Development of Manufacturing Support System for SME under Disruption Risk

This study proposes an idea of improving SME's resource productivity and supplier selection under disruption risk. We discuss a framework of small medium enterprise (SME) management system for producing customized small size discrete manufacturing component that involves activities of shop floor production, monitoring, and controlling. As a company that positioned at third or even lower layer of supply chain, they try to catch up production level by an increasing number of working hours, which is also increasing manufacturing cost simultaneously. Furthermore, they are subject to a wide range of risks, such as natural disasters, terrorist attacks, and supply uncertainty. For them, integrated automation, supplier collaboration, and risk management against facility disruption are difficult challenges. We use graphical view of Petri net as an event based model, followed by a proposal of enabling technologies for integrated automation and credibility analysis for supplier selection. Finally, the numerical example and software prototype validate the effectiveness of the proposed system.
