Abstract

There is a high demand for the diagnostic medical blood analyzer in the global medical device market. The domestic market is in infant stage, but expected to grow very fast. In this study, we attempt to provide several ways for production improvement in order to secure price competitiveness of domestic medical blood analyzer. For this purpose we identify the problems of current production process using ARENA simulation and suggest several alternatives for productivity improvement.. Five steps of TOC (Theory of Constraints) and ARENA simulation are employed to predict productivity of each alternative and to suggest further improvement.

진단 의료 혈액 분석기는 세계 의료기기 시장에서 지속적인 고성장세를 이어가고 있다. 본 연구에서는 국내 혈액분석기가 진단 의료기기 시장에서 가격경쟁력을 높여갈 수 있도록 비용을 절감시키면서 낮은 생산원가를 실현시킬 수 있는 생산성 향상 방안을 마련하는데 중점을 두었다. TOC 제약이론의 집중개선 5단계와 공장자동화 전략을 기반으로 시뮬레이션을 모델링하였으며 단계별로 대안을 제시하고 결과를 예측하여 분석하였다. ARENA 시뮬레이션을 이용하여 현장의 상황을 정확히 모델링하였으며 TOC 제약이론 집중개선 5단계를 도입하여 보다 체계적이고 효과적으로 개선하였다. 제약공정의 능력을 확장하는 단계에서는 적절한 공장자동화를 통하여 생산성을 크게 향상시켰으며 자동화 설비 도입에 따른 경제성 분석을 실시하여 투자대비 효과를 입증하였다.
