Multiple criteria decision aid for selecting the best product end of life scenario

There exist several scenarios for treating an end of life (EOL) product and each scenario has different environmental, social and economic consequences. An EOL scenario can be better than another with respect to one criterion but worse with respect to another criterion. To compare EOL scenarios with respect to conflicting criteria, a multiple criteria decision aid (MCDA) method should be used. In this paper, we present the MCDA approach developed in the project AEOLOS (An End-of-Life of Product Systems) for supporting users in the selection of the best scenario for treating an EOL product on the basis of their preferences and the performances of the EOL scenarios with respect to relevant criteria.
