摘要
本文给出了用三次函数近似拟合需求率符合产品寿命周期变化规律的库存模型，得到了这一模型的整体最优解。
Economic Order Quantity (EOQ) inventory model are considered for the situation of steady demand. But putting a new product on the market, demand rate in its whole life cycle rises from zero and reaches a top at some time, and then demand begins to fall, eventually reaching zero.This paper gives an analytic solution of an inventory model for thd whole life cycle fitting approximation of a cubic function.
