Abstract
Selection of appropriate machine tools for a manufacturing company, because that effects on product process, is a very important. But by imprecise information, the selection will be complicated. The VIKOR method is one of new methods for solving problems of multiple criteria decision making where its objective is selecting the best alternative based on the closest feasible solution to the ideal solution. In this article will be proposed a fuzzy approach for the VIKOR method where rating alternatives and importance weights of criteria are considered as fuzzy numbers. Also in the proposed method, importance weight of DMs thoughts is considered different. For illustrating the proposed method, a numerical example about machine tools selection has been presented for illustrating the proposed method, where criteria of alternatives evaluation are flexibility, confidence ability and maintainability of machines.
