摘　　要：作为电商仓库作业中耗时最长、成本最高的环节,订单拣选的作业效率一直是仓库管理中的关键问题。文章针对拣选策略选择问题,选择Perfect Pick系统的电商仓库作为背景,对单个拣选台进行研究,提出订单分批和订单排序两种拣选策略并进行对比分析;以货箱搬运次数最少为目标,分别构建订单分批与订单排序两种拣选策略的整数规划模型,并设计贪婪算法进行求解。通过数值实验验证,订单排序策略在所有订单规模中均优于订单分批策略,根据仓库的订单规模,合理设置拣选台最大容量并选择合理的拣选策略,能够更好地提高拣选效率、优化仓库作业环节。Order picking is the longest and the most expensive part in the e-commerce warehouse operation,and its operation efficiency has always been a key issue in the warehouse.Addressing the selection of picking strategies,taking the e-commerce warehouse equipped with the Perfect Pick system as the background,this paper conducts a research on a single picking platform,provides two picking strategies,including order batching and order sequencing,and compares and analyzes them.In order to minimize the number of container handling,integer programming models of order batching and order sequencing are constructed respectively,and the greedy algorithm is designed to solve them.Through the numerical experiment,it is verified that the order sequencing strategy is superior to the order batching strategy in all order sizes.Setting the maximum capacity of the picking table reasonably according to the order size of the warehouse and choosing a reasonable picking strategy can better improve the picking efficiency and optimize the warehouse operation.
