A Hierarchical Production Planning Framework for Part Families

tendency to optimization in last decades has resulted in creating multi product manufacturing systems. Production planning in such systems is difficult because optimal production volume that is calculated must be consistent with limitation of production system in this article we seek to create production planning framework in in order to produce different parts families. the rpoposed production planning has heuristic approach and renders a procedure to determine production priority of different part families based on safety stock and safety lead -time.
