A fuzzy multicriteria group decision making model for performance evaluation of green logistics projects

Evaluating the performance of green logistics project alternatives is challenging due to the presence of numerous decision makers, the multi-dimensional nature of the evaluation process, and the existence of subjectiveness and imprecision in the decision making process. To effectively deal with this kind of decision making problems, this paper presents a fuzzy multicriteria group decision making model for evaluating the performance of green logistics projects in an organization. Interval-valued intuitionistic fuzzy numbers are used to model the subjectiveness and imprecision of the decision making process. An effective algorithm is developed for the performance evaluation process. An example is presented for demonstrating the applicability of the model for dealing with real world green logistics project performance evaluation problems.
