نموذج البرمجة الرياضية بالأهداف ذات الأولوية كأداة فعالة في التخطيط الإجمالي للإنتاج : دراسة حالة المؤسسة الوطنية للصناعات المعدنية غير الحديدية و المواد النافعة

الملخص EN

This study presents the mathematical formulation of problem the Aggregate production planning (APP), in the National firm of iron manufactures non- metallic and useful substances, So that its Decision Maker of production management in the firm can be able to specify an optimal production plan through which it faces the seasonal demand fluctuations on its products.

For this, we use Lexicographique goal programming(LGP) Which takes into account the importance of the target in order of priority .

The proposed mathematical formulation attempts to minimize total production and work force costs, carrying inventory costs and rates of changes in Work force.

we have used compromise programming way zeleny(1981) in designating them, so that in the end, the mathematical sample is solved by using LINGO program and getting optimal production plan
