Ranking of suppliers with MCDA technique and probabilistic criteria

Supplier ranking problem is a widely discussed topic in the area of Supply Chain Management. This paper proposes to use a Multi-Criteria Decision Analysis technique, TOPSIS for ranking suppliers. Modified Triangular Fuzzy TOPSIS is proposed for ranking the suppliers. However the novelty of this paper lies in the treatment of the criteria as considered in this paper. Some of the criteria are considered to be essential and thus are used always. The uses of the remaining criteria are probabilistic since they may or may not be used depending on the situation and the set of alternative suppliers considered. A numerical problem shows the successful application of such idea and shows that such idea can be implemented.
