Assessing the performance of biogas plants with multi-criteria and data envelop...
Madlener, Reinhard; Antunes, Carlos Henggeler; Dias, Luís C.This paper performs an assessment of 41 agricultural biogas plants located in Austria to determine their relative performance in terms of economic, environmental, and social criteria and corresponding indicators. The comparison of these renewable energy conversion plants is based on two complementary analyses. Data envelopment analysis (DEA) was conducted to provide measures of radial efficiency relative to the...
Managing uncertainty in decision support models
Antunes, Carlos Henggeler; Dias, Luís C.http://www.sciencedirect.com/science/article/B6VCT-4K4WH30-1/1/17f085836a5c5e92684582c95a29eb4d
Supporting groups in sorting decisions: Methodology and use of a multi-criteria...
Damart, Sébastien; Dias, Luís C.; Mousseau, VincentThis paper addresses the situation where a group wishes to cooperatively develop a common multicriteria evaluation model to sort actions (projects, candidates) into classes. It is based on an aggregation/disaggregation approach for the ELECTRE TRI method, implemented on the Decision Support System IRIS. We provide a methodology in which the group discusses how to sort some exemplary actions (possibly fictitious...
Dealing with imprecise information in group multicriteria decisions: a methodol...
Dias, Luís C.; Clímaco, João N.This paper outlines a distributed GDSS suitable to be used over the Internet, based on the VIP Analysis methodology and software. VIP Analysis incorporates complementary approaches to deal with the aggregation of multicriteria performances by means of an additive value function under imprecise information. This proposed GDSS intends to support a decision panel forming a democratic decision unit, whose members w...
IRIS: a DSS for multiple criteria sorting problems
Dias, Luís C.; Mousseau, VincentThis paper presents Interactive Robustness analysis and parameters' Inference for multicriteria Sorting problems (IRIS), a Decision Support System (DSS) designed to sort actions (projects, candidates, alternatives, clients, etc.) described by their performances on multiple criteria into an ordered set of categories defined a priori. It is based on the ELECTRE TRI sorting method, but does not require the decisio...
Shortest path problems with partial information: Models and algorithms for dete...
Dias, Luís C.; Clímaco, João N.In this work we focus on partial information models for the well-known shortest path problem, where we consider multiple instances of values for the parameters that determine the cost of each arc. This allows coping with the uncertainty about the future, the imprecision of data, the arbitrariness of some options, the evolving values of the decision makers (DMs) and/or the multiplicity of DMs (in group decision ...
On computing ELECTRE's credibility indices under partial information
Dias, Luís C.; Clímaco, João N.The ELECTRE family of decision aid methods is a well-known approach to help decision makers (DMs) advance in a decision process. Among the most recent methods in the family, ELECTRE IS, III, and TRI compute fuzzy indices for the credibility of a given action outranking some other. We consider the case when the DMs are unsure which values each parameter should take, which may result from insufficient, imprecise ...
