Heuristic algorithm for multi-index fixed charge fuzzy transportation problem

Author:W.Ritha and J.Merlin Vinotha

Abstract:
This paper develops a heuristic algorithm for the multi-index fixed charge transportation problem. The efficiency of this algorithm for solving the multi-index fixed charge transportation problem has been proved by comparing the results obtained by using this algorithm with the existing exact method of solving multi-index fixed charge transportation problem. Further the proposed algorithm is extended to multi-index fixed charge fuzzy transportation problem in which all the parameters are considered as trapezoidal fuzzy numbers. A numerical example is presented to illustrate the proposed method.
