Dissertação para obtenção do Grau de Mestre em Engenharia Electrotécnica e de ComputadoresThe main objective of this dissertation is to perform a Comparative Analysis of different Multicriteria Decision Making Methods applied to real-world problems, in order to produce relevant information to enable the incorporation of those methods on computational platforms. The current document presents a simple case study concerning a decision support application targeted for a real problem regarding retrofitting alternatives of a building with energy efficiency impact. The application process was started with the selection of two Multicriteria Decision Making Methods guided by a preexisting framework, and resulted in the choice of AHP and PROMETHEE II methodologies. These two methods were then combined with three different decision maker profiles (Conservative, Moderate and Aggressive) created by means of risk assessment profiling techniques for portfolio allocation. Afterwards, the chosen decision criteria were disposed in a Risk Pyramid according to their inherent level of risk regarding project evaluation. A match was then performed between the decision maker profiles and each criterion, so as to define a proper set of weights for the decision criteria and preference functions, with corresponding preference and indifference thresholds. Finally, three different sets of results (one for each decision maker profile) were produced using appropriate software, and a Sensitivity Analysis was performed over the criteria to understand their influence on the solution. The general conclusion of this Comparative Analysis is that the increase in the preference modelling ability of the methods brings up the least expected alternatives as recommendations for the decision maker. Besides, we have concluded that the decision profiles that allocate bigger weights to the riskiest criteria are the ones that produce the more dispersed set of results within each method application and within each decision maker profile.

Includes bibliography.The aim of this study was the design and implementation of an interactive decision support system, assisting a single decision maker in reaching a satisfactory decision when faced by a multicriteria decision making problem. There are clearly two components involved in designing such a system, namely the concept of decision support systems (DSS) and the area of multicriteria decision making (MCDM). The multicriteria decision making environment as well as the definitions of the multicriteria decision making concepts used, are discussed in chapter 1. Chapter 2 gives a brief historical review on MCDM, highlighting the origins of some of the more well-known methods for solving MCDM problems. A detailed discussion of interactive decision making is also given. Chapter 3 is concerned with the DSS concept, including a historical review thereof, a framework for the design of a DSS, various development approaches as well as the components constituting a decision support system. In chapter 4, the possibility of integrating the two concepts, MCDM and DSS, are discussed. A detailed discussion of various methodologies for solving MCDM problems is given in chapter 5. Specific attention is given to identifying the methodologies to be implemented in the DSS. Chapter 6 can be seen as a theoretical description of the system developed, while Chapter 7 is concerned with the evaluation procedures used for testing the system. A final summary and concluding remarks are given in Chapter 8.

Bibliography: leaves 142-149.The nature of human decision making dictates that a decision must often be considered under conditions of uncertainty. Decisions may be influenced by uncertain future events, doubts regarding the precision of inputs, doubts as to what the decision maker considers important, and many other forms of uncertainty. The multicriteria decision models that are designed to facilitate and aid decision making must therefore consider these uncertainties if they are to be effective. In this thesis, we consider the treatment of uncertainty in multicriteria decision making (MCDM), with a specific view to investigating the types of uncertainty that are most relevant to MCDM, [and] how the uncertainties identified as relevant may be treated by various different MCDM methodologies.

Bibliography: leaves 131-136.This dissertation investigates the application of Multicriteria Decision Making (MCDM) methodologies to the area of scenario based policy planning. We examine how the tools of MCDM can be used to develop a Decision Support System (DSS) that would allow management or policy planners to resolve conflicting goals and interests. Ideally, the resolution would be obtained by the various decision makers (DMs) in such a manner, that it satisfies all the relevant interest groupings at a maximum level of achievement for all concerned. This is not always possible and compromises need to be made that are fair and equitable to all the relevant interests. Stewart et al. (1993), in a report entitled: "Scenario Based Multicriteria Policy Planning for Water Management in South Africa", develop the principles of a procedure for implementing scenario based multicriteria policy planning. Their iterative procedure is illustrated in figure 2.1, chapter 2, of this paper. In this dissertation, we refine certain parts of this procedure and the two areas in particular that we have looked at are: (1) filtering a large set of policy scenarios (Background Set), that could be a continuum, to form a smaller set (Foreground Set), and (2) further reducing the smaller set to form a solution set of policy scenarios. (The generic terms "Background Set" and "Foreground Set" are defined in section 2.1 of chapter 2.) The main objectives of this study were therefore mainly twofold and are as follows: (1) to determine what MCDM methods are relevant to natural resources management (using water as a case study), and (2) to investigate how these methods need to be adopted for use in an interactive DSS. We address the first objective by surveying the literature in an attempt to identify potential MCDM approaches that are suitable to (i) reduce a large set of alternatives, analogous to the Background Set, to a more manageable smaller set, analogous to the Foreground Set of alternatives, and (ii) refine this Foreground Set in order to present the DMs with a solution set of alternatives from which University of Cape Town they will make their final selection. The literature has until now not dealt explicitly with these two issues and we had to adapt certain MCDM approaches, many of which have been developed in a linear programming context, to suit our purposes.

Annotation:
According to the IPCC (2007) fourth assessment report, small islands and coastal communities have a set of characteristics that makes them very vulnerable to climate change impacts, mainly sea-level rise and storm surges.
Coastal hazards including inundation, salinisation of the water supply, and erosion threaten vital infrastructure that support coastal communities.
Although Canada has the longest coastline in the world, little work has been done on impacts of climate change and adaptation to these impacts in the Canadian coastal zones. This research is part of an International Community-University Research Alliance (ICURA) C-Change, project to develop a multicriteria decision evaluation and support for the systems analysis of adaptation options for coastal communities toward adapting to environmental changes. This study estimates the vulnerability of coastal communities with respect to their environmental, economic, social, and cultural dimensions. It also applies a group version of the Analytical Hierarchy Process for identifying decisions that various stakeholders make on suggested adaptation strategies. This study develops a methodological framework that is applicable to various coastal and small island contexts. The application of the proposed framework is further discussed in a case study conducted on the communities of Charlottetown, Prince Edward Island (PEI), and Little Anse on Isle Madame, Nova Scotia. Specifically, the state of the Little Anse breakwater is analyzed and new adaptation options are presented and evaluated.
This research has illustrated and applied a process of decision evaluation and support that explicitly engages multiple participants and critieria in complex problems situations involving environmental change in coastal communities.

Annotation:
Continuous development has been occurring in the area of decision support systems. Modern systems focus on applying decision models that can provide intelligent support to the decision maker. These systems focus on modelling the human reasoning process in situations requiring decision. This task may be achieved by using an appropriate decision model. Multicriteria decision making (MCDM) is a common decision making approach. This research investigates and seeks a way to resolve various issues associated with the application of this model. MCDM is a formal and systematic decision making approach that evaluates a given set of alternatives against a given set of criteria. The global evaluation of alternatives is determined through the process of aggregation. It is well established that the aggregation process should consider the importance of criteria while determining the overall worth of an alternative. The importance of individual criteria and of sub-sets of the criteria affects the global evaluation. The aggregation also needs to consider the importance of the sub-set of criteria. Most decision problems involve dependent criteria and the interaction between the criteria needs to be modelled. Traditional aggregation approaches, such as weighted average, do not model the interaction between the criteria. Non-additive measures such as fuzzy measures model the interaction between the criteria. However, determination of non-additive measures in a practical application is problematic. Various approaches have been proposed to resolve the difficulty in acquisition of fuzzy measures. These approaches mainly propose use of past precedents. This research extends this notion and proposes an approach based on similarity-based reasoning. Solutions to the past problems can be used to solve the new decision problems. This is the central idea behind the proposed methodology. The methodology itself applies the theory of reasoning by analogy for solving MCDM problems. This methodology uses a repository of cases of past decision problems. This case base is used to determine the fuzzy measures for the new decision problem. This work also analyses various similarity measures. The illustration of the proposed methodology in a case-based decision support system shows that interactive models are suitable tools for determining fuzzy measures in a given decision problem. This research makes an important contribution by proposing a similarity-based approach for acquisition of fuzzy measures.

Annotation:
The shift in mindset of decision makers, from maintenance being a “necessary
evil” and “cost centre” to a “profit contributor” in manufacturing companies has
driven outsourced maintenance suppliers to employ value-centric approaches in
order to design more effective maintenance programs. A value assessment for
maintenance outsourcing must facilitate the trade-off between cost-centric and
value-centric approaches to enable the maintenance service providers to design
more effective maintenance organizations. This assessment should also help
the customers in a well informed decision making in outsourcing their
maintenance function in order to add value to their businesses. Therefore the
aim of this research is to develop a decision making framework for maintenance
outsourcing based on the assessed customer-value of outsourced maintenance
services. Cont/d.

Includes bibliographical references.Poverty eradication as a policy issue has received significant attention since the promulgation of the South African National Development Plan (NDP). The NDP envisages that by 2030 poverty should be eradicated. To do this government must accurately target their interventions ensuring that the intended population benefits from the actual poverty eradication intervention. With the evolution of systems and processes in the Science and Technology industry over the past two decades, the integration of Geographical Information Systems (GIS) and MCDM techniques has achieved encouraging results within different planning domains (Lidouh, 2012: 2). This research paper presents a vector - based GIS - MCDM methodology that integrates both Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) and COmplex PRoportional Assessment (COPRAS) within a GIS environment. This integration is facilitated through the use of loose coupling within the ArcGIS 10.2 environment.

