Interval TOPSIS for Multicriteria Decision Making

In this paper, an interval version of the classical multicriteria TOPSIS method is proposed. In particular, the so-called Bag-Based TOPSIS proposed by Rebai will be considered, and suitably modified to treat with interval number, using the acceptability index suggested by Sengupta. Interval analysis can be a powerful tool to deal with complex decision problems where the values of the criteria for each alternatives can be characterized by uncertainty.
