基于EPR的制造商双源库存控制

探讨了生产者责任延伸制度及其与闭环供应链的关系.在分析了闭环供应链下的库存特点后,研究了一种单修复期、多生产期的库存模型.在假设回收数量受到回收价格的控制且当回收价格确定时,不同周期的回收量相等,回收来的旧产品可通过修复方式得到新产品,修复完成后与新产品无差别的条件下,以单周期系统总费用最低为目标函数,能够求解出最佳的单次生产批量和最佳的产品回收价格,为企业决策提供依据.

Double Source Stock Control for a Manufacturer Based on EPR

The relationship between the extended producer responsibility system and the closed-loop supply chain is discussed. The inventory characteristics under the closed-loop supply chain are analyzed and a inventory model for a single repair period, many production period is proposed. On condition that the number of recovery is controlled by the recycling price and is equal in different cycles, the recovered products can be sold as new, an economic production quantity and recycling price can be solved to make the total cost of a single cycle lowest, and the best single production volume and best product recovery price can be solved, which provides a basis for business decisions.
