25. Treatment of uncertainty through the interval smart/swing weighting method: a case study
An increasingly competitive market means that many decisions must be taken, quickly and with precision, in complex, high risk scenarios. This combination of factors makes it necessary to use decision aiding methods which provide a means of dealing with uncertainty in the judgement of the alternatives. This work presents the use of the MAUT method, combined w

26. Reducing incomparability in multicriteria decision analysis: an extension of the ZAPROS method
The ZAPROS method belongs to the Verbal Decision Analysis framework, and it aims at solving decision-making problems in a more realistic way from the decision maker's point of view. Quantitative methods can lead to loss of information when attempting to assign accurate measurements to verbal values. However, the feature exposed can cause a decrease in the co

27. A multicriteria group decision model aggregating the preferences of decision-makers based on electre methods
Grande parte das decisões tomadas em uma organização envolve um grupo de pessoas. Nesse sentido é necessária a existência de metodologias adequadas que dêem suporte à tomada de decisão em grupo, tratando de forma coerente as avaliações e preferências de todos os decisores envolvidos nesse processo. Há duas abordagens utilizadas para decisão em

28. Multiobjective optimization techniques applied to engineering problems
Optimization problems often involve situations in which the user's goal is to minimize and/or maximize not a single objective function, but several, usually conflicting, functions simultaneously. Such situations are formulated as multiobjective optimization problems, also known as multicriteria, multiperformance or vector optimizations. Because multiobjectiv

29. Relative accessibility to urban spaces for pedestrians with mobility constraints / Acessibilidade relativa dos espaços urbanos para pedestres com restrições de mobilidade
The present works focus on the relative accessibility of urban open spaces for pedestrians with mobility constraints, based on the premise that urban open spaces are deficient with regard to the potential mobility of pedestrians and also that the situation can be aggravated by the particular travel conditions of the individuals. Therefore, the urban spaces d

30. A novel approach based on multiple criteria decision aiding methods to cope with classification problems / A Novel Approach Based on Multiple Criteria Decision Aiding Methods to Cope with Classification Problems
This work presents a novel decision making approach developed upon two Multicriteria Decision Aiding (MCDA) classification methods. The classification methods are centered on the concept of prototypes, that are alternatives that serve as class representatives related to a given problem, and have their performance index very dependent upon the choice of value

31. Modelo de decisÃo multicritÃrio aplicado à seleÃÃo de contratados para construÃÃo de subestaÃÃo de energia elÃtrica na CHESF
The dealing of constructions to expand the electrical system has become a challenge for State companies or mixed economy companies. The selection of appropriate suppliers directly impacts on the contractorâs competitiveness. The costs created by the delay in construction ending and the consequent unavailability of the energizing event reduce the expected re

32. Tabela de decisão adaptativa na tomada de decisão multicritério. / Adaptive decision tables on multicriteria decision making.
Esta tese apresenta a formulação de uma extensão da tabela de decisão adaptativa, denominada Tabela de Decisão Adaptativa Estendida (TDAE), que tem por objetivo apoiar aplicações de tomada de decisão multicritério. É implementado um algoritmo de tomada de decisão para a TDAE que incorpora os mecanismos de tabelas de decisão tradicionais, técnica

33. PRIORIZAÇÃO DOS MODOS DE FALHA DE EQUIPAMENTOS UTILIZANDO OS MÉTODOS DE ANÁLISE MULTICRITÉRIO PROMETHEE E FUZZY PROMETHEE / PRIORITIZATION OF FAILURE MODES OF EQUIPMENT USING THE METHODS OF MULTICRITERIA ANALYSIS PROMETHE AND FUZZY PROMETHE
Aiming to meet the criteria of availability and reliability required by the rules of the Brazilian electric sector, energy companies have increased the use of systems for monitoring and diagnosis. This allows the identification of prior evidence of abnormalities in the operational condition of substation equipment, enabling the practice of predictive mainten

34. Modelo de decisÃo multicritÃrio para gestÃo estratÃgica baseado em cenÃrios prospectivos
O produto final deste trabalho apresenta uma modelagem multicritÃrio para gestÃo estratÃgica baseada em cenÃrios prospectivos. Atualmente, o tratamento das questÃes estratÃgicas nas organizaÃÃes, sob a Ãtica da incerteza, assume papel preponderante na busca por vantagens competitivas que garantem a sustentabilidade dos negÃcios. Os modelos de gest�

35. Redes empresariais de negócios orientadas por estratégia definida pela governança supra-empresas: estudo e metodologia de avaliação dos atributos componentes e respectivas influências sobre o poder de competitividade / Business networks oriented by the strategy defined by the supra-enterprises governance
The Business Enterprise Networks are some kind of arrangement which some segments of enterprises and other private and independent organizations, located in different parts of the same productive chain, found to act with common strategy to reinforce their conditions of competing for a bigger place in the market. From the interrelation of its business by a sp

36. MULTICRITERIA OPTIMISATION OF HYDROTHERMAL SYSTEMS OPERATION USING GENETIC ALGORITHMS / OTIMIZAÇÃO MULTICRITÉRIO DA OPERAÇÃO DE SISTEMAS HIDROTÉRMICOS UTILIZANDO ALGORITMOS GENÉTICOS
In Brazil, the planning of the energy operation of the National Interconnected Power System is currently done through a chain of mathematical models designed to optimise the planning according to criterion of minimisation of the expected value of the total operation`s cost. However, since the 2001-2002 energy supply crisis, there was an intensification in th
