中文摘要:

      目的 构建英式拍卖模型，以待指派商品品项(SKU)群的最低周转率为媒介，通过逐步提升最低周转率来实现待指派SKU与待指派区域货位数量的匹配。方法 针对移动机器人拣货系统(RMFS)中的货位指派，提出基于英式拍卖机制的货位指派方法，提升仓库拣货效率。结果 与随机指派相比，在不同仓库规模、订单规模、订单偏度的RMFS中采用英式拍卖货位指派机制，机器人行走路程下降比率在大型仓库中达30.17%，中型仓库的下降比率为27.31%，小型仓库的下降比率为24.13%。结论 采用英式拍卖机制在RFMS中进行货位指派可大幅度提高工作效率。

英文摘要:

      The work aims to construct a British auction model to match the number of Stock Keeping Unit (SKU) to be assigned with the number of storage locations in the area to be assigned by gradually increasing the minimum turnover rate of the SKU group to be assigned as a medium. The storage location assignment method based on British auction was proposed to improve the picking efficiency in the warehouse for the storage location assignment in Robotic Mobile Fulfillment System (RMFS). Compared with the random assignment model, when the storage location assignment based on British auction was adopted in RMFS with different warehouse scales, order sizes, and order biases, the travel distance reduction rate of robot reached 30.17% in large warehouses, 27.31% in medium-sized warehouses, and 24.13% in small warehouses. The use of the British auction mechanism in RFMS for storage location assignment can significantly improve efficiency.
