Abstract: The objective of this research is to present an application model to plan the operations and to control the orders (the case study: profile door and window manufacturing (upvc)). The method applied in this paper is the field study. The measurement tools have been analyzed via investigating and analyzing the existing evidences, observations and interviews, and also taking use of the scientific models associating with the inventory control. This research has been in a way that primarily the mostly used raw materials in the year 2009 are determined and 6 items of the raw materials which included almost 94% of the warehouse inventory were chosen as the sample via ABC classification. Then, using EOQ formula the optimum amount of the order and using the ROP formula the reorder point and the precautious storage (Ss) have been calculated in the confidence level of 95%. In the next step the secondary optimization was performed on the basis of the order period system and finally the approach concerning the suggested model has been presented in order to plan and control the inventory of the items for the future period. The total results achieved imply that doing optimization, the total cost reduces considerably, and the possibility of not facing the deficiency of raw materials has an increase of 15%. Also the order status turned from the current system to the optimum system
