Also,existing limitations in the said unit including production capacity,batch size for ordering raw materials and financial limitation for purchasing raw materials are considered for the model.  the fuzzy reliability of suppliers and contractors has been specified by a fuzzy expert system with no presumption for demand distribution, and  to control and correct all the anticipation deviation from the fact,the rolling horizon technique is used and finally safety stock has been set in such way that the minimum total cost and the customer service level have reached a designed level.
