In recent years, the market has been competitive and the customer behavior has been changed. In order to improve the efficiency of workflow and to meet orders, the warehouses play an important role in supply chains. Thus many companies start to install Automated Storage/Retrieval Systems (AS/RS) to increase the efficiency and reduce the cost of order picking. Therefore, this study purposes two kinds of storage planning with combining product relevance, Cube-Per-Order Index (COI) rules and storage assignments which can effectively reduce the picking cost and travel distance. This study equals the workload of all zones with storage assignments of product relation and balancing workload. The method can reduce idle time of machine operation. On the other hand, it can reduce the overall travel distance to achieve the purpose of improving the picking efficiency. Finally, the results show that there is no significant difference between two kinds of storage method and COI rule storage, but two kinds of storage method can balance the workloads. |
