Cost Varying Interval Transportation Problem under Two Vehicle

In this paper we represent a two-vehicle cost vary- ing interval transportation model (tvcvitm). to determine the cost interval of cost parameters of interval transportation problem(itp) we use two vehicle cost varying tp. in this model the transportation cost varies due to capacity of vehicles as well as amount of transport quantity. at first we propose an algorithm to determine limits of the interval of unit transportation cost. this is an uncertain multi-level programming model. then formulate corresponding multi-objective crisp model. to solve this, apply fuzzy programming technique. a numerical example is presented to illustrate the tvcvitm.
