This project deals with a case study of SALBP in power transformer manufacturing. Some workstations in assembly line experienced bottlenecks, while the others suffered with high idle time. Therefore, four heuristic methods are chosen in order to provide solutions for minimizing number of workstations and improve the bottlenecks simultaneously. In this study, LCR, RPW and LPT are successfully minimized number of workstation from 19 to 16 workstations. Consequently, these solutions affect the layout. On the contrary, SPT able to improve the bottleneck by reducing number of workstations from 19 to 17 without affect the line layout. Therefore, this has created an option for engineer to decide which decision should be implement to the assembly line due to enhance the line efficiency.
