Constructing linguistic versions for the multicriteria decision support systems preference ranking organization method for enrichment evaluation I and II

The environmental impact assessment (EIA) is a real problem of multicriteria decision making (MCDM) where information, as much quantitative as qualitative, coexists. The traditional methods of MCDM developed for the EIA discriminates in favor of quantitative information at the expense of qualitative information, because we are unable to integrate this latter information inside their procedure. In this study, we present two new multicriteria decision fuzzy methods called fuzzy in preference ranking organization method for enrichment evaluation (FPROMETHEE) I and II, which are able to integrate inside their procedure quantiative and qualitative information. This has been performed by applying a new linguistic representation model based on two tuples. These methods, although they have been developed for EIA problems, can be applied to all sorts of decision-making problems, with information of any nature. Therefore, the application of this method to real problems will lead to better results in MCDM. The main interest of our investigation group currently is to develop a set of different multicriteria decision fuzzy methods to be integrated inside a software program that works as a multicriteria decision aid. © 2003 Wiley Periodicals, Inc.
