Abstract:
This research is a case study to improve and enhance the efficiency of workflow of an automotive warehouse. From the case study of the warehouse management method, it shows that the volume of raw materials do not correspond the scope of work. As a result, the warehouse has insufficient storage space. Raw materials are forced to be stored outside the warehouse area not associate to each others and without identifying the storage location in a proper manner, which affects the work efficiency of the warehouse personnel. Warehouse personnel are required to spent more time to locate, gather, and deliver the raw materials. On some occasions, warehouse personnel are unable to gather the required raw materials within a day and have to continue withdrawing raw materials the next following day, which has an overall effect of the warehouse management performance. The researcher has studied and analyzed the cause of the problem by using a flowchart diagram to find a solution to resolve this problem by reorganizing the warehouse plan. New storage racks and Identification signs for raw materials have been purchased as well as setting of raw material withdrawal cycles for the production line. Raw materials have been grouped using ABC analysis by evaluating the amount of raw materials withdrawn from the past 3 month. It is suggested to reduce the amount of stocking raw materials and to increase the frequency of delivery of raw from raw material supplier. The result of this research will help to improve warehouse operations by gaining back sufficient storage space for raw materials, reduce the amount of workforce to locate the raw materials from 3 to 2 people which has an effect on reduction of cost by THB 184,140 per year. In addition it helps to increase the capability of warehouse management and resources for the benefit of the organization.
