A cooperative multicriteria group decision aiding tool: a guide tour of the desktop application

Trabalho apresentado na 17th International Conference on Group Decision and Negotiation, 14-18 agosto de 2017, Estugarda, AlemanhaThe main features of the adaptation to a face-to-face cooperative group approach of an interactive decision support tool previously developed with the aim of supporting decisions concerning multicriteria location problems are described. In the application implemented there is no inter-criterion aggregation, so there is no need to reduce the various evaluation dimensions into the same scale. It allows for the individual intervention of several elements of the group, includes some logical tools as well as the possibility of introducing constraints. Furthermore, it propitiates an extensive use of interactive graphics. A guided tour of the desktop application emphasizing its potentialities and limitations is presented.info:eu-repo/semantics/publishedVersio

Methodology and Software for Interactive Decision Support

These Proceedings report the scientific results of an International Workshop on "Methodology and Software for Interactive Decision Support" organized jointly by the System and Decision Sciences Program of IIASA and The National Committee for Applied Systems Analysis and Management in Bulgaria. Several other Bulgarian institutions sponsored the workshop -- The Committee for Science to the Council of Ministers, The State Committee for Research and Technology and The Bulgarian Industrial Association. The workshop was held in Albena, on the Black Sea Coast. In the first section, "Theory and Algorithms for Multiple Criteria Optimization," new theoretical developments in multiple criteria optimization are presented. In the second section, "Theory, Methodology and Software for Decision Support Systems," the principles of building decision support systems are presented as well as software tools constituting the building components of such systems. Moreover, several papers are devoted to the general methodology of building such systems or present experimental design of systems supporting certain class of decision problems. The third section addresses issues of "Applications of Decision Support Systems and Computer Implementations of Decision Support Systems." Another part of this section has a special character. Beside theoretical and methodological papers, several practical implementations of software for decision support have been presented during the workshop. These software packages varied from very experimental and illustrative implementations of some theoretical concept to well developed and documented systems being currently commercially distributed and used for solving practical problems

Wind Energy and Multicriteria Analysis in Making Decisions on the Location of Wind Farms: A Case Study in the North-Eastern of Poland

This chapter presents an investigation of different methods of multicriteria analysis and different rules of proceedings that have to be taken into account for making decision about location of a wind farm with application in the north-eastern (NE) Poland. Ten multicriteria analyses were discussed taking into account the main criteria on which they are based on utility functions (MAUT, AHP, and DEMATEL), relationship outranking (ELECTRE, PROMETHEE, and ARROW-RAYNAUD), distances (TOPSIS), and decision support (BORDA ranking methods and their modified and COPELAND). Taking into account of nine criteria that should be met by the location of 15 wind turbines in Krynki and Szudzialowo communities, the main three criteria (C3, C8, and C9) were found to differentiate location of eight wind turbines (T-6–T-13), according to two variants (I and II). The Borda ranking method proved that from among the two variants considered, the more suitable location of wind turbines is second variant W II than first variant W I. Variant W II had a higher altitude of the terrain (C3) and less risk of impact on birds (C8) and bats species (C9) than variant W I

Operations research as a decision-making tool in the health sector: A state of the art

The contributions of Operations Research (OR) in the healthcare field have been extensively studied in the scientific literature since the 1960s, covering decision support tools with operational, tactical, and strategic approaches. The aim of this article is to analyze the historical development of the application of OR models in healthcare. The application trends for optimization, planning, and decision- making models are studied through a descriptive literature review and a bibliometric analysis of scientific papers published between 1952 and 2016. An upward trend in the usage of operational models is observed with the predominance of resource optimization approaches and strategic decision-making for public health.Los aportes de la Investigación de Operaciones (IO) en el campo de la salud han sido ampliamente estudiados en la literatura científica desde la década de los 60, abarcando el soporte a la decisión en enfoques operacionales, tácticos y estratégicos. Se presenta un resumen del desarrollo histórico de la IO en el campo de la salud y se listan los principales modelos aplicados en los últimos años, identificando el principal enfoque utilizado, y el potencial aporte a la toma de decisiones en el campo de la salud

Multiple Criteria Decision Support; Proceedings of an International Workshop, Helsinki, Finland, August 7-11, 1989