A aplicação de metodologias de análise multicriterial já é utilizada há décadas para análise de investimentos de alto capital, e continuam sendo ferramentas de referência para tomadas de decisão nas organizações em todo mundo. Contudo, não só grandes investimentos são influênciados por variáveis que interagem entre si e precisam ser levadas em consideração numa tomada de decisão acertada. No dia-a-dia de uma empresa, em diversos setores, decisões de menores impactos são tomadas sem que um método de análise multicriterial seja adotado para tal escolha. No entanto, quando somadas, essas decisões de menores impactos acabam por influênciar no resultado geral da empresa. O objetivo dessa pesquisa foi desenvolver um método ágil de análise multicriterial que possa ser facilmente adaptado e aplicado em processos operacionais dinâmicos, comuns na rotina de grandes empresas, auxiliando nas tomadas de decisões em níveis mais baixos da organização. O método proposto foi aplicado em dois diferentes processos de uma empresa multinacional do setor de mineração. No primeiro processo foi avaliada a priorização da implantação de projetos de melhoria, onde ideias de empregados são transformadas em projetos que geram ganhos para a empresa. No segundo processo de programação da manutenção, o método auxiliou na priorização da execução de serviços de manutenção quando existem limitações de recursos. O método proposto combina a utilização de ferramentas de diversos métodos já consagrados com a adoção de soluções criativas para atender a dinamicidade dos processos avaliados.Multicriteria analysis methodologies have been used for decades to analyze substantial capital investment alternatives, and continue to be a reference tool for capital budgeting decision making in organizations. Small investments are also influenced by several variables that need to be taken into account in assertive decision making. Minor impacts decisions are taken without using a method of multicriteria analysis and when all this decisions are combined, they influence the overall result of the company. The objective of this research is to develop a multi-criteria analysis method agile that can be easily adapted and applied to different operation dynamic process, usual in large businesses routine, helping decision making at lower levels of the organization. The proposed method was applied in two different processes of a multinational company in the mining sector. In the first case the process of prioritization projects method was studied, where ideas of employees were transformed into smaller projects that generate profit for the company. In the second case, maintenance scheduling, the method helped to prioritize the execution of maintenance services when there are resource limitation. The proposed method combines tools of renowned methods with creative solutions to help a decision making in dynamics processes.

This study is conducted with the aims to develop a new ranking method for multi-criteria decision making problem with conflicting criteria. Such a problem has a set of Pareto solutions, where the act of improving a value of one solution will result in depreciating some of the others. Thus, in this type of problem, there is no unique solution. However, out of many available options, the Decision Maker eventually has to choose only one solution. With this problem as the motivation, the current study develops a compromise ranking algorithm, namely a trade-off ranking method. The trade-off ranking method able to give a trade-off solution with the least compromise compared to other choices as the best solution. The properties of the algorithm are studied in the thesis on several test cases. The proposed method is compared against several multi-criteria decision making methods with ranking based on the distance measure, which are the TOPSIS, relative distance and VIKOR. The sensitivity analysis and uncertainty test are carried out to examine the methods robustness. A critical criteria analysis is also done to test for the most critical criterion in a multi-criteria problem. The decision making method is considered further in a fuzzy environment problem where the fuzzy trade-off ranking is developed and compared against existing fuzzy decision making methods.

Hoy en día, los controladores proporcionales integrales y proporcionales integrales
derivativos son los algoritmos de control más utilizado en la industria. Por otra parte, los
controladores fraccionarios han recibido atención recientemente, por parte de la comunidad
científica y desde el punto de vista industrial. Debido a esto, en esta tesis algunos de los
escenarios implican la sintonización de estos controladores mediante el procedimiento de diseño
mediante la optimización multi-objetivo. Este procedimiento se centra en proporcionar un
equilibrio razonable entre los objetivos en conflicto y brinda al diseñador la posibilidad de
apreciar la comparación de los objetivos de diseño.
Esta tesis se divide en tres partes. La primera parte, presenta los fundamentos del sistema de
control y discusión de los diferentes compromisos: entre los modos de operación servo /
regulación y del rendimiento / robustez. Por otro lado, se ha proporcionado un marco
conceptual acerca de la optimización multi-objetivo.
La segunda parte, introduce la solución de Nash como una técnica de selección multi-criterio,
para seleccionar un punto del frente de Pareto, que represente el mejor compromiso entre los
objetivos de diseño. Esta solución es una selección semi-automática escogida en la
aproximación del frente de Pareto y ofrece un buen compromiso entre los objetivos de diseño.
Luego, se presenta el Multi-stage approach para el proceso de optimización multi-objetivo. Este
enfoque implica dos algoritmos: un algoritmo determinista y algoritmo evolutivo. En el cual
ambos algoritmos se complementen entre sí a pesar de sus desventajas y mejoran los resultados
de la optimización en términos de convergencia y precisión. Además, se introduce el objetivo
basado en la fiabilidad, en la descripción del problema multi-objetivo, este se utiliza para medir
la degradación del rendimiento. Vale la pena mencionar que, debido a la existencia de
incertidumbres en el diseño y fabricación, teniendo este objetivo de diseño le dará otra
perspectiva al diseñador en el mundo real. Con el fin de validar el método, dos casos de
estudios se ha considerado, el problema de control de la caldera (The Boiler Control
Benchmark) para la sintonización de controladores y como segundo caso, una pila Peltier nolineal.
Por último, la tercera parte de esta tesis, presentan las contribuciones a la sintonización de
controladores. En primer lugar, se propone un conjunto de reglas de sintonía basado en la
solución de Nash para un controlador proporcional-integral, en donde la robustez / rendimiento
han sido considerados. Por otra parte, como un segundo caso se presenta las reglas de sintonía
para un controlador proporcional-integral-derivativo, donde se han considerado el compromiso
de robustez/rendimiento y los modos de operación servo / regulación. Además, se proponen
reglas de sintonía para el controlador proporcional-integral-derivativo-fraccional-orden

Moreover, the fractional controllers have received attention recently for both, the research community and from the industrial point of view. Owing to this, in this thesis some of the scenarios involve the tuning of these controllers by using the Multiobjective Optimization Design procedure. This procedure focuses on providing reasonable trade-off among the conflictive objectives and brings the designer the possibility to appreciate the comparison of the design objectives. This thesis is divided in three parts. The first part, presented the fundamentals of the control system showing and discussing the different trade-offs between performance/robustness and servo/regulation operation modes. On the other hand a background on multi-objective optimization has been provided. The second part, introduces the Nash solution as a multi-criteria decision making technique, to select a point from the Pareto front that represent the best compromise among the design objective. This solution provides a semi-automatic selection from the Pareto front approximation and offers a good trade-off between the goal objectives. Hereafter, a Multi-stage approach for the multi-objective optimization process is presented. This approach involves two algorithms: a deterministic and evolutionary algorithm. In which both algorithms complement each other in despite of their drawbacks and improve the results of the overall optimization in terms of convergence and accuracy. Further, the introduction of reliability based objective into the multi-objective problem is carried out, to measure the performance degradation. It is worthwhile to mention that, due to the existence of uncertainties in real-world designing and manufacturing having this design objective will give another perspective to the designer. In order to validate the approach, two different case studies has been considered, the Boiler control problem for controller tuning and as second case, a non-linear Peltier Cell. Finally, the third part of this thesis, the contributions on controller tuning have been presented. First, a set of tuning rules based on the NS for a proportional-integral (PI) controller have been devised, where the robustness/performance trade-off have been considered. Moreover, as a second case it is presented a tuning for proportional-integral-derivative controller where the trade-off of the performance/robustness and servo/regulation operation mode has been considered. Moreover, the fractional-order-proportional-integral-derivative controller is tuned by using the Multi-stage approach for the MOO process.

