【摘要】：为研究废旧家电产品回收库存控制问题,构建了回收点、回收中心和回收工厂的三级回收网络。考虑废旧家电产品回收时间和数量的随机性,给出三种回收方式的回收分布;将回收中心的回收量与回收工厂的处理能力相关联,提出了两种不同的库存控制策略;并以一个时间段内回收过程的平均回收费用为控制目标,建立了库存控制模型。通过求解模型得到回收点和回收中心的最优送货时间,及其在一个运作周期的最小平均回收费用,并可以确定回收点、回收中心和回收工厂的库存量。最后,通过案例分析验证了模型的有效性和可行性。
[Abstract]:In order to study the problem of recycling inventory control of used household appliances, a three-level recycling network of recycling point, recycling center and recycling plant is constructed. Considering the randomness of recycling time and quantity of waste household appliances, the distribution of three recovery methods is given, and two different inventory control strategies are put forward by correlating the recovery amount of recycling center with the disposal capacity of recycling plant. Taking the average recovery cost in a period of time as the control target, the inventory control model is established. By solving the model, the optimal delivery time of recovery point and recovery center and the minimum average recovery cost in a single operation cycle can be obtained, and the inventory of recovery point, recovery center and recycling plant can be determined. Finally, the validity and feasibility of the model are verified by a case study.
