Determining the Combination of the Production in the Several Lines of Bottleneck by Using Fuzzy Vikor Method

One of the most important decisions that must be made in production systems is determining the product mix. That means which and how much of the product should be made from it in order to increase the final output of the system. Often, in previously existing algorithms, all problem parameters are assumed to be certain and decision-making used to be carried out. The situation studied in this paper is that all the production parameters are in the form of triangular fuzzy numbers. Those production parameters include weekly demand, selling price, cost of raw materials, processing time of products and the available capacity of resources. In the proposed algorithm, considering the multi-bottleneck, with the help of fuzzy Vikor, the prioritization of production is calculated. Finally in order to explain the aforementioned method, a numerical example has been discussed.
