Improving the workflow of the packing department to increase productivity with 3D computer simulation modeling, A case study of SJ Screw Thai Co., Ltd.

Abstract

This research focuses on increasing the productivity of the assembly staff of SJ Screw Thai Co., Ltd. by computer simulation modeling. The simulation program is called Flexsim manufacturing, which is generated the prototype model compared with three models to increase productivity. The simulation experiment found that the assembly time per piece was 37.83 seconds for the best scenario that showed a desk design for standing-sitting staff members and adjusting the assembly process to assembling two pieces at a time. The result decreased assembly time per piece by 23.37 seconds. Reduced assembly time by 38.22% per daily production rate that increased from 454 to 500 pieces.
