Abstract

The e-commerce industry has driven logistics centers to process massive and time sensitive orders more efficiently and effectively. However, the high land and construction costs have forced the warehouse to adopt a narrow channel layout to increase its capacity, which in turn has caused congestion and further reduced its operational efficiency. Therefore, how to carry out optimization of order batching and picking paths in narrow channels to avoid channel congestion and pursue a lowest total cost has become the problem that this article aims to solve. This article develops a Markov decision process model to address the online order multi-period picking planning optimization challenge, and proposes the Genetic Algorithm-Ratliff Rosenthal-Time Weighted Similarity (GA-RR-MTWS) algorithm which innovatively integrates congestion considerations into the optimization process. A myopic cost function approximation strategy is introduced aiming at minimizing the total cost of a whole working day. Comparative experimental analysis demonstrates the modified cost function GA-RR-MTWS's superior performance in reducing total picking cost and congestion, particularly in complex, multi-aisle environments with multiple pickers. The method's ability to manage congestion and optimize routing significantly improves overall warehouse efficiency.
考虑拥塞的窄通道拣货系统中分批和路由的动态集成优化
电子商务行业推动物流中心更高效地处理大量和时间敏感的订单。然而,高昂的土地和建设成本迫使仓库采用窄通道布局来增加容量,这反过来又造成了拥堵,进一步降低了运营效率。因此,如何在狭窄的通道中对订单批处理和拣选路径进行优化,避免通道拥塞,追求总成本最低,成为本文要解决的问题。本文建立了马尔可夫决策过程模型,解决了在线订单多周期拣选规划优化问题,并提出了遗传算法- ratliff rosenthal -时间加权相似度(GA-RR-MTWS)算法,该算法创新性地将拥塞因素纳入优化过程。提出了一种近视眼成本函数逼近策略,以最小化整个工作日的总成本为目标。对比实验分析表明,改进的成本函数GA-RR-MTWS在降低总拣货成本和拥堵方面具有卓越的性能,特别是在具有多个拣货器的复杂多通道环境中。该方法管理拥塞和优化路线的能力显著提高了整体仓库效率。
