Application of the ORESTE method to a nuclear waste management problem

Abstract Many multicriteria analysis methods require some detailed information concerning the different criteria: weights; order relation; preference functions; etc. However in many real cases, it is quite difficult to provide this information. The following paper presents a decision problem on nuclear waste managemnt, in while little information is available on the multiple criteria, representing each the point of view of a different actor: electricity producer, consumer, public body. For this type of decision problems, an outranking method like ORESTE seems particulaly well adapted because its only request in a preorder of the criteria. It has been applied and a sensitivity analysis is performed in order to provide that the results are largely independent of the assumed order relation on the criteria.