Awarded by:University of New South Wales. School of Built Environment, 2002. http://handle.unsw.edu.au/1959.4/33239.
Annotation:
The research presented in this Thesis is primarily concerned with the field of Geographical Information Systems (GIS) - specifically, the business applications of the technology. The empirical problem addressed is the selection of branch banks as candidates for closure using the network of branch banks of the Commonwealth Bank of Australia in the Sydney metropolitan region as the case study. Decisions to close branches are made by the Bank on the basis of performance indicators that are essentially financial. In this research, however, an alternative approach is adopted: the problem is addressed using a set of spatial criteria. Following the deregulation of the finance industry in the 1980's and the rapid introduction of new electronic channels for delivering financial services, the major banking institutions have been engaged in a process of reorganising their networks of branch banks. The most visible manifestation of this has been the ongoing and widespread closure of branches. Selecting branch banks for closure is a typical example of a complex semi-structured multi-dimensional, multi-criteria, decision-making problem. It has been well documented in previous research that Multi-Criteria Decision-Making (MCDM) models are the most appropriate ones for solving problems in this particular domain. The identification of branches for closure is also characterised by a significant spatial dimension. Decisions are based on a consideration of a number of geographical criteria and various forms of spatial analysis may be involved. An appropriate technology to assist with solving decision-making problems with a significant spatial dimension is a Spatial Decision Support System (SDSS). Most SDSS have been based on the integration of Geographical Information Systems (GIS) technology with analytical models that are proven to be best suited to specific decision-making problems and this is the approach adopted in this research. The prototype MCBC-SDSS (Multi-Criteria Branch Closure SDSS) developed here is based on the integration through the loose coupling of the ArcView GIS software with the Criterium DecisionPlus (CDP) software, which contains the suite of non-spatial analytical models that provide the analytical capability for solving multi-criteria problems. ArcView GIS is used as the engine that drives the system and to provide the analytical and display facilities to support the spatial data involved. Two MCDM models from the CDP software are used to support the decision-making analysis - the Analytical Hierarchy Process (AHP) and Simple Multi-Attribute Rating Technique (SMART). The integration of GIS with the MCDM models is based on a considerable amount of software enhancement, interface development, and computer programming. The development of the integrated system is designed to create an intelligent and user-friendly SDSS, the application of which, from the user's perspective, is a seamless operation. The success of the MCBC-SDSS is demonstrated by its application to identify candidates for closure among the 197 branches of the CBA in the Sydney metropolitan area in 2000 - the year when the building of the database for the research had been completed. The analysis is based purely on spatial considerations that have been gleaned from a major review of the literature that previous researchers have identified as affecting branch viability and performance. A set of 17 spatial variables was used as the criteria in the MCDM models. The criteria are organised in two blocks: the first includes 9 criteria relating to the characteristics of demand for branch service in the branch trade areas ('catchment area' specific criteria) while the second includes 8 criteria relating to aspects of supply provided by the existing branches in their location ('location specific' criteria). Using the developed approach, the MCBC-SDSS has been used directly to compare alternatives against criteria, not only spatial based but also financial ones, thus providing a basis for identifying the best choices regarding branch closure. The steps in the preparation of the data and the iterative procedure for implementing the MCDM models are explained and illustrated. This involves building the initial evaluation matrix, normalising the raw criteria scores, assigning weights to the criteria, and calculating priorities. Based on these, the AHP and SMART models then calculate a decision score for each branch that is used as the basis for creating the preference ranking of the branches. In this, branches with a high rank score based on the combined weighted contribution of the 17 criteria are considered to be operationally viable. On the other hand, branches with the lowest rank scores are considered as potential candidates for closure. The preference rankings generated by the models have been tested to examine their robustness in terms of the validity of criteria and their weights used in the decision analysis. Sensitivity analysis has been conducted, the results of which show that the preference rankings are stable. Different approaches have been used to validate the initial criteria, and analyse their contribution to the ranking of branch banks for closure. These help identify critical spatial variables among the 17 initial criteria selected, and suggest that some of the criteria initially selected could be deleted from the criteria list used to generate the preference rankings without substantially affecting the results. The reasonableness of the resulting preference ranking has been further demonstrated from analyses based on changing criteria weights and alternatives. The research successfully demonstrates one of the ways of enhancing the functionality of a GIS through its integration with non-spatial analytical models to develop a SDSS to aid solving decision-making problems in the selected domain. Given that to date there has been relatively few applications of SDSS similar to that developed in this research to real world decision-making problems, the procedure adopted makes it suitable for decision-making in a range of other service business applications characterised by a significant spatial dimension and multiple outlets including shopping centres, motor car dealerships, restaurant and supermarket chains. Instead of just providing solutions, however, the SDSS-based analysis in this research can better be thought of as adding value to spatial data that forms an important source of information required by decision-makers, providing insight about the situation, uncertainty, objectives, and trade-offs involved in reaching decisions, and being capable of generating alternative scenarios based on different inputs to the models that may be used to identify recommended courses of action. It can lead to better and more effective decision-making in institutions involving multi-outlet retail and service businesses and hence enables both integrated data analysis and modelling while taking multiple criteria and decision-makers' preferences into consideration.

Decisions among alternatives that do not fit rigorous numerical frameworks are common. Such decisions, in which the various aspects of the alternatives are considered simultaneously, are called a tradeoff studies. Tradeoff studies may be more common than optimization problems, but are not generally formalized in written form.Tradeoff studies are broadly recognized and mandated as the method for considering many criteria simultaneously. They are the primary method for making a decision among alternatives listed in the Software Engineering Institute's Capability Maturity Model Integration (CMMI) Decision Analysis and Resolution (DAR) process.The field of Decision Making can explain why the mechanics of tradeoff studies are approached with underconfidence, and can also help eliminate biases from the tradeoff process. Many conclusions obtained from Judgment and Decision Making (JDM), Cognitive Science and Experimental Economics can be used to shed light on various aspects of the tradeoff process. Of course, since many experiments were designed to reveal truths about choice at a basic level, they do not exactly model the processes of tradeoff studies. The technique used to compare the basic experiments and tradeoff studies will be abstraction.Abstraction noun 1. a general concept formed by extracting common features from specific examples, 2. the process of extracting the underlying essence.What follows is a union of the fields of tradeoff studies and cognitive decision making. Because these two areas have never before been explicitly unified, I have produced some unfinished areas in which specific research needs to be done. At this stage, the work of unification must necessarily be conducted at an abstract level.

Annotation:
Decision making is an essential activity for humans and often becomes complex in the presence of uncertainty or insufficient knowledge. This research aims at estimating preferences using pairwise comparisons. A decision maker uses pairwise comparison when he/she is unable to directly assign criteria weights or scores to the available options. The judgments provided in pairwise comparisons may not always be consistent for several reasons. Experimentation has been used to obtain statistical evidence related to the widely-used consistency measures. The results highlight the need to propose new consistency measures. Two new consistency measures - termed congruence and dissonance - are proposed to aid the decision maker in the process of elicitation. Inconsistencies in pairwise comparisons are of two types i.e. cardinal and ordinal. It is shown that both cardinal and ordinal consistency can be improved with the help of these two measures. A heuristic method is then devised to detect and remove intransitive judgments. The results suggest that the devised method is feasible for improving ordinal consistency and is computationally more efficient than the optimization-based methods. There exist situations when revision of judgments is not allowed and prioritization is required without attempting to remove inconsistency. A new prioritization method has been proposed using the graph-theoretic approach. Although the performance of the proposed prioritization method was found to be comparable to other approaches, it has practical limitation in terms of computation time. As a consequence, the problem of prioritization is explored as an optimization problem. A new method based on multi-objective optimization is formulated that offers multiple non-dominated solutions and outperforms all other relevant methods for inconsistent set of judgments. A priority estimation tool (PriEsT) has been developed that implements the proposed consistency measures and prioritization methods. In order to show the benefits of PriEsT, a case study involving Telecom infrastructure selection is presented.

Notre thèse est consacrée à l’étude des méthodes de rangements multicritères dans le cadre de la problématique de tri.
Dans un problème de tri une personne, appelée décideur, désire assigner un objet, appelé action, à des catégories prédéfinies. Des problèmes de tri surgissent régulièrement dans la vie de tous les jours. Par exemple, un médecin ausculte son patient et sur base des symptômes observés, il assigne son patient à une catégorie de pathologies. Ainsi, le médecin peut prescrire un traitement approprié. Par ailleurs, on catégorise les cyclones tropicaux en fonction de leur vitesse, pression superficielle et de la hauteur de marée. En fonction de la catégorie du cyclone, des dégâts éventuels peuvent être prédits et des mesures de protection adéquates devront être prises.
Dans un problème de tri, un décideur regroupe ainsi les actions qu’il considère similaires, à des fins descriptives, organisationnelles ou préventives. Nous supposerons en outre que le décideur exprime une relation de préférence entre les classes préalablement définies.
D’autre part, les méthodes de rangement permettent de ranger les actions de la meilleure à la moins bonne. Nul étudiant ne peut nier l’existence des " rankings " d’universités. Une société ordonne les candidats à l’issue d’un entretien d’embauche. Une société désire par ailleurs établir des partenariats avec les fournisseurs les plus performants. Nous sommes tous confrontés à cette tâche délicate de ranger les actions de la meilleure à la moins bonne. Les méthodes d’aide à la décision proposent des techniques permettant à un décideur d’obtenir un rangement d’actions.
L’objectif de cette thèse est d’étudier la possibilité de résoudre des problèmes de tri à l’aide de méthodes de rangement. L’approche adoptée est de ranger une action particulière par rapport à des normes ou profils définissant les catégories. L’assignation de l’action sera dès lors basée sur sa position dans ce rangement particulier.
Quelles sont les hypothèses nécessaires pour un tel modèle ?Ces méthodes présentent-elles un biais ou ont-elles d’autres avantages par rapport aux méthodes de tri existantes? Est-il préférable de modéliser les catégories à l’aide de critères même si celles-ci ne présentent pas de relation de préférence ?Dans cette thèse nous donnerons des premiers éléments de réponse en développant de nouvelles méthodes de tri basées sur des méthodes de rangement existantes.

