Abstract


The aim of this research is to study transport system in Darab Siman Omid (cement) manufacturing Company where system optimization is carried out at 3 phases: we have implemented 3 phases of this point for December 2012 through August 2013 .Therefore, 3 phases are explained in the following: At the first phase, with respect to customers’ demand and by application of linear planning, quantity of the needed trucks for any route is identified in certain period of time. At the second phase, it is determined by goal programming model and the number of the existing trucks i.e., how many trucks should be allocated to any route. Moreover, at the second phase, quantity of deficiency or surplus of trucks will be obtained for each route within several periods as well and finally at the third phase, the extra trucks, which have been focused on by this method of allocation in the main base, will be allotted to the routes with respect to the shortages of these facilities obtained from the second phase of this problem. Currently, we compare the suggested system with the existing system. The acquired result from this part signifies that the given company should reduce the number of trucks from this system in order not to be compelled to incur their extra costs or it should meet more demands with this quantity of trucks at its disposal.
