缺货情形下轴辐式库存的纵横向协作调拨

doi:10.12005/orms.2021.0322

摘要/Abstract

摘要： 电子商务发展要求缩短供需端距离,便于提高供应链柔性运作水平,以更好的响应市场需求,这使得仓配环节的纵横向库存协作调拨面临严峻挑战。为此,本文针对零售行业的轴辐式二级库存系统,考虑可用库存及调拨能力限制,以缺货情形下的额外履约成本及销量损失最小化为优化目标,构建纵向及横向综合库存调拨模型,优化每日库存调拨方案。在此基础上,利用改进的三层编码形式的遗传算法对模型进行求解,并通过算例验证了模型及算法的有效性。

Abstract: E-commerce development requires shortening the distance between supply and demand ends, and is convenient for improving the flexible operation level of supply chain, so as to better respond to market demand, which is face with severe challenges for the vertical and horizontal cooperative allocation in warehousing and distribution. Therefore, this paper studies the optimization of the vertical and horizontal cooperative allocation in retail industry.Based on the secondary hub-and-spoke inventory system, considering the limitation of available inventory and allocation capacity, the vertical and horizontal comprehensive inventory allocation model is built to optimize the daily inventory allocation plan, by taking the minimum of additional performance cost and sales loss in the case of shortage as the optimization objective. On this basis, the improved three-layer genetic algorithm is used to solve the model, and the effectiveness of the model and the algorithm is verified by an example.

Key words: horizontal allocation, inventory allocation, hub-and-spoke network, genetic algorithm