Humanitarian relief and aid organizations all over the world implement efforts aimed at recovering from disasters, reducing poverty and promoting human rights. The purpose of this dissertation is to develop a series of quantitative decision models to help address some of the challenges faced by humanitarian logistics.
The first study discusses the development of a spreadsheet-based multicriteria scheduling model for a small development aid organization in a South American developing country. Development aid organizations plan and execute efforts that are primarily directed towards promoting human welfare. Because these organizations rely heavily on the use of volunteers to carry out their social mission, it is important that they manage their volunteer workforce efficiently. In this study, we demonstrate not only how the proposed model helps to reduce the number of unfilled shifts and to decrease total scheduling costs, but also how it helps to better satisfy the volunteers’ scheduling preferences, thus supporting long-term retention and effectiveness of the workforce.
The purpose of the second study is to develop a decision model to assist in the management of humanitarian relief volunteers. One of the challenges faced by humanitarian organizations is that there exist limited decision technologies that fit their needs while it has also been pointed out that those organizations experience coordination difficulties with volunteers willing to help. Even though employee workforce management models have been the topic of extensive research over the past decades, no work has focused on the problem of managing humanitarian relief volunteers. In this study, we discuss a series of principles from the field of volunteer management and develop a multicriteria optimization model to assist in the assignment of both individual volunteers and volunteer groups to tasks. We present illustrative examples and analyze two complementary solution methodologies that incorporate the decision maker's preferences and knowledge and allow him/her to trade-off conflicting objectives.
The third study discusses the development of a decision model for the procurement of goods in humanitarian efforts. Despite the prevalence of procurement expenditures in humanitarian efforts, procurement in humanitarian contexts is a topic that has only been discussed in a qualitative manner in the literature. In our paper, we introduce a two stage decision model with recourse to improve the procurement of goods in humanitarian relief supply chains and present an illustrative example. Conclusions, limitations, and directions for future research are also discussed.Ph. D.

Annotation:
For many decisions validation of their outcomes is invariably problematic to objectively assess. Therefore to aid analysis and validation of decision outcomes, approaches which provide improved traceability and more semantically meaningful measurements of the decision process are required. Hence, this research investigates traceability, transparency, interactivity and auditability to improve the decision making process. Approaches and evaluation measures are proposed to facilitate a richer decision making experience. Multi-Criteria Decision Analysis (MCDA) seeks to determine the suitability of alternatives of a goal with respect to multiple criteria. A key component of prominent MCDA methods is the concept of pairwise comparison. For a set of elements, pairwise comparison enables an accurate and transparent extraction and codification of a decision maker’s preferences, though facilitating a separation of concerns. From a set of pairwise comparisons, a ranking of the elements under consideration can be calculated. There are scenarios when a set of pairwise comparisons undergo alteration, both for individual and multiple decision makers. A set of measures of compromise are proposed to quantify the alteration that a set of pairwise comparisons undergo in such scenarios. The measures seek to provide a decision maker with meaningful knowledge regarding how their views have altered. A set of pairwise comparisons may be inconsistent. When inconsistency is present it adversely affects a ranking of the elements derived from the comparisons. Moreover inconsistency within pairwise comparisons used for consideration of more than a handful of elements is almost inevitable. Existing approaches that seek to alter a set of comparisons to reduce inconsistency lack traceability, flexibility, and specific consideration of alteration to the judgments in a way that is meaningful to a decision maker. An approach to inconsistency reduction is proposed that seeks to address these issues. For many decisions the opinions of multiple decision makers are utilized, either to avail of their combined expertise or to incorporate conflicting views. Aggregation of multiple decision makers’ pairwise companions seek to combine the views of the group into a single representation of views. An approach to group aggregation of pairwise comparisons is proposed that models compromise between the decision makers, facilitates decision maker constraints, considers inconsistency reduction during aggregation and dynamically incorporates decision maker weights of importance. With internet access becoming widespread being able to garner the views of a large group of decision makers’ views has become feasible. An approach to the aggregation of a large group of decision makers’ preferences is proposed. The approach facilitates understanding regarding both the agreement and conflict within the group during calculation of an overall group consensus. A Multi-Objective Optimisation Decision Software (MOODS) prototype tool has been developed that implements both the new measures of compromise and the proposed approaches to inconsistency reduction and group aggregation.

Resumo: Long Term Evolution (LTE), um padrão desenvolvido pelo 3rd Generation Partnership Project (3GPP), é atualmente a principal tecnologia 4G, provendo convergência tecnológica para esta geração de sistemas de comunicação celular. As redes LTE prometem velocidades de transmissão de dados em torno de 100 Mbps no canal de descida. Para esta alta taxa de transferência de dados, é necessário otimizar o uso dos recursos de rede. A tecnologia LTE utiliza técnicas de agendamento para a alocação de recursos de rádio com base nas condições do canal de comunicação. Este trabalho apresenta um algoritmo customizável para agendamento de dados multi-usuário no canal de descida das redes LTE que pode priorizar diferentes tipos de serviços selecionados. O esquema de agendamento proposto é uma versão modificada do agendador Proportional Fairness, que usa a técnica Analytic Hierarchy Process (AHP). Isto permite agregar critérios de desempenho para melhorar a alocação de recursos com base nas condições de tráfego gerais e um conjunto de prioridades de serviços predefinidos. A abordagem para essa customização é atribuir pesos para determinados parâmetros utilizados no processo de alocação de recursos, modificando assim a importância relativa desses parâmetros, criando uma hierarquia de critérios. É possível ainda adicionar critérios para diferentes tipos de dados através de matrizes de comparação. A matriz de comparação quantifica o julgamento do tomador de decisão no que se refere à importância relativa dos diferentes critérios. Assim, o agendador pode se tornar flexível e adaptável a diferentes cenários de tráfego. Exemplos são apresentados onde o tráfego de vídeo é priorizado
Abstract: Long Term Evolution (LTE), a standard developed by the 3rd Generation Partnership Project (3GPP), is currently the 4G mainstream technology, providing technology convergence for this generation of cellular communication systems. LTE networks promise data transmission rates of 100 Mbps in the downlink channel. For this high throughput it needs to optimize the use of network resources. LTE uses scheduling techniques for radio resource allocation based on communication channel conditions. This paper presents a customizable algorithm for multi-user data scheduling in the LTE downlink channel that can prioritize selected types of services. The proposed scheduling scheme is a modified version of the proportional fairness scheduler that uses Analytic Hierarchy Process (AHP) techniques. This allows to aggregate performance criteria to improve resource allocation based on general traffic conditions and a set of predefined service priorities. The approach for this customization is to assign weights to certain parameters used in the resource allocation process, thus modifying the relative importance of these parameters and creating a hierarchy of criteria. It is possible to add criteria for different types of data through comparison matrices. A comparison matrix quantifies the judgement of the decision maker with respect to the relative importance of different criteria. Thus the scheduler can be made flexible and adaptive to different traffic scenarios. Examples are given where video traffic is prioritized

L'évaluation des bénéfices et des risques des médicaments joue un rôle central dans la protection de la santé publique. Cependant, et de l’avis général, il apparaît que cette évaluation nécessite d’être revisitée. En 2010, aucun examen n’avait encore été effectué pour déterminer si les méthodes disponibles pouvaient être appliquées à l’évaluation de la balance bénéfice-risque des médicaments dans le cadre réglementaire, et si oui à quel point elles seraient applicable. L’objectif de cette thèse a donc été d’identifier la ou les méthodes pouvant être théoriquement utilisées pour ce type d’évaluation, puis de les confronter à des cas concrets afin d’en déterminer leur applicabilité. Les résultats de l’évaluation des méthodes ont montrés que les méthodes les plus appropriées sont la méthode d’aide à la décision multicritère (MCDA) ainsi que ses variantes. Les résultats de l'application pratique de la méthode MCDA ont indiqué que cette méthode peut être utilisé dans les scénarios communs d'enregistrement en Europe. Cependant il convient de noter que cette méthode ne fournit ni une recette « prête à l'emploi » pour exécuter cette évaluation ni une réponse directeThe benefit-risk evaluation of new medicines plays a central role in safeguarding public health. Nevertheless, it seems that the benefit-risk evaluation calls for further improvement. In 2010, no review had been performed of how available benefit-risk assessment methods could be applied for a regulatory benefit-risk assessment and how feasible that would be when facing real-life cases. The objective of this thesis has thus been to identify method(s) that could be theoretically used for such an assessment, and then to confront it/them to real-life cases, in order to determine their applicability. The results of the methods evaluation showed that the most suitable methods for a regulatory benefit-risk assessment of medicinal products are the MCDA method and the MCDA based methods. The results of the practical application of the MCDA indicated that the method could be used for medicinal products registered through a common registration scenario in Europe. However it should be noted that this method provides neither a “ready-made” recipe to perform an assessment nor a direct answer

