UMA REVISÃO DE TRÊS PACOTES DE SOFTWARE DEDICADOS A PROBLEMAS MULTIATRIBUTO

In this work we outline and make a critical discussion of three software packages dedicated to multiattribute models, based on a learning oriented paradigm and involving in its development researchers of INESC-Coimbra. Namely, VIP-Analysis Dias and Clímaco 2000) based on the additive model in order to aggregate value functions, but just requiring imprecise information on the scale coefficients; the IRIS system (Interactive Robustness analysis and parameters Inference for multicriteria Sorting problems - Dias e Mousseau, 2003) dedicated to the sorting problematic, according to a pre-defined set of categories, based on the ELECTRE TRI (Yu 1992), but not requiring the decision maker to fix precise values for all parameters of the method; and, finally , an web interface, called “MATRIX”, for a base of methods including: : Simple Additive Weighting and TOPSIS (Yoon and Hwang, 1995), VIKOR (Duckstein and Opricovic, 1980), ELECTRE I (Benayoun et al., 1966; Roy, 1968), ELECTRE III (Roy, 1978), ELECTRE IV (Roy and Hugonnard, 1982), ELECTRE TRI (Yu, 1992) e AHP (Saaty, 1980).
