Abstract

Improving the time and cost efficiency of production systems is one of the important means of building competitive advantage and staying profitable in the ever increasing competitive business environment. Among others, CONWIP (constant work-in-process) and DBR (drum-buffer-rope) methods are widely used in improving production process efficiency. In this study, we have developed simulation models for a real button factory production system. We have tried to improve the efficiency of the production process by implementing these two approaches to our model. According to our results, both CONWIP and DBR production approaches were found to have equivalently better results in reducing the waiting time of the bottleneck process. By applying either of the two production systems, efficiency of the real production process can be significantly improved as the simulated model results demonstrate.

생산시스템의 시간과 비용 효율성을 개선하는 것은 경쟁 우위를 구축하고 경쟁적인 비즈니스 환경에서 수익성을 향상하는 중요한 수단 중 하나이다. 그 중에서도 CONWIP(constant work-in-process)과 DBR(drum-buffer-rope)방법은 생산 공정의 효율을 개선하는 데 널리 사용된다. 이 연구에서는 실제 단추 공장 생산 시스템의 시뮬레이션 모델을 개발했다. 연구 결과에 의하면, CONWIP과 DBR 생산시스템 모두 병목 공정의 대기 시간을 감소시키는 등 실제 생산시스템보다 나은 결과를 나타냈다. 시뮬레이션 모델 결과를 바탕으로 제안된 생산시스템을 적용함으로써, 실제의 제조 공정의 효율을 크게 향상시킬 수 있을 것으로 기대된다.