Resumo: A capacidade de estocagem de grãos instalada nas propriedades rurais no Brasil é baixa, bem como os armazéns, silos e entrepostos comerciais (público ou privado), devido a localizações, tipos e condições físicas, apresentam deficiências no que se refere ao desempenho e suficiência dessa infraestrutura. Assim, esse trabalho procurou abordar o problema de decisão relativo à implantação de um sistema de armazenamento de grãos na propriedade rural, considerando riscos, benefícios, incertezas e alternativas. Para tanto, foi utilizada a metodologia de auxílio multicritério à decisão, de modo a considerar os inúmeros objetivos, consequências, critérios, valores, expectativas e desempenhos das alternativas consideradas. A aplicação do método em uma situação real foi realizada para auxiliar um empresário rural (sojicultura) a decidir qual infraestrutura adotar para armazenar sua produção. Os resultados obtidos foram importantes para melhorar o seu entendimento sobre a problemática considerada, bem como sobre as alternativas existentes e suas respectivas vantagens e desvantagens. Dessa forma, concluiu-se que a metodologia de auxílio multicritério à decisão pode ser uma abordagem útil na implantação de um sistema de armazenagem de grãos na propriedade rural, pois foi capaz de incorporar diversas variáveis e objetivos, bem como os valores do decisor (produtor), fornecendo subsídios para a tomada de decisão e o acompanhamento da eficácia e eficiência da solução adotada
Abstract: The grain storage capacity installed in rural properties in Brazil is low, as well as grain storehouses, silos and commercial warehouses (public or private), because the locations, types and conditions, display gaps with regard to performance and adequacy of such facilities. Thus, this study sought to address the decision problem on the implementation of on-farm grain storage system, taking account of risks, benefits, uncertainties and alternatives. For this purpose, it was adopted the methodology of multicriteria decision aid, in order to consider the many objectives, consequences, criteria, values, expectations and performances of the existing alternatives. The application of the method in a real situation was held to aid a rural entrepreneur (soybean production) to decide what infrastructure to select to store his production. The results were important to improve his understanding of the considered issues, as well as on the alternatives and their advantages and disadvantages. Thus, it was concluded that the methodology of multicriteria decision aid can be a useful approach on implementation of on-farm grain storage system because it was able to incorporate many variables and objectives, as well as the values of the decision maker (producer), supporting decision making and providing informations to monitor the effectiveness and efficiency of the selected solution

Este trabalho apresenta o processo de seleção de estratégia de reconversão industrial de uma pequena refinaria de petróleo no Sul do Brasil através da aplicação de uma modelagem integrada, utilizando um método multicriterial e programação matemática. Neste estudo foram identificadas linhas de negócio potencialmente aplicáveis à realidade da companhia e definido um conjunto de critérios de análise abrangendo as três dimensões da sustentabilidade empresarial: econômica, social e ambiental. Com base na avaliação da importância relativa de cada critério, atribuída por um grupo de decisores, e no desempenho das linhas de negócio em cada um dos critérios, foi aplicado método fuzzy TOPSIS para análise e ordenação das linhas de negócio. As informações resultantes desta análise, juntamente com dados econômicos objetivos, foram utilizadas em um modelo de programação linear inteira para avaliar portfólios viáveis de linhas de negócio, identificando estratégias candidatas à implementação na refinaria. O desempenho global de cada estratégia candidata, obtido mediante agregação dos desempenhos individuais das linhas de negócio e calculado conforme método fuzzy TOPSIS, foi analisado através de ferramentas gráficas, de modo a gerar elementos para subsidiar a seleção da melhor estratégia de reconversão. Os resultados obtidos demonstraram a eficiência da abordagem proposta, no sentido de facilitar o entendimento e a exploração da situação problema e, assim, oferecer um adequado suporte à tomada de decisão.This dissertation presents a selection process of industrial reconversion strategy in a small oil refinery in southern Brazil by applying an integrated modeling approach, using a multicriteria and a mathematical programming method. Potentially performing business lines were identified, as well a set of criteria covering the three dimensions of corporate sustainability: economic, social and environmental. Based on the relative importance evaluation of each criteria given by a group of decision-makers, and on performance of the business lines in each of the criteria, fuzzy TOPSIS method was applied for analysis and sorting of business lines. The information resulting from this analysis, along with objective economic data, were used in integer linear programming model to evaluate effective portfolios of business lines, identifying candidate strategies to implement in the refinery. Fuzzy TOPSIS is used to generate overall performance scores of each candidate strategy, aggregating the individual performance of the business lines. The sustainability assessment was analyzed through graphical tools in order to generate information to support the selection of the best strategy for the industrial reconversion. The results demonstrated the efficiency of the proposed approach to facilitate the understanding and exploitation of the problem situation and thus offer adequate support to decision making.

A competitividade de uma organização e, consequentemente, sua prosperidade perante concorridos mercados, depende muito da capacidade de inovação e aprimoramento de seus produtos/serviços e processos. A procura por melhores padrões de manufatura e serviços prestados aos clientes, além das aplicações de novas técnicas gerenciais, de melhoria contínua, de otimização e de tomada de decisão, têm atraído a atenção das organizações. O esforço criativo humano deve propor abordagens de caráter competitivo, combinando ferramentas e técnicas, conhecidas ou não, a fim de melhorarem seus desempenhos. Assim, o objetivo desta tese foi propor uma estrutura analítica integrando de forma sequencial o processo de melhoria contínua DMAIC e o método de análise multicriterial para tomada de decisão Analytic Hierarchy Process (AHP), com vistas às aplicações em operações de distribuição física de bebidas. Em um primeiro momento, por meio de uma pesquisa bibliográfica, foi proposta uma estrutura geral, denominada Estrutura Analítica DMAIC/AHP, envolvendo as teorias supracitadas. Além disso, com o auxílio de um estudo de caso, foi proposta uma estrutura detalhada para a tentativa de melhoria da operação de distribuição física de bebidas em uma empresa na cidade de Ribeirão Preto. O foco esteve também na oportunidade de se obter maior conhecimento do processo em estudo e melhorar o embasamento para a tomada de decisão. A aplicação da estrutura analítica foi dividida em três fases: fase 1 - definições para o projeto de melhoria; fase 2 - condução do processo de melhoria em si; e fase 3 (denominada metafase) - responsável por monitorar/acompanhar as atividades do projeto. A aplicação em um caso real permitiu a proposta de atividades e ferramentas para entendimento e aperfeiçoamento do processo; além de alternativas de decisão frente aos problemas encontrados; deu embasamento para a tomada de decisão no momento de se implementarem as melhorias e apresentou instrumentos para manutenção e controle das alterações propostas no projeto. Um ganho evidente com a junção das teorias foi que houve um auxílio mútuo entre elas. Dessa forma, o processo de melhoria contínua DMAIC, por meio de suas etapas minuciosas de conhecimentos de processos e de causas de problemas, pôde embasar de forma robusta a definição do modelo hierárquico do AHP, desde o objetivo geral a ser atingido, passando pelos critérios de decisão, até se chegar às alternativas de decisão propostas para o processo em estudo. Por outro lado, como o DMAIC não apresenta um método de tomada de decisão atraente, o AHP pôde auxiliar na tomada de decisão multicriterial de forma mais organizada, consistente e assertiva.The competitiveness of an organization and consequently its prosperity before competitive markets, depends widely on the capacity for innovation and improvement of its products/services and processes. The pursuit for better manufacturing standards and services provided to customers, in addition to the applications of new management techniques, continuous improvement, optimization and decision-making, have attracted attention of organizations. The human creative effort should propose approaches of competitive basis, combining tools and techniques, known or not, in order to improve their performance. Thus, the objective of this thesis was to propose an analytical structure integrating sequentially the process of continuous improvement DMAIC of Six Sigma and the multi-criteria analysis method for decision making Analytic Hierarchy Process (AHP), in order to apply in real cases in beverage industries. At first, through a literature search, it was proposed a general structure, called Analytical Structure DMAIC/AHP, involving the above theories. In addition, with a case study aid, it was proposed a detailed structure attempting to improve the operation of physical distribution for beverages in a company in the city of Ribeirão Preto. The focus was also on the opportunity to gain greater knowledge of the process under study and improve the foundation for decision making. The application of analytical structure was divided into three phases: phase 1 - definitions for the improvement project; phase 2 - implementation of the improvement process itself; and phase 3 (called metaphase) - responsible for monitoring/following the activities of the project. The application in a real case allowed the proposal of activities and tools for the understanding and improvement of the process, as well as possibilities for more alternatives to problems encountered; provided foundation for decision making at the time of implementing the improvements and presented tools for maintenance and control of changes proposed in the project. An obvious gain from the junction of the theories was that there was a mutual aid between them. Thus, the process of continuous improvement DMAIC, through its detailed stages of knowledge of processes and causes of problems could robustly base the definition of the hierarchical model of AHP, since the overall objective to be attained, passing through the decision criteria, until they get to the alternatives of decisions proposed for the process under study. On the other hand, as the DMAIC does not present an attractive method of decision-making, AHP could assist in multi-criteria decision making more organized, consistent and assertive.

The aim of this thesis is to analyze a management problem in the organization Bohemians 1905, a.s. and submit recommendations to the board of the club for strategic choice options how to solve the management problem. The correct formulation of the problem will need to be analyze the current situation, put it in a strategic context and find the cause of the problem. This is done by Kepner-Tregoe methodology, C-E diagram and cognitive map. It will also need to develop objective solutions, design criteria, specify the possible solutions and determine the consequences of various options due to the proposed set of criteria. This is done by the value tree, a combination of multi-criteria evaluation under risk and certainty, probability trees and decision matrices. As a form of multi-criteria evaluation will be used in a specific form of the transfer bridge in the form of aggregated criteria of price/performance ratio of the options that allows create a list of preferred options.

