نمذجة مشكلة التخطيط الإجمالي للإنتاج في حالة الطلب و التكاليف مبهمة : دراسة نظرية و تطبيقية

الملخص EN

In this study, we have modeling the problem of aggregate production planning(APP) in the nationalfirm of iron manufactures non- metallic and useful substances so that its productive management can beable to specify an optimal production plan through which it faces the seasonal demand fluctuations on itsproducts.For this, we have made use of Fuzzy mathematical programming In the case of fuzzy demand andfuzzy costs because of the circumstances surrounding uncertainty, where we have formulated amathematical model is designed to minimize the total cost of production, workers, and storage, using for that the method of Chanas (1983), the mathematical model is solved by using MATLAB and LINGO programs and getting optimal production plan.
