การเพิ่มประสิทธิภาพกระบวนผลิตอุปกรณ์เครื่องใช้ไฟฟ้าโดยวิธีการจัดสมดุลสายการผลิต

This research aims to increasing efficiency in production and eliminate the problem of insufficient production capacity with respect to customer demand for electrical appliance factory by applying the line balancing method. Thus the study then developed two problem-solving approaches. The first approach is a method by which a firm applies the line balancing concept and ECRS technique (Eliminate Combine Rearrange and Simplify). On the contrary the second approach is required an investment in testing machine with value of 1000000 baht in order to support sufficient production capacity to meet customer demand. Also ECRS method is used to accomplish this process. Based on the results the first approach provided the production line efficiency improvement representing of 82.59% and reduced the labor cost of 277220 baht per year. However the loss of commercial opportunity has remained the same of 6336000 baht per year. Accordingly the second approach demonstrated of 92.11% of the production line efficiency improvement and the labor cost reduction valued of 277220 baht per year. As we expected the second approach satisfied production efficiency by eliminating the loss of commercial opportunity with value of 6336000 baht per year delivering a return of investment within two months.
