Abstract
This research aims to analyze supply chain issues and develop solutions to improve supply chain efficiency based on a battery import business case study by collecting information on activities occuring in the warehouse sector, recharging and product inspection before shipping to the distribution center. A current value stream mapping is used to prepare a current supply chain performance study and assessment, fishbone diagrams are used to identify issues and causes that affect the performance, and a future value stream mapping is used to determine guidelines for supply chain efficiency improvement. The study discovered that four variables, including people equipment, locations, and processes, are the main drivers of difficulties influencing supply chain efficiency. The following are the solutions: 1) Creating organizational awareness and responsibility 2) Relocating the working area to the same location 3) Making a PM planning for warehouse building 4) Using a Cooling Tunnel 5) Using WMS and ERP in the operational processes. This solution can improve the performance by reducing operational activities from 29 to 17 activities, reducing work hours from 11,058.51 to 874.76 minutes, reducing moving distance from 34,805.00 to 1,012.00 meters increasing the workload from 315 to 504 batteries/day (60.00%), and reducing costs from 35.56 to 27.59 baht/battery (22.41%).