The surveillance of geographic borders and critical infrastructures using limited sensor capability has always been a challenging task in many homeland security applications. While geographic borders may be very long and may go through isolated areas, critical assets may be large and numerous and may be located in highly populated areas. As a result, it is virtually impossible to secure each and every mile of border around the country, and each and every critical infrastructure inside the country. Most often, a compromise must be made between the percentage of border or critical asset covered by surveillance systems and the induced cost. Although threats to homeland security can be conceived to take place in many forms, those regarding illegal penetration of the air, land, and maritime domains under the cover of day-to-day activities have been identified to be of particular interest. For instance, the proliferation of drug smuggling, illegal immigration, international organized crime, resource exploitation, and more recently, modern piracy, require the strengthening of land border and maritime awareness and increasingly complex and challenging national security environments. The complexity and challenges associated to the above mission and to the protection of the homeland may explain why a methodology enabling the design and optimization of distributed detection systems architectures, able to provide accurate scanning of the air, land, and maritime domains, in a specific geographic and climatic environment, is a capital concern for the defense and protection community. This thesis proposes a methodology aimed at addressing the aforementioned gaps and challenges. The methodology particularly reformulates the problem in clear terms so as to facilitate the subsequent modeling and simulation of potential operational scenarios. The needs and challenges involved in the proposed study are investigated and a detailed description of a multidisciplinary strategy for the design and optimization of detection architectures in terms of detection performance and cost is provided. This implies the creation of a framework for the modeling and simulation of notional scenarios, as well as the development of improved methods for accurate optimization of detection architectures. More precisely, the present thesis describes a new approach to determining detection architectures able to provide effective coverage of a given geographical environment at a minimum cost, by optimizing the appropriate number, types, and locations of surveillance and detection systems. The objective of the optimization is twofold. First, given the topography of the terrain under study, several promising locations are determined for each sensor system based on the percentage of terrain it is covering. Second, architectures of sensor systems able to effectively cover large percentages of the terrain at minimal costs are determined by optimizing the number, types and locations of each detection system in the architecture. To do so, a modified Genetic Algorithm and a modified Particle Swarm Optimization are investigated and their ability to provide consistent results is compared. Ultimately, the modified Particle Swarm Optimization algorithm is used to obtain a Pareto frontier of detection architectures able to satisfy varying customer preferences on coverage performance and related cost.

The research entitled "Application of multicriteria method in management decision making: a study on the maintenance of logistics equipment" is a study that proposes a matrix for decision making, considering all the criteria of importance, choosing among the alternatives, the most favorable to the current need. Its general objective is to propose a multicriteria analysis model, as an alternative to support in the management decision making, achieved by the following specific objectives: Define the qualitative and quantitative variables of the process; Express the importance of system variables; Propose the best alternative that meets the needs of the system; Demonstrate the tolerance / flexibility margins of the system and Validate the multicriteria analysis model. The theoretical support of the research was based on bibliographical research, documentary analysis and Focus group instrument, starting from the understanding and characterization of the problem, until reaching the modeling of the weighted matrix providing a numerical index of the criterion evaluation, validated through the action research, in a company of the Polo of Two Wheels, with the purpose of assisting in the process of revaluation of the system of maintenance of logistic equipment, whose purpose is to eliminate line stops due to the unavailability of logistic handling equipment. Regarding the results, it was identified that the expectation of the system could be met with 86% satisfaction of the criteria, as opposed to the one reached by the current operator with 44% attendance. In the first stage of the criterial evaluation, the most compromised proposal with the expected results was alternative C, with capacity to meet 66% of expectations. However, this service capacity is below the target of 86%. In the second stage, with the implementation of several actions to develop the supplier, the best alternative was presented by supplier A (the current operator) with 81%. The research demonstrated that the maximum reach is in the evaluation of the alternatives through Multicriteria Analysis, changing the course of the decision, previously taken with intuitive basis, where the decision maker realized that its limiting was the market, and, in developing the market , made it possible to double the capacity of the current operator
A pesquisa intitulada “Aplicação de método multicritério na tomada de decisões gerenciais: um estudo na manutenção de equipamentos logísticos” constitui-se em estudo que propõe uma matriz para tomada de decisão, considerando-se todos os critérios de importância, elegendo dentre as alternativas, a mais favorável à necessidade em curso. Seu objetivo geral é a propositura de um modelo de análise multicritério, como alternativa para suporte na tomada de decisões gerenciais, alcançado pelos seguintes objetivos específicos: Definir as variáveis quali-quantitativas do processo; Expressar a importância das variáveis do sistema; Propor a melhor alternativa que atenda às necessidades do sistema; Demonstrar as margens de tolerância/flexibilidade do sistema e Validar o modelo de análise multicritério. A sustentação teórica da pesquisa baseou-se na pesquisa bibliográfica, na análise documental e no instrumento Focus group, partindo-se do entendimento e caracterização do problema, até atingir a modelagem da matriz ponderada fornecedora de um índice numérico da avaliação criterial, validada através da pesquisa-ação, em empresa do Polo de Duas Rodas, com o objetivo de auxiliar no processo de reavaliação do sistema de manutenção de equipamentos logísticos, cuja finalidade é eliminar as paradas de linha por indisponibilidade de equipamento de movimentação logístico. No que tange aos resultados, identificou-se que a expectativa do sistema poderia ser atendida com 86% de satisfação dos critérios, contrapondo-se ao atingido pelo operador atual com atendimento de 44%. Na primeira etapa da avaliação criterial, a proposta mais comprometida com os resultados esperados era a alternativa C, com capacidade de atendimento de 66% das expectativas. Porém, essa capacidade de atendimento está abaixo da meta que é de 86%. Na segunda Etapa, com a implantação de diversas ações para desenvolver o fornecedor, a melhor alternativa foi apresentada pelo fornecedor A (o atual operador) com 81%. A pesquisa demonstrou como conclusão que o alcance máximo está na avaliação das alternativas através de Análise Multicritério, mudando-se o curso da decisão, antes tomada com base intuitiva, onde o decisor percebeu que seu limitante era o mercado, e, ao desenvolver o mercado, possibilitou dobrar a capacidade do operador atual.

Annotation:
Building Information Modeling (BIM) is becoming imperative across building disciplines to improve communication and workflow from the first blueprint. Maintenance and facility management is however lagging behind in adoption and research of BIM. Utilizing research-through-design, this study explores BIM-enabled facility management and the critical practice of decision-making at the Celsius building in Uppsala. Contextual design and inquiry were applied to identify and suggest important design features that support decisions related to the task of establishing maximum room occupation. Results show that facility managers can make use of fuzzy multicriteria decision-making and expert heuristics to independently reach conclusions. Important design features were found to heavily rely on the existing building models, where context-view filtered to room capacity data in the existing BIM-system effectively supported the users’ assessment of data. The filtered, aggregated information presented in a simplified mobile format was insufficient for decision-making, suggesting that the building model was more important than initially perceived.

