Dealing with conflicting targets by using group decision making within PROMETHEE
This paper presents an approach to applying PROMETHEE for group decision making to support strategic decision making for the implementation of product-service systems (PSS). Such strategic decisions are not only dependent on profit but also on other economic and ecological criteria, i.e. gain or loss of knowhow and chances as well as risks concerning cooperation. Therefore, the application of a multi criteria decision support methodology is necessary, in order to include both, the provider’s and the customer’s perspective. In contrast to the application of PROMETHEE by a single decision maker, the weighting process includes the share of the vote of the different decision makers – as already shown in other approaches – as well as contrary targets of the decision makers for the defined set of criteria.
