The Impact of Object-Oriented Order Picking System on Performance in a Supply Chain

摘要

Simulation has been proven one of the fundamental methodologies in operations research-related fields. The simulation created by an object-oriented program has the advantages of hierarchical structures, inheritance, polymorphism, and the re-use of objects. This paper uses eM-plant software for object-oriented, which is based on the minimum overall traveling distance as the optimum performance index, the cross aisle quantity, warehouse layout, storage assignment, picking route planning, and picking density in the warehouse system. This paper aims to improve the performance of order picking system in a warehouse through an object-oriented simulation study. Data are obtained from a real case. This study examines several storage assignment policies and several sensitivity analyses. Finally, the results provide managers as a reference in the warehouse planning or warehouse design improvement in the future.