This thesis aimed to investigate the relationship between Multicriteria Decision Making methods and decision strategies used by individuals in the selection process in a specific context. Therefore, as a basis we took the fundamental elements of three multiple criteria methods, PROMETHEE MACBETH and AHP, as well as the decision strategies: additive-compensatory, additive difference, elimination by aspects and conjunctive by Todd and Benbasat (1991), which allowed build six categories of analysis of this study: independent evaluations, dependent evaluations, summations, differences, eliminations and temporary choices. Therefore, a laboratory experiment was conducted in a multi-brand car shop so that the individual could perform the task of choosing an second-hand car independently: with the aid of one of Multicriteria Decision Aid (Visual PROMETHEE, M-MACBETH or TransparentChoice) and without the aid of the system, that is, only with the mind of the individual to guide the decision, being used the verbal think aloud protocol. Thus, 61 experimental subjects participated in the survey. The presentation of the results proved the relationship between two, additive difference and elimination by aspect, out of the four strategies proposed decisions by Todd and Benbasat (1991), since these two strategies were identified in the three systems. However, statistical tests showed a significant difference for the decision strategy elimination by aspect for the SADs TransparentChoice and for additive difference for SADs M-MACBETH and TransparentChoice. The two strategies, elimination by aspect and additive difference for individuals who received the aid only of SAD Visual PROMETHEE are similar to multicriteria decision making methods underlying to this system, in this case, PROMETHEE. Furthermore, we observed that there is a difference in the outcome of the decision when the individual used different SADs, M-MACBETH and Visual PROMETHEE, and that the latter facilitated more the process of choosing consumer goods, in this case, second-hand vehicles. In this context, the SADs served to confirm the assessment of characteristics previously made by the individual s cognitive decision-making system. Furthermore, we found that the individual, when solving a complex decision task, makes a number of connections that are not extended to systems. These findings were noticeable through the tactics that emerged during the verbalization process, i.e., indeterminacies concerning other attributes that were not being considered in the task at hand and compensation trade-offs that each experimental subject performed, which are not allowed by systems. These results suggest specific implications and generate new insights in future research. We believe that the objectives of this thesis were achieved, contributing to the academic and decision-making areas, since the results can serve as guidelines for decision making in the organizational context involving consumer goods purchasing decisions.Esta tese teve como objetivo investigar a relação entre os métodos multicritérios de apoio à decisão e as estratégias de decisão utilizadas pelo indivíduo no processo de escolha em um contexto específico. Para tanto, tomaram-se como base os elementos fundamentais de três métodos multicritérios PROMETHEE, MACBETH e AHP, bem como as estratégias de decisão Compensatória Aditiva, Diferença Aditiva, Eliminação por Aspecto e Conjuntiva de Todd e Benbasat (1991), que permitiram construir as seis categorias de análise deste estudo: avaliações independentes, avaliações dependentes, somatórios, diferenças, eliminações e escolhas temporárias. Assim, foi conduzido um experimento em laboratório em uma loja de comércio de veículos multimarcas de forma que o indivíduo realizasse a tarefa de escolha do veículo usado de modo independente: com o auxílio de um dos Sistemas Multicritério de Apoio à Decisão (Visual PROMETHEE, M-MACBETH ou TransparentChoice) e sem o auxílio do sistema, ou seja, tendo somente a mente do indivíduo como guia da decisão, sendo utilizado o protocolo verbal Think Aloud. Dessa forma, participaram da pesquisa 61 sujeitos experimentais. A apresentação dos resultados comprovou a relação entre duas, Diferença Aditiva e Eliminação por Aspecto, das quatro estratégias de decisão propostas por Todd e Benbasat (1991), uma vez que essas duas estratégias foram identificadas nos três sistemas. Contudo, os testes estatísticos exibiram diferença significativa para a estratégia de decisão Eliminação por Aspecto para o SAD TransparentChoice e para a Diferença Aditiva para os SADs M-MACBETH e TransparentChoice. As duas estratégias de Eliminação por Aspecto e de Diferença Aditiva para os indivíduos que receberam o auxílio somente do SAD Visual PROMETHEE são semelhantes ao método multicritério de apoio à decisão subjacente a esse sistema, nesse caso, o PROMETHEE. Ainda, observou-se que há diferença no resultado da decisão quando o indivíduo utilizou diferentes SADs, o M-MACBETH e o Visual PROMETHEE, e que esse último foi o que mais facilitou o processo de escolha para bens de consumo, nesse caso, veículos usados. Nesse contexto, os SADs serviram para fins de confirmação de avaliações de atributos previamente já realizados pelo sistema cognitivo do decisor. Ademais, constatou-se que o indivíduo, ao resolver uma tarefa de decisão complexa, faz uma série de conexões que não são extensivas aos sistemas. Esses achados foram perceptíveis por meio das táticas que emergiram durante o processo de verbalização, ou seja, indeterminações consoantes a outros atributos que não estavam sendo considerados na tarefa em questão e compensações, trade-offs que cada sujeito experimental realizou, os quais não são permitidos pelos sistemas. Esses resultados sugerem implicações específicas e geração de novos insights em pesquisas futuras. Acredita-se que os objetivos desta tese foram alcançados, contribuindo para a área acadêmica e para área de processo decisório, uma vez que os resultados podem servir de orientações para a tomada de decisão no contexto organizacional envolvendo decisões de compra de bens de consumo.

Annotation:
Le travail de recherche présenté dans cette thèse s'inscrit dans le champ de l'aide multicritère à la décision. Ce champ concerne la décision dans un contexte où les alternatives sont jugées sous divers aspects, souvent conflictuels. Notre travail s'insère dans une approche descriptive et cherche à observer l'effet du conflit multicritère sur les préférences exprimées par le décideur. Dans un premier temps, nous proposons une définition de l'intensité du conflit multicritère entre deux alternatives puis nous nous intéressons aux préférences incomplètes et identifions deux classes de modèles de préférences incomplètes. Notre principale contribution est ensuite d'observer et analyser l'effet du conflit lors du recueil des préférences d'un décideur. Nous avons pour cela conçu et mené deux expérimentations permettant de tester le recueil de préférences à travers des comparaisons par paires, et à travers des matchings. La première expérimentation nous permet de mettre en évidence une forme d'intransitivité de l'indifférence le long des chaînes d'isopréférence. Un fort conflit multicritère conduit les sujets à exprimer des préférences incomplètes. Les résultats obtenus lors de cette expérimentation sont en cours de publication (Deparis et al. [2012]). La seconde expérimentation nous permet de montrer que les asymétries déjà observées dans la littérature en réponse à un bi-matching sont fortement amplifiées par l'effet du conflit multicritère. Nous discutons des implications de ces résultats en termes d'élicitation des préférences. Enfin, nous analysons les résultats expérimentaux au regard de la labilité des préférences qu'ils révèlent. Au-delà de cette contribution, notre thèse permet de mieux comprendre les interactions qui peuvent exister entre les approches normative, descriptive et prescriptive en décision multicritère.

Annotation:
A group health insurance plan is an insurance plan that provides healthcare coverage to a selected group of people. In various countries, group health insurance plans are one of the major benefits offered through employers in the private sector. In recent years, the numbers of group health insurance plans offered in the market of health insurance have been increasing rapidly. This is due to compulsory government policies, which are imposed on employers in the private sector leading to an increasing demand for this insurance plan. Accordingly, employers may face a wide variety of available group health insurance plan alternatives. Despite the fact that employers in the private sector have a crucial and significant role in the health insurance market all over the world, little is known about how employers evaluate and choose group health insurance plans to cover their employees against the payments of benefits as a result of sickness or injury. Therefore, the primary concern in this research is to propose a model to assist employers within the private sector to evaluate alternative group health insurance plans and to select the most appropriate, in order to provide the perfect health care environment for their employees. In this research, a new hybrid Fuzzy Multiple Criteria Decision Making (MCDM) model is proposed for the selection problem. The proposed model tackles some issues that may be associated with the selection of the group health insurance plan, such as modelling uncertainty, studying the dependence among decision attributes, deriving decision attributes importance weights and ranking various alternatives. In the proposed hybrid model, four extension approaches based on the Fuzzy Delphi, Fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL), Fuzzy Group Prioritisation and Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods are developed. Unlike the existing methods, the four proposed approaches, a new extended Fuzzy Delphi (FDE) method, a new extended Fuzzy DEMATEL method, a new Fuzzy Group Prioritisation (FGP) method and a new extended Fuzzy TOPSIS method, consider the importance weight of each member in group decision making since the selection problem needs evaluations from decision makers (DMs) with different levels of expertise and different perceptions. In the literature, there is some work on these methods, but to our knowledge, no research exists that combines these four methods. Moreover, the proposed model might be applied, due to its novelty, to any MCDM problem uncertainty in different. Furthermore, four new prototype decision support tools, termed Fuzzy Delphi Solver, Fuzzy DEMATEL Solver, Fuzzy Group Prioritisation Solver and Fuzzy TOPSIS Solver were developed in this study, based on the concepts of the four proposed approaches, in order to provide user-friendly interfaces for facilitating the application of these approaches. MATLAB software Version R2013a was adopted as a development environment for prototyping these new decision support tools in this study. The tools developed were validated internally by using hypothetical examples and checking the correctness of the results obtained by comparing them to other results generated from other software, such as Microsoft Excel or LINGO V13.0 software. In addition, a practical validation of the proposed hybrid Fuzzy MCDM model was investigated through conducting a case study of the Saudi health insurance industry. The main objectives of the case study were: 1) investigation of the evaluation process of selecting a group health insurance plan, including identifying the selection criteria and alternatives, studying the dependency issue, deriving the criteria weights, and ranking available alternatives; 2) application of the new decision support tools developed. In this case study, a group of nine DMs, Human Resources (HR) managers at nine different private companies in Saudi Arabia, were selected to take part of this case study. Their involvement achieved the first objective of the case study. At the end of the case study, a sensitivity analysis was conducted to indicate the robustness and the reliability of the results obtained. It is concluded that the proposed model is indeed beneficial. Finally, areas for further research were identified.

This thesis presents a framework capable of integrating hard (physics-based) and soft (people-generated) data for the purpose of achieving increased situational assessment (SA) and effective course of action (CoA) generation upon risk identification. The proposed methodology is realized through the extension of an existing Risk Management Framework (RMF). In this work, the RMF’s SA capabilities are augmented via the injection of soft data features into its risk modeling; the performance of these capabilities is evaluated via a newly-proposed risk-centric information fusion effectiveness metric. The framework’s CoA generation capabilities are also extended through the inclusion of people-generated data, capturing important subject matter expertise and providing mission-specific requirements. Furthermore, this work introduces a variety of CoA-related performance measures, used to assess the fitness of each individual potential CoA, as well as to quantify the overall chance of mission success improvement brought about by the inclusion of soft data. This conceptualization is validated via experimental analysis performed on a combination of real- world and synthetically-generated maritime scenarios. It is envisioned that the capabilities put forth herein will take part in a greater system, capable of ingesting and seamlessly integrating vast amounts of heterogeneous data, with the intent of providing accurate and timely situational updates, as well as assisting in operational decision making.

