Development of a part rack assignment and placement sequencing method for efficient PCB assembly

효율적인 PCB 조립을 위한 부품 랙 배정 및 삽입순서 결정 방법의 개발

In this study, a heuristic for surface mounters is developed to find an efficient sequence on PCB and rack assignment by component grouping. As setting up 4 reels in a group, the distance of rack moving can be minimized. And then, a generalized model for N reels in a group is developed. It is found that the performance of this heuristic is better than other heuristics found in the literature. Throughout the simulation study, the suggested heuristic is performed about 8.2 ∼ 12% better than other heuristics.
