| Summary: | An efficient storage and retrieval system helps in reducing the cost of operation of the industry. Demand, warehouse layout, location of items and picking methods are factors that affect to the storage and retrieval system efficiency. The aim of this research is to assess the storage and retrieval system in Bulk Storage Area (BSA) of an apparel accessories industry. The method operators carried out their tasks, the facilities layout and structure were observed and working procedures were examined through interview. The available rack and occupied rack space were measured to determine the storage utilization. Time and motion study were carried out to evaluate efficiency in retrieving operations. The study concluded that average only 22.5% of rack spaces were utilized. The average retrieving efficiency of one item was 72.4% while 75.1% for two items. The highest value added (VA) operation time was untie and weight the items which occupied 31.4% whereas highest non-value added (NVA) time was transportation with 67.2%. The interview and observation also revealed that Standard Operating Procedures (SOPs) were not available for storing and retrieving process. Thus, the SOPs was proposed for storage and retrieval system to increase the system efficiency. Implementation of SOPs for retrieving operation of order with one item showed reduction of VA time by 31.4% while 62.1% for NVA time. The total time was decreased by 42.4%. |
