SOLVING A FUZZY TRANSPORTATION PROBLEM BASED ON EXPONENTIAL MEMBERSHIP FUNCTIONS.

In the traditional transportation problem, it is assumed that decision makers are confident about the exact values of transportation costs, supply and demand of the product. When solving a transportation problem with inaccurately determined transportation costs, supply and demand quantities, a fuzzy approach is used. In this paper, a transportation problem based on statistical data is considered. The frequency distributions on the transportation costs and the supply and demand quantities in real-life transportation problems are used as the base for determining the parameters of exponential membership functions. An approach for solving fuzzy transportation problem using exponential fuzzy numbers is proposed. A numerical example is solved to illustrate the described approach [ABSTRACT FROM AUTHOR]
