回收努力影响下循环物流包装库存策略优化

Optimal Inventory Strategy of Reusable Logistics Packaging Considering Collection Effort

目的 解决循环物流包装放置混乱造成循环物流包装返回率低、循环物流包装运营成本增加的问题。方法 在循环物流包装库存模型中引入回收努力作为决策变量,建立非线性规划模型,分析循环物流包装的最优检查周期、购买周期和最优回收努力水平的决策问题,设计迭代算法进行求解。比较分销商投入回收努力与不投入回收努力情况下系统的总成本和决策变量。结果 包装的最优检查周期为2.78,最优购买周期为4.88,分销商最优努力水平为230.96,系统总成本降低了42%,循环物流包装的检查周期缩短了49%,购买周期缩短了13%。结论 在循环物流包装的应用中,加强对循环物流包装管理流程的培训力度有利于循环物流包装系统更有效的运行。

The work aims to solve the problem of low return rate and increase of operating cost of reusable logistics packaging due to its packaging misplacement. The collection effort was introduced into the reusable logistics packaging inventory model as a decision variable. A nonlinear programming model was established to analyze the decision-making problems on the optimal inspection cycle, purchase cycle and the optimal collection effort level of reusable logistics packaging, and an iterative algorithm was designed to solve the problem. The total cost and decision variables of the system with and without the distributor’s collection efforts. The optimal inspection cycle was 2.78,the optimal purchase cycle was 4.88, and the optimal effort level of distributors was 230.96. The total cost of the system was reduced by 42%, the inspection cycle of reusable logistics packaging was shortened by 49%, and the purchase cycle was shortened by 13%. In the application of reusable logistics packaging, strengthening the training of reusable logistics packaging management process is conducive to the effective operation of reusable logistics packaging system.
