Abstract
The aim of this study is to improve plant layout and manufacturing process for more ordering of LED bulb light factory by using ECRS technique for eliminating the non-value-added activities, such as the bottleneck process, time delay, unnecessary motion and the long-range material handling problem. The study started with the analysis of demand and LED bulb light factory problems for the systematic layout planning (SLP). Then, collected data of each workstation such as the cycle time and takt time for the assembly line balancing were performed. After that, this research had designed the process, solving the problem by applying industrial engineering tools, and engineering economic analysis. The results of plant layout improvement showed that, the range of material handling is decreased by 622 second or 40.17 %, and the cycle time of material handling is decreased 620 second or 49.60 %. From the improvement of production process, there found that can increase average productivity by about 717 pieces/month for 1,683 pieces/month. The production capacity is increased to 2,400 pieces/month for 1,600 pieces/month. The investment cost of 3,892,240 baht and the return of investment rate is 41.63 % with 2.4 months payback period.
Keywords: productivity; line balancing; systematic layout planning
