线性信用支付下变库存费的变质性物品的EOQ模型

EOQ Modle for Deteriorating Items with Holding Cost Function and Linear Trade Credit

研究了信用支付期为订购周期线性增函数,库存费为库存量的非线性多项式函数的情况下,变质率和需求率均为固定的物品库存模型.讨论了信用支付期为零、小于和大于订购周期3种情况下的库存费用,并进行了近似计算,制定了最优存储策略.

Considering trade credit which is the linear increasing function of ordering cycle and holding cost which is the nonlinear polynomial function, the inventory model for deteriorating items with constant deterioration and demand rate was studied. The inventory cost functions were discussed when the trade credit is zero,shorter and longer than the ordering cycle. Analgorithm of optimal solution of the model is found.
