On the Constructive Role of Multi-Criteria Analysis in Nuclear Emergency Management

In this chapter we argue that multi-criteria analysis, as an iterative process, can be a useful instrument for improving decision-making in complex so-cietal problems. As a possible application, we focus on the management of contaminated milk following an accidental radioactive release to the envi-ronment. We describe a stakeholder process for the development of a multi-criteria decision aid model and we show that the related problem structuring has led to the exploration of some new research topics, in order to gain more insight in the factors that can contribute to a successful coun-termeasure strategy. Such results have on the one hand a clarifying role in a comprehensive multi-criteria analysis and, on the other hand, they high-light practical implications for decision-making, including communication on potential countermeasure strategies both between various stakeholders and with the general public.
