Event-Based Production Process Traceability Model

Precision tracing of complex production process is one of the difficult problems in manufacture execute system. In this paper, an event-based production process traceability model is proposed, the key idea of which is to define several meta event according to the characteristics of production process and draw a composite event from real production activities, then divide the composite event into several meta event and use attribute of event to create links with relevant events. Finally, the traceability information can be acquired by searching the event link set
