Multicriteria decision analisys to lead about messes problems: an illustrated case

Abstract

This paper shows the use of two approaches in Operations Research - Soft Systems Methodology (SSM) and Constructivist MultiCriteria Decision Aid (MCDA-C) - into one decision aid model (SSM/MCDA-C) to lead about messes problems. In order to this, describes the approaches which give theoretical framework support to the proposal, MCDA-C and SSM, as well as presenting the SSM/MCDA-C model. There is also a demonstration of its practical application. Finally, presents the general theoretical and practical considerations and recommendations with regard to the integrated problem structuring model proposed.
