파레토 기법을 활용한 실시간 서열시스템에 관한 연구

Abstract

For zero inventory and mixed assembly production , JIT (Just In Time) production system in Toyota and JIS (Just-In-Sequence) production system in Hyundai motor co. have been proposed. Even though the production systems are popular in automobile production area, many subcontract companies producing part-modules for final production at a parent company suffers from excessive or shortage amount of inventory due to the time gap of production and delivery to the parent company. In this study, we propose an efficient realtime assembly sequence system applying a well-known Pareto method using Paint-In information in painting process and daily production planning information. Based on this system, a production line can estimate the shortage amount of UPH(Units Per Hour) at production line and recovers the amount before operating assembly production in the line. The proposed system provides an efficiency on productivity compared with the previous system.
