Abstract

Currently, leading automotive upholstery manufacturers face production delays in the rear seat upholstery of the RSC 40% model, exceeding the company’s standard time and resulting in unmet production targets. Originally 66 pieces per day, customer demand per day is equal to 88 pieces per day. The reliance on manual labor causes inconsistency, low efficiency, and production waste due to unbalanced workloads. This study applies two methods Ranked Positional Weight for line balancing and the ECRS principle for waste reduction to enhance production efficiency. Data collected in July 2023 from the evaluation of production line efficiency with Flexsim program, add from 73.4% to 87.9% and 94%, while daily output rose from 66 pieces to 89 and 95 pieces. The improvement also reduced costs by 218,407.5 baht per year.
