Abstract

A sequential zone picking system is a warehouse strategy that divides the order picking process into distinct zones, where items for specific customer orders are retrieved sequentially across these zones. Warehouse operators have made substantial efforts to develop sequencing algorithms that reduce blocking delays and picker idle time, thereby shortening the makespan of the processing window. Recently, the dual-lane configuration of the conveyor system, which facilitates the transportation of picking orders between zones, has proven to be an effective solution for addressing inefficiencies in sequential zone picking systems. This study aims to evaluate the performance of the dual-lane configuration with the simple first-come-first-served batch sequencing rule, in comparison to the single-lane conveyor configuration employing various effective batch sequencing algorithms. The simulation experimental design and results assess these operational methods’ performance by examining both the picking completion time and the completion time of the entire order picking and packing process under various conditions.
