摘要: 近年来随着电子商务的快速发展,分拣订单呈现批量小、品种多、配送周期短、精度要求高等特征,这对分拣作业提出了更高的要求。为了缩短分拣时间、降低分拣成本、提高分拣效率,物流企业开始逐步使用双层分拣设备。本文采用了"成组分拣"方法以提升托盘利用率,"成组分拣"是指一种将分散的单件包裹按一定的规则组合在一起,成为一个规格化、标准化的大分拣单元进行分拣的方法。根据"成组分拣"的定义,本文研究了一个考虑成组分拣的双层分拣设备目的地指派问题,并设计了一种高效的变邻域禁忌搜索算法,该算法能在较短时间内对该问题进行求解,得到一个满意解。实验结果表明,采用"成组分拣"方法与考虑目的地指派问题可有效提高分拣设备的分拣效率。

Abstract: In recent years, with the rapid development of e-commerce, sorting orders are characterized by small batches, multiple varieties, short delivery cycles, and high precision requirements, which imposes higher requirements on sorting operations. For the sake of shortening sorting time, reducing sorting costs, and improving the sorting efficiency, logistics enterprises have gradually used double-layer sorting equipment. In this paper, the "component-sorting" is used to improve the utilization rate of pallets. "Component-sorting" refers to the method of sorting scattered single-piece packages according to certain rules and becoming a standardized large sorting unit. According to the definition of "component-sorting", the problem of destination assignment for a double-layer sorting equipment considering the component-sorting is studied and an efficient variable neighbor tabu search algorithm is designed that can solve the problem within a short time. The experimental results show that the efficiency of sorting equipment can be effectively improved by adopting the "component-sorting" and considering destination assignment problem.

Key words: double-layer sorting equipment, component-sorting, destination assignment problem, variable neighbor tabu search algorithm
