Application of the ORESTE method to a nuclear waste management problem

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 management, in which 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 problem an outranking method like ORESTE seems particularly 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 prove that the results are largely independent of the assumed order relation on the criteria.
