An EOQ Model for Deteriorating Items with Time Varying Demand and Costs
研究了一个易腐品的经济订货批量模型，其中需求率、腐败率、持有成本和订货成本均为时间的连续函数，允许缺货且完全积压，推导了最优补货策略和决策规则，并给出了数值算例和敏感性分析。
A generalized EOQ model for deteriorating items is considered here in which the demand rate, deterioration rate, holding cost and ordering cost are all assumed to be continuous functions of time. Shortages are also allowed and are completely backlogged. The planning horizon is finite and the replenishment periods are assumed to be constant. The optimal replenishment policy and the decision rule which minimizes the total system cost are derived. A numerical example is given to illustrate the developed model. Sensitivity analysis is also presented for the given model.