Previous issue date: 2012-03-02The farm production systems, in general, have a certain degree of complexity because it involves a set of variables that the farmer can not always control, and requires a decision-making. The farmer does it considering his rationality based on his objectives, perception, intuition, and information. Even with all these precautions, it s not always easy to make those decisions, and so they often need some support or some tool to assist them, even more when the production systems involve practices and/or organic production processes or with technological innovation. In these cases, the farmer needs to involve a number of internal and external elements to the rural property, interact with nature and know how to use it for the benefit of the production unit. A number of studies have been conducted to improve organic production processes, emphasizing its importance and its social, environmental and economic benefits, and the opportunities it brings. Potato organic production has evolved, but, being a system still in consolidation, it faces bottlenecks in production and in marketing, which should be studied deeper. Following this idea, the study aimed to construct models that aggregate different systems evaluation criteria of organic potato developed by family farmers from southern Rio Grande do Sul state. The study had the participation of a group that has been in the research project Rede de Referência (GRR) of Embrapa Clima Temperado, and another group out of the network (GFRR), associated with Cooperativas Sul Ecológica, Arpa-Sul and Coopar. To evaluate the organic potato system, the study used the decision aid multicriteria tool, which allows the inclusion of the subjective view of the actors involved in the decision-making context through formation of a mental frame of reference (QRM), composed of their personal beliefs, assumptions, values and preferences, through modeling criteria construction in a participatory manner. The study showed, in general, that the models constructed (1-GRR and 2-GFRR) do not differ much from the production practices adopted in each group. Nevertheless, the differences occurred in the levels of impact of actions, and in the establishment of different weights between the models, so the final result in order of preference of evaluation criteria was different. For GRR the criterion potato size was the most important, whereas for GFRR was the criterion production risks. When evaluated with four other organic potato production systems (A, B, C, and D), the two models performances were very close. In model 1 the scores were 72.6; 70.2; 4.1, and 10.9, and in model 2, 71.7; 71.3; 2.7, and 5.0, respectively. In the assessment of each group, the farmers agreed with the results obtained in the models, proving their validity and robustness against the models constructed.
Os sistemas de produção agrícola, de uma forma geral, se caracterizam por certo grau de complexidade, porque envolvem um conjunto de variáveis que nem sempre são controláveis pelo agricultor e que exigem a tomada de decisão, que o faz considerando sua racionalidade, baseado em seus objetivos, percepção, intuição e informação. Mesmo com todas estas precauções, nem sempre são decisões fáceis de serem tomadas e que, muitas vezes, necessitam de algum apoio ou alguma ferramenta que lhes auxilie, ainda mais quando os sistemas de produção envolvem práticas e/ou processos de produção orgânica ou com alguma inovação tecnológica. Nesses casos, o agricultor necessita envolver uma série de elementos internos e externos à propriedade, interagir com a natureza e saber usá-la em benefício da unidade de produção. Estudos vêm sendo realizados para aperfeiçoar os processos de produção orgânica, enfatizando sua importância e seus benefícios sociais, ambientais, econômicos e as oportunidades que ela traz. A produção orgânica de batatas tem evoluído, porém, por ser um sistema ainda em consolidação, enfrenta pontos de estrangulamento na produção e na comercialização, que devem ser estudados com maior profundidade. Neste sentido, o estudo teve por objetivo construir modelos que agreguem os diferentes critérios de avaliação de sistemas de batata orgânica, desenvolvido por agricultores familiares da região Sul do Rio Grande do Sul. Contou com um grupo que vem atuando no projeto de pesquisa Rede de Referência (GRR) da Embrapa Clima Temperado e outro fora da rede (GFRR), associados às Cooperativas Sul Ecológica, Arpa-Sul e Coopar. Para avaliar os sistemas de produção de batata orgânica o estudo utilizou a ferramenta Multicritério de Apoio à Decisão (MCDA), que permite a inserção da visão subjetiva dos atores envolvidos no contexto decisório por intermédio da formação de um quadro de referência mental (QRM), composto por suas crenças pessoais, hipóteses, valores e preferências, através da construção da modelagem criterial de uma forma participativa. O estudo mostrou de uma maneira geral, que os modelos construídos (1-GRR e 2-GFRR), não se diferenciam muito em relação às práticas de produção adotadas em cada um dos grupos. No entanto, as diferenças ocorreram nos níveis de impacto das ações e no estabelecimento de pesos diferentes entre os modelos, de modo que o resultado final, na ordem de preferência dos critérios de avaliação, foi diferente. Para o GRR o critério tamanho da batata foi o mais importante, enquanto que para o GFRR foi o critério riscos de produção. Os dois modelos quando avaliados com outros quatro sistemas de produção de batata orgânica (A,B,C e D), tiveram desempenho muito próximos na avaliação global. No modelo 1, as pontuações foram de 72,6; 70,2; 4,1 e 10,9 e no modelo 2, 71,7; 71,3; 2,7 e 5,0 respectivamente. Na avaliação em cada um dos grupos, os agricultores concordaram com os resultados obtidos nos modelos, comprovando sua validade e robustez frente aos modelos construídos.

Le monde industriel est sans cesse confronté à des problèmes de choix. Une multitude de critères doit être pris en compte dans la résolution de ces derniers. Face à ces situations, les outils d’aide à la décision prennent tout leur sens. Nous utiliserons ici la méthode Analytic Hierarchic Process dans le domaine de la Production et plus particulièrement dans le cadre de l’ordonnancement d’une ligne de production de prothèses cardiovasculaires. Le paramétrage initial de cette méthode fait appel à l’évaluation d’un expert. Bien que ce dernier ait les connaissances nécessaires pour faire un paramétrage convenable, il n’en reste pas moins humain et introduira, même involontairement, une partie subjective dans ses décisions. L’ordonnancement en résultant ne sera donc pas forcément optimal. La réduction de cette subjectivité passe par l’utilisation d’une méta heuristique, de type algorithme génétique, pour améliorer ce paramétrage par l’exploration de solutions voisines à celles proposées par l’expertThe industrial world is continually faced with problems of choices. Multitude of criterion must be taken into account in resolving them. Faced with these situations, the decision making tools give solutions. We will use the Analytic Hierarchy Process in the production field and especially in the scheduling of a cardio vascular prosthesis production line. The initial parameterization of this method involves the evaluation of an expert. Although he has the required knowledge to make a fitting setup, he is no less human and he will bring even unintentionally a subjective part in his decision. The resulting scheduling will therefore not necessarily be optimal. The reduction of the subjectivity can be done using a metaheuristic method, of genetic algorithm type, to improve this parameterization by exploring neighbouring solutions compared to those proposed by the expert

Notre travail de recherche traite la problématique de la conception d’une chaîne logistique multi-niveaux tout en tenant compte du cycle de vie du produit. Par cycle de vie du produit, nous voulons dire la succession des quatre phases de commercialisation que traverse un produit à travers le temps, à savoir : l’introduction, la croissance, la maturité et le déclin. L’objectif est de mette en place un modèle mathématique qui soit fondé sur une analyse approfondie des différents acteurs de la chaîne, selon la phase du cycle de vie du produit.Trois principaux modèles ont été développés dans cette thèse. Chacun fait l’objet d’un chapitre à part entière.Le premier modèle développé vise à concevoir une chaîne logistique de coût minimum, tout en prenant en considération l’efficacité des différents acteurs potentiels calculée selon plusieurs critères (coût, qualité, innovation, qualité du service, délais de livraisons, …), ainsi que sa variation au cours du cycle de vie du produit. Un deuxième modèle a été mis en place pour la conception d’une chaîne logistique durable, tout en prenant en considération le cycle de vie du produit. Dans ce modèle, trois objectifs différents ont été pris en compte à la fois, à savoir, un objectif économique, un objectif environnemental et un objectif social. Dans les deux premiers modèles, nous avons supposé que le produit aura un cycle de vie classique. Cependant, dans la réalité, ceci n’est pas toujours le cas. En effet, quelques produits connaissent des cycles de vie très atypiques et donc très éloignés de la courbe d’un cycle de vie théorique. Pour ce faire, un troisième modèle stochastique a été proposé pour la conception d’une chaîne logistique robuste, tenant compte des différents scénarios du cycle de vie du produitOur research addresses the problem of designing a multi-level supply chain, while taking into consideration the product life cycle. By product life cycle, we mean the succession of the four marketing stages that a product goes through since its introduction to the market and until it will be removed from. All products have a life cycle which can be classified into four discrete stages: introduction, growth, maturity and decline.Depending on the product life cycle phases, and based on a thorough analysis of the different supply chain potential actors, this study aims to establish mathematical models to design an efficient supply chain network. Three main models have been developed in this thesis. The first proposed model aims to design a product-driven supply chain with a minimal total cost, taking into consideration the evaluation of the different potential actors effectiveness, according to several criteria (cost, quality, innovation, quality service, timely delivery, ...).A second model was developed to design of a sustainable supply chain network, taking into account the product life cycle. In this model, three different objectives at the time were considered, namely, an economic objective, an environmental objective and a social objective.In the two previous models, we have assumed that the product has a classical life cycle. However, in the reality this is not always the case. Indeed, some products have very atypical life cycles, whose curves are very different from the classical one. To tackle this problem, in the third part of this thesis, we propose a stochastic model to design a robust supply chain network, taking into account the different product life cycle scenarios
