储位分配策略直接影响仓储货品的拣选效率与仓库绩效。传统基于物料周转率(COI)的储位分配方法将出入库频率高的货物存储于距离出入口近的储位上,在多巷道分布的仓库当中,这可能导致部分巷道作业拥堵和事故发生率高等。为提升仓储货品拣选效率和减少巷道作业不平衡带来的负面影响,本研究将基于COI储位分配方法与巷道作业平衡改进策略相结合,通过定性解析与模型分析,提出绝对分巷道存储模型和相对平均与最大值控制模型两种储位分配改进方法。通过实例数据分析,两种新方案对行走距离增加值可控制于千分之一以内,而新最优可行解对完善仓储策略和进一步提升仓储企业效率有着重要作用。
儲位分配策略直接影響倉儲貨品的揀選效率與倉庫績效。傳統基于物料週轉率(COI)的儲位分配方法將齣入庫頻率高的貨物存儲于距離齣入口近的儲位上,在多巷道分佈的倉庫噹中,這可能導緻部分巷道作業擁堵和事故髮生率高等。為提升倉儲貨品揀選效率和減少巷道作業不平衡帶來的負麵影響,本研究將基于COI儲位分配方法與巷道作業平衡改進策略相結閤,通過定性解析與模型分析,提齣絕對分巷道存儲模型和相對平均與最大值控製模型兩種儲位分配改進方法。通過實例數據分析,兩種新方案對行走距離增加值可控製于韆分之一以內,而新最優可行解對完善倉儲策略和進一步提升倉儲企業效率有著重要作用。

Optimal storage assignment policies are essential for warehouses. The COI-based storage policy concerns with picking productivity, and so products in small batches but with frequent orders would be stored close to the exit of the warehouse. However, the workload imbalance among different aisles reduces the picking productivity in warehouses. Therefore, two advanced COI-based storage policies are advocated, with the aim of reducing workload imbalance among aisles. The problem is formulated by integer programming models with new constraints introduced. The problem is analyzed with real data and results indicate that satisfactory solutions are obtained, as in similar traveling distance, the advanced COI-based storage policies are more effective to reduce workload imbalance.
