gauging of the measurement equipments, that resulted in processes with low variation, however with means far from the specifications.

This thesis studies the generalization ability of machine learning algorithms in a statistical setting. It focuses on the data-dependent analysis of the generalization performance of learning algorithms in order to make full use of the potential of the actual training sample from which these algorithms learn.¶
First, we propose an extension of the standard framework for the derivation of
generalization bounds for algorithms taking their hypotheses from random classes of functions. This approach is motivated by the fact that the function produced by a learning algorithm based on a random sample of data depends on this sample and is therefore a random function. Such an approach avoids the detour of the worst-case uniform bounds as done in the standard approach. We show that the mechanism which allows one to obtain generalization bounds for random classes in our framework is based on a “small complexity” of certain random coordinate
projections. We demonstrate how this notion of complexity relates to learnability
and how one can explore geometric properties of these projections in order to derive estimates of rates of convergence and good confidence interval estimates for the expected risk. We then demonstrate the generality of our new approach by presenting a range of examples, among them the algorithm-dependent compression schemes and the data-dependent luckiness
frameworks, which fall into our random subclass framework.¶
Second, we study in more detail generalization bounds for a specific algorithm which is of central importance in learning theory, namely the Empirical Risk Minimization algorithm (ERM). Recent results show that one can significantly improve the high-probability estimates for the convergence rates for empirical minimizers by a direct analysis of the ERM algorithm.
These results are based on a new localized notion of complexity of subsets of hypothesis functions with identical expected errors and are therefore dependent on the underlying unknown distribution. We investigate the extent to which one can estimate these high-probability convergence rates in a data-dependent manner. We provide an algorithm which computes a data-dependent upper bound for the expected error of empirical minimizers in terms of the “complexity” of data-dependent local subsets. These subsets are sets of functions of empirical errors of a given range and can be
determined based solely on empirical data.
We then show that recent direct estimates, which are essentially sharp estimates on the high-probability convergence rate for the ERM algorithm, can not be recovered universally from empirical data.

Recent issuances of sukuk were confronted with wide criticism from, both by Islamic scholars and investors. The part of the problems arise due to the agency relations in sukuk structures that have a distinctive nature with great complexity and various features. Due to the higher complexity of the responsibilities undertaken by the agent, greater exposure to agency costs results. This research aims to examine sukuk associated risks, agency costs and Sharia issues. Specifically, it analyses asset-backed sukuk structures from financial and Sharia viewpoints. This is achieved by adopting a case study strategy and inductive approach to examine the legal and financial issues arising in three different types of asset linked sukuk structures. The data is collected using content analyses of sukuk prospectuses, AAOIFI Sharia standards and publications issued by international agencies with the aim of enabling the study to achieve insights into the market. Furthermore, information is gathered from Sharia scholars using semi structured interviews to generate some specific information on the issues involved. The objectives of this study are to analyse three key issues: based on theoretical discussions identify the risks arising in securities in general and sukuk in particular; to carry out a comparative analysis of the principle/agent conflicts which arise in different cases of sukuk investment; and to determine the extent of adherence to Sharia rules. The dissertation discusses in depth the agency costs that arise in asset-backed sukuk structures. It determines how these costs are minimized and conflicts managed in the applications. Among the strategies and tools used to reduce agency costs is to apply the concept of co-ownership. Under this type of agreement between the originator and investors, the sukuk structure becomes more competitive and shows a better allocation of the risks. Although the issuance of sukuk are reviewed and approved by eminent scholars, they show different levels of contradictions with AAOIFI Sharia standards. The study identifies the status of different stipulations of different contracts in terms of Sharia requirements. The research then shows the extent to which the compatibility of the sukuk cases differ with key Sharia principles. The analysis found that the key requirements are mostly related to the guarantee, ownership, principle, return and maintenance costs. It found out that SEC sukuk are far away from the spirit of Sharia as most of the essential requirements are not fulfilled. Sadara sukuk show better harmonious with AAOIFI requirements because of their unprecedented feature involved in their structure, which highlighted some of the distinctive nature of sukuk. Zamzam sukuk achieved the best harmonious with Sharia among the three applications. This positive result is attributed to the real ownership to the investment, meaning that there is no guarantee for the principle or the return. The results show that there is a higher exposure to risks related to liquidity legality in sukuk cases than in conventional bonds. More importantly is that the credit risk in sukuk cases are higher than in bond investments. The three cases were more exposed to the credit risks since any loss in the assets has to influence both the distribution amounts and the purchase undertaking. The critical point found is that despite SEC and Sadara sukuk cases involve higher exposure to credit risk as required in Islamic finance, they do not provide in turn a recourse to the assets according to the concept of sukuk. The cases also show that the purchase undertaking solves the agency conflicts, caused by the originator being the servicer. The undertaking device has reduced the incentive asymmetries from different perspectives.

Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. The vulnerability of a system is described as a sensitivity to threats and hazards, and is measured by P (Q(t) > q), i.e. the probability of at least one disturbance with negative societal consequences Q larger than some critical value q, during a given period of time (0,t]. The aim of the thesis is to present methods for quantitative vulnerability analysis of electric power delivery networks to enable effective strategies for prevention, mitigation, response, and recovery to be developed. Paper I provides a framework for vulnerability assessment of infrastructure systems. The paper discusses concepts and perspectives for developing a methodology for vulnerability analysis, and gives examples related to power systems. Paper II analyzes the vulnerability of power delivery systems by means of statistical analysis of Swedish disturbance data. It is demonstrated that the size of large disturbances follows a power law, and that the occurrence of disturbances can be modeled as a Poisson process. Paper III models electric power delivery systems as graphs. Statistical measures for characterizing the structure of two empirical transmission systems are calculated, and a structural vulnerability analysis is performed, i.e. a study of the connectivity of the graph when vertices and edges are disabled. Paper IV discusses the origin of power laws in complex systems in terms of their structure and the dynamics of disturbance propagation. A branching process is used to model the structure of a power distribution system, and it is shown that the disturbance size in this analytical network model follows a power law. Paper V shows how the interaction between an antagonist and the defender of a power system can be modeled as a game. A numerical example is presented, and it is studied if there exists a dominant defense strategy, and if there is an optimal allocation of resources between protection of components, and recovery.QC 20100831

Detta är en rapport som syftar till att kartlägga kvalificerade leverantörer till Aqua‐Nova AB. Företagets organisation är liten och består av fem anställda. Det är därför en utmaning att sälja nya projekt, övervaka tillverkning och vårda kundrelationer och samtidigt bedriva utvecklingsprojekt. Arbetet är baserat på tekniska rapporter som erhållits av Aqua‐Nova. Rapporterna utreder en möjlig optimering av destillationsprocessen med ejektorteknik. Målet med rapporten var att kartlägga kvalificerade leverantörer av ejektorer till Aqua‐Nova. Det ingående målet med rapporten var att besvara de fyra detaljerade målen som formulerades. Vilka fördelar respektive nackdelar skapas av att införa en ejektor i systemet? Vilka kundfördelar ger en ejektor? Vilka krav ställs på tekniken för att fungera tillsammans med Aqua‐Novas nuvarande system? Vilka krav ställs på leverantörerna vad gäller kompetens, leveransförmåga och pris? Genom Googlesökningar, undersökning av Achema industrimässa samt genom intervju hittades elva leverantörer som uppfyllde kravspecifikationen. Med Pugh‐ och Kesselring‐matriser utfördes en sållningsprocess i två steg. Det brittiska företaget Transvac Systems Ltd. fick högst poäng i båda sållningarna och anses således var den mest kvalificerade leverantören. Sållningsprocessen kompletterades med en konkurrentanalys, en riskanalys samt intervju för att besvara de detaljerade målen. Konkurrentanalysen utreder för‐ och nackdelar med utvecklingsprojektet och visar att Aqua‐Nova kan öka sina marknadsandelar genom differentiering av produkten. Fokus bör läggas på de marknader där kylvatten är en bristvara och de företag som lider av platsbrist. Kundfördelarna blir en mer miljövänlig och lönsam produkt. Riskanalysen svarar på om det föreligger en risk att implementera ny teknik i Aqua‐Novas system. Baserat på resultatet är risken, att ejektortekniken ska orsaka driftstörningar, minimal. Intervjun visar att en leverantör måste kunna leverera skräddarsydda ejektorer samt hur ejektorn bör utformas för att fungera i Aqua‐Novas system. Det slutgiltiga resultatet anses trovärdigt eftersom sållningsprocessen utfördes i två steg. Risk‐ och konkurrentanalysen ger en bild över de utmaningar företaget kan möta i och med utvecklingsprojektet. Arbetet bör kompletteras med en kostnadsanalys samt att en testanläggning utvecklas för att garantera lönsamhet och en funktionsduglig produkt.This is a report that aims to map qualified suppliers to Aqua‐Nova. The company's organization is small and consists of five employees. It is therefore a challenge to sell new projects, monitor production and care for customer relations and at the same time conduct development projects. The work is based on a technical report obtained by Aqua‐Nova. The report investigates a possible optimization of the distillation process using ejector technology. The purpose of this thesis was to investigate the most suitable subcontractor of ejectors for Aqua‐Nova. The purpose was to also answer the four detailed objectives. What advantages and disadvantages are created by introducing an ejector into the system? What customer benefits does an ejector provide? What requirements are placed on the technology to work together with Aqua‐Nova's current system? What requirements are placed on suppliers in terms of competence, delivery ability and price? Through Google searches, examination of Achema industrial fair and through interviews, eleven suppliers were found who met the requirements specification. With Pugh and Kesselring matrices, a two‐step screening process was performed. The British company Transvac Systems Ltd. got the highest score in both screenings and is thus considered the most suitable supplier. The screening process was supplemented by a competition analysis, a risk analysis and an interview to answer the detailed objectives. The competition analysis aims to investigate the pros and cons of the development project and shows that Aqua‐Nova can increase its market share by differentiating the product. The focus should be on the markets where cooling water is a scarce commodity and the companies that suffer from space shortages. The customer benefits become a more environmentally friendly and profitable product. The risk analysis shows whether there is a risk of implementing new technology in Aqua‐Nova's system. Based on the result, the risk of the ejector causing a downtime is minimal. The interview shows that a supplier must be able to deliver tailor‐made ejectors and how the ejector should be designed to work in the Aqua‐Nova system. The result can be considered credible since the screening process was performed in two steps. The risk and competition analysis give a representation of the challenges the company can face with the development project. The result ought to be supplemented by a cost analysis and developing of a test facility to ensure profitability and a functional product.
