제조실행시스템 도입효과 분석을 위한 프로세스모델링 기반 수행도 분석 방법론에 관한 연구

The global economic crisis is intensifying the competition among manufacturing companies. To meet such circumstances, they attempt to follow business trends by managing production and information efficiency. Therefore, many companies introduce a manufacturing execution system (MES) to increase their productivity. The MES is a manufacturing information system to deliver and share information which optimizes the production from order launch to finished goods. To achieve the desired effect by embodying MES, process modeling is particularly important step to design manufacturing data architecture and MES functions. Furthermore, the comparative analysis before and after introducing MES allow to decrease failure risk of introduction of MES. Therefore, we introduce manufacturing process modeling methodology referred to as Part-flow based Manufacturing Process Modeling (PMPM), aims to analyze and define the discrete manufacturing process including collaborative works. We apply the PMPM to a performance analysis by converting to Petri net model for pre-analysis of effects of MES using Reachability tree. PMPM based performance analysis methodology allows companies to measure on the performance changes of processes between before and after introducing MES. We expect that this research can support decision makers to establish the strategy of design MES in early stage of the MES introduction progress.
