Mathematical model o | in this paper a transportation problem is considered in fuzzy environment in supply and demand constraints to minimize the total cost of transportation. The transportation model is actually a class of the linear programming models discussed in quantitative module b as it is for linear programming, software is available to solve transporta-tion problems to fully use such programs, though, you need to understand the assumptions that underlie the model. We then present our mathematical model in section 4, as well as our method for constructing the time–space graph and a two-step solution approach for solving our integer programming (ip) model we provide computational results in section 5, showing that our model not only provides useful information about itt, but also that it can be.
