摘　　要：研究了两种仓储能力约束情形下两易逝品联合采购动态批量决策问题。易逝品的特征是库存损失率及库存持有成本依赖于产品库存持有时间,在需求损失(缺货)的情况下将构建的收益最大化模型转化为成本最小化模型,成本最小化模型中包含联合启动成本,两产品单独启动成本、变动采购成本、库存持有成本和缺货成本,分析得出了最优解的结构特性,在此基础上,设计动态规划算法求解问题。同时分析了无投机性成本结构的特殊情形,设计了前向算法求解问题。The paper analyzes the two-product dynamic lot-size problem with perishable inventory and joint ordering under two cases of inventory bounds.The stocks’ deterioration rates and inventory holding costs in every period depend on the age of the stock.We transform the revenue maximization function into cost minimization function,which include joint setup costs,individual setup costs,ordering costs,inventory holding costs and stockout costs.We obtain some structural properties of the optimal solution for a T-period problem and use them to develop a dynamic programming algorithm.Finally,we also consider the case with no speculative motive in holding inventory and stockout.
