Determination of the best alternative position for the storage location product assignment problem by multiple criteria decision making methods

The use of an efficient warehouse especially should be taken into consideration, in terms of distance, area of use, and minimization of costs arising therefrom. Therefore, for the storage location assignment problem, the best storage assigement policy must be applied to minimize the total transport time or distance during the storage process and to reduce the space needed. Therefore; the importance of this study, taking into account more than one criterion with multi-criteria decision making method obtain the compromise solution value for each product and the optimal location for class-based storage asignment in a warehouse according to these values. In this study, it is aimed to determine the best alternative location by considering multiple criteria such as transportation distance, usage area, product demand, sensitivity, profitability and minimization of the cost arising thesefrom in a storage area. It is aimed to determine the best alternative policy to be applied to a mathematical model that minimizes the transportation time or cost for storage asignment within the warehouse area by using Multi-Criteria Decision Making (MCDM) methods. For optimal location, mathematical model proposed by Muppani and Adil are taken as reference and this model consists of transportation distance, area and cost items arising from them. According to the determined criteria, concordant solution values for each product were obtained by VIKOR method and input into class formation and allocation model. Class formation and allocation model based MCDM was solved with GAMS / BARON software. The data used for the solution are randomly generated. The results showed that the products can be assigned to the warehouse by taking into consideration multiple criteria according to the decision maker's preference.
