Optimizing Products Transportation in Esfahan Steel Company via Fuzzy Linear Programmig and Enhancement of Warehouse System

Optimizing products transportation is one of the main topics in manufacturing. In large-scaled industries that production does not stopped through day, transportationproblem is significantly noticed to reduce the cost to minimum. On the other hand, the warehouses have such an important rolein transportation planning that any damage or problems in warehouses lead to low productivity of the transportation system. In this paper, evaluating the various conditions of productionand also products transportation, a mathematical model is presented for transportation system in Esfahan Steel Company(ESCo). Then, defining a fuzzy coefficient for the objective function, linear programming strategy is adopted to solve theproblem in various conditions. Such solution gives the optimumnumber of wagons for transporting products from the rolling mill workshops to warehouses. As a practical problem, theinteraction between the trucks loading and wagons unloading in warehouses is analyzed and some suggestions are presented to overcome the problem