Multiple Criteria Decision Making has been an important and active research area for some 20 years. In the 1970's, research focused on the theory of multiple objective mathematical programming and on procedures for solving multiple objective mathematical programming problems. During the 1980's, a shift in emphasis towards multiple criteria decision support was observed. Accordingly, much research has focused on the user interface, the behavioral foundations of decision making, and on supporting the entire decision-making process from problem structuring to solution implementation. Because of the shift in research emphasis the authors decided to make "Multiple Criteria Decision Support" the theme for the International Workshop, which was held at Suomen Saeaestoepankkiopisto in Espoo, Finland. The Workshop was organized by the Helsinki School of Economics, and sponsored by the Helsinki School of Economics and IIASA, Austria. This volume provides an up-to-date coverage of the theory and practice of multiple criteria decision support. The authors trust that it will serve the research community as well as the previously published Conference Proceedings based on IIASA Workshops

Desenvolvimento de ferramentas de apoio multicritério à decisão em problemas de localização

Tese de doutoramento, Estatística e Investigação Operacional (Análise de Sistemas), Universidade de Lisboa, Faculdade de Ciências, 2014Nesta tese, apresenta-se um Sistema de Apoio à Decisão, desenvolvido e implementado com o objectivo de apoiar a tomada de decisão em problemas de localização bicritério que envolvam preocupações ambientais. O apoio é dado em duas fases interactivas distintas, acreditando que os métodos interactivos são a melhor forma de abordar os modelos multicritério. Na primeira fase, recorre-se a um procedimento de optimização combinatória para obter, de forma progressiva e participativa, qualquer solução não dominada dos modelos de localização bicritério implementados. Nesta primeira fase interactiva, destaca-se a importância de ser possível utilizar um Sistema de Informação Geográfica, integrado no Sistema de Apoio à Decisão, para a obtenção de dados relevantes para os modelos em causa, especialmente aqueles que requerem mais preocupações relativamente aos impactos ambientais. O uso do Sistema de Informação Geográfica, ao longo de todo o processo de decisão, também permite uma visualização apelativa e real das soluções interactivamente obtidas. Na segunda fase, caso seja necessário, usa-se a posteriori uma ferramenta de análise multiatributo para estudar em detalhe as soluções de compromisso provenientes da primeira fase. Esta ferramenta corresponde a uma implementação interactiva simples do método conjuntivo, fazendo uso de um gráfico radar como base do procedimento. A ferramenta proposta pretende contornar o problema da compensação, evitando uma agregação intercritério. O método de análise inerente à ferramenta não exige qualquer transformação ou normalização, de forma a assegurar a comparabilidade entre os critérios. De modo a descrever e a validar as potencialidades e as funcionalidades do SABILOC – o Sistema de Apoio à Decisão desenvolvido e implementado, explora-se um caso de estudo de um problema real relativo à localização de estações de transferência de resíduos.In this thesis, we present a two-phase interactive Decision Support System aimed at supporting decision-making concerning bicriteria location models in which the facilities to be located could have environmental impacts. The decision support is provided through two interactive phases, believing that interactive methods are the best way to deal with multicriteria models. First, a combinatorial optimization procedure to obtain, in a progressive and participatory way, any non-dominated solution of the bicriteria location models implemented, is used. In this first phase, we highlight that a Geographic Information System, embedded into the Decision Support System, can be used to obtain relevant data for the models concerned, especially those considering environmental issues. The Geographic Information System also allows, throughout the decision process, visualizing in an appealing and real way the solutions interactively obtained. Next, if necessary, a multiattribute a posteriori analysis tool could also be employed in order to analyze in detail a set of compromise solutions from the first phase. This one stands for a simple interactive implementation of the conjunctive method making use of a radar chart as basis for the procedure. The tool proposed is intended to circumvent the problem of compensation, avoiding aggregation inter-criteria. To use the method inherent to the tool proposed, it is not required any transformation or normalization to insure the comparability between criteria. In order to describe and validate the potentialities and functionalities of SABILOC – the Decision Support System developed and implemented, we present a case study of a real world problem applied to waste transfer station siting.Fundação para a Ciência e a Tecnologia (FCT, Programa de Apoio à Formação Avançada de Docentes do Ensino Superior Politécnico - PROTEC
