D-Sight

PROMETHEE and GAIA belong to the family of multi-criteria outranking methods. A key aspect of their successful application to real problems relies on the existence of user-friendly software implementing these approaches. Following PROMCALC and DECISION LAB 2000, D-Sight is the third generation of PROMETHEE and GAIA based applications. It offers multiple interactive and visual tools that help the decision maker to better understand and manage his multi-criteria problem. The aim of this paper is to provide a description of D-Sight by presenting its main characteristics. An illustrative case study about the outsourcing of IT infrastructure and application development is detailed.
