A methodology for sensitivity analysis in three-criteria problems: A case study in municipal management

Abstract

This paper describes part of an on-going research project studying the issues of the application of Multicriteria Decision Aid Methodologies in real case-studies at the local level of the Portuguese Public Administration. In a first part, it address the complexity of decision situations in municipal management in general and the significance of decision analysis, namely multicriteria evaluation procedures, in conducting decision aid processes in that environment (Section 1). In a second part, a case study is described (Section 2), followed by its discussion in the ‘space of the weights’ in the context of different particular types of possible problem formulations (Section 3). For this purpose, an extension of Triangular Decision Technique is first proposed, followed by the presentation of a new Outranking approach, designated by ‘ Outweigh’ analysis, which will permit the enrichment of the discussion.
