Abstract The disassembly economic order quantity problem is to determine the quantities of a product to be disassembled at different times over an infinite planning horizon by considering ordering, operation, and inventory costs. The demands for the components are independent, which can lead to accumulations of unnecessary inventories over time. This article proposes the models which integrate price-sensitive demands and disposal decisions in disassembly economic order quantity problems to maximize the profit of disassembly systems without inventory accumulations. Three models are developed and analyzed to obtain solution approaches that give prices, the replenishment cycle time (or, equivalently, the order quantity), and the disposal quantity. The inventory policy integrating both pricing and disposal decisions allows higher profits to be achieved. A numerical experiment shows its efficiency and highlights its potential implementation in practical cases.

拆解具有价格敏感需求的 EOQ 模型

摘要 拆解经济订货量问题是在一个无限的计划范围内,考虑订货、操作和库存成本,确定一个产品在不同时间需要拆解的数量。对组件的需求是独立的,随着时间的推移,这可能导致不必要的库存积累。本文提出了在拆卸经济订单数量问题中整合价格敏感需求和处置决策的模型,以在没有库存积累的情况下最大化拆卸系统的利润。开发和分析了三个模型以获得给出价格、补货周期时间(或等效地,订单数量)和处置数量的解决方案方法。整合定价和处置决策的库存政策可以实现更高的利润。数值实验显示了其效率,并突出了其在实际案例中的潜在实现。
