【Abstract】 In this paper, the Engineering Change Management (ECM) module is developed, based on the Web-PDM system designed by Department of Precision Instruments and Mechanology of TsingHua University. On the basis of ECM’s function model and work-flow, the data objects model is established. This paper gives more discussion about EC workflow collaboration and version update and presents a program control frame about workorder ID management in different fields.更多还原
