the current study set to extend a new vikor method as a compromise ranking approach to solve multiple criteria decision-making (mcdm) problems through intuitionistic fuzzy analysis. using compromise method in mcdm problems contributes to the selection of an alternative as close as possible to the positive ideal solution and far away from the negative ideal solution, concurrently. using atanasso...

Multi-criteria decision making (MCDM) is one of the most common activities in human society. It consists of selecting the optimal one from a set of available alternatives with respect to the predefined criteria or attributes. In this paper, a hybrid decision making approach integrating Analytical hierarchical process (AHP) operators into VIKOR is proposed for tackling multi criteria problems wi...
