Solving Problems in SSEH: The Use of Decision Support Tools

In this chapter, we propose an introduction to the multicriteria approaches as well as an approach that can allow the Analyst to choose the appropriate multicriteria method during expertise problems. The status of an expert is not absolute: it is dependent upon situational context, DM needs, and other background considerations. In what follows, we will use the term “Study of risk” (SR) to designate the large category of problems that Analysts/Experts have to handle. SR represents problems that are set by the DM or stakeholders and reframed by the Analyst. For this purpose, we will first review the basic concepts used in multicriteria decision aiding approaches. We will then present the main principles of the multicriteria decision aiding methods. Finally, we propose a typology in four SR categories and a choice of multicriteria decision aiding methods that are adapted to each category.
