Simulation Study of a Multi-Level Shuttle System with In-rack Picking Stations

: This paper addresses the evolving warehouse automation scenario in supply chain management, focusing on the design and simulation of a multi-level shuttle system. Unlike existing studies, the proposed system integrates picking stations within the storage rack, optimising space and improving picking efficiency. A discrete event simulation is proposed to model the system design and operation. The model also integrates different strategies for selecting items and serving picking stations. The paper provides insights into efficient warehouse processes from both a theoretical and practical point of view by presenting a structural model, simulation results and implications.
