A note on the role of robustness analysis in decision-aiding processes
نویسنده
چکیده
Robustness analysis is an increasingly popular response to the difficulties in setting the parameter values of decision aiding models, for individual or group decisions. This note discusses three possible roles for robustness analysis in a decision aiding process. Considering the difficulties of eliciting values for preference-related parameters, we will argue the potential benefits of using robustness analysis throughout the whole decision process as a tool to guide that process, which is the idea behind tools such as VIP Analysis or IRIS and their extensions for group decision-making.
