| 摘 要： | 基于需求和采购价格均为时变的EOQ模型,进一步考虑呈Weibull分布的变质对易变质物品库存管理的影响,建立了相应的EOQ模型,并对该模型进行仿真计算和主要参数的灵敏度分析.结果表明,该模型存在最优解且各主要参数对最优库存控制有不同程度的影响.

| Abstract: | For deterioration items,the deterioration rate can be described by Weibull distribution.Basing on this assumption,a new economic order quantity(EOQ) model with time-varying demands and purchase prices is developed to analyze the effect of deteriorating items on inventory management.With this model,numerical analysis and parameter sensitivity analysis are done.It shows that an optimal solution for this problem exists and different parameters have different effect on the optimal inventory control policy. |

| Keywords: | deterioration items time-varying demand time-varying purchase price Weibull distribution EOQ model |
