Abstract

This paper proposes Dual DBR(Drum-Buffer-Rope) system for a small-to-medium-sized PCB(Printed Circuit Board) manufacturing line. DBR method of TOC(Theory of Constraints) is an effective system for a small-to-medium-sized company to build production scheduling system. But to apply it to PCB line, it needs more technical consideration because of multiple constraints, looping process line and complex buffer management. This paper proposes an answer of these problems using Dual DBR to build production scheduling system more successfully. And it was confirmed that lead time was reduced more than 20% applying Dual DBR system to a domestic PCB manufacturing line actually.

중소 PCB 제조업체에서는 외부 생산 환경 변화, 복수개의 제약공정, 많은 공정수, 긴 리드타임, 동일공정 반복생산 등의 특징으로 인하여 효과적인 생산 스케쥴 작성에 많은 어려움을 겪고 있다. 최근 TOC 이론에서 제시하고 있는 DBR기법을 PCB 생산라인에 적용하고자 하는 시도는 진행되고 있으나, 제약공정을 1개만 설정하도록 하는 일반적인 DBR로서는 PCB 생산라인의 특성상 충분한 효과를 기대할 수 없는 현실이다. 따라서 본 논문에서는 PCB 생산라인에서 효과적인 생산스케줄링을 수립하기 위하여 TOC의 DBR기법을 발전시킨 복수 DBR기법을 제시하였다. 또, 실제로 국내 중소 PCB 제조업체에 복수 DBR을 적용하여 제조 리드타임을 20%이상 단축함을 확인하였다.
