IMPROVING WAREHOUSE MANAGEMENT EFFICIENCY: A CASE STUDY OF AN AUTOMOBILE MANUFACTURING FACTORY IN CHONBURI PROVINCE

Abstract

The objectives of this study were 1) to study the problem of storing raw materials in warehouses and 2) to compare results of improving the efficiency of warehouse management in an automobile plant in Chonburi Province. The sample used in the research are 4 employees working in the warehouse, including the warehouse manager, warehouse office staff, raw material Panning and storage staff, and disbursement staff of an automobile production plant in Chonburi Province. From the study and data collection, it was found that the use of fishbone charts to analyze the causes of redundant and inefficient operational procedures was as follows. Problem 1: The inventory data in the system does not match the actual count amount. Problem 2: Deterioration and obsolescence of raw materials were caused by the inability of the staff to disburse the raw materials according to the system (FIFO). Problem 3: The disbursement period is longer than the specified threshold. After the improvement, it is summarized as follows. Problem 1: The performance of warehouse staff decreased by 14.86%. Problem 2: Waste storage decreased by 12.86% to 42,366.67 Baht. Problem 3: After improving the storage area, layout, grouping of raw materials, labeling zones to make the staff procure raw materials faster compared to 3 months, the time for slow disbursement decreased by an average of 10.43 minutes per 1 disbursement from January to March 2024.
