Abstract


Many methods have been discussed earlier for solving fuzzy transportation problem, where the cost coefficients, supply and demand quantities are considered in the form of trapezoidal fuzzy numbers. In this paper we have introduced a method for ranking of the trapezoidal fuzzy numbers with new method to find an optimum solution for fuzzy transportation problem. First, we transform the fuzzy quantities into crisp quantities by using our new method, then obtain an initial basic feasible solution and finally find an optimum solution. This is illustrated with a numerical example. The method is very easy to apply and economical.


Keywords
