Data collection and management method for discrete assembly process of complex product

To solve the problem of data collection and management in discrete assembly process of complex product, by introducing the workflow management technology, a process model of data collection and management based on analysis of assembly data collection flow was presented. A workflow based assembly data collection and management method was proposed, and data collection process definition, data collection process instance generation as well as data collection process control were realized. Several key technologies such as dynamic customization of collection forms, accessing and organization of heterogeneous colleted data and technology oriented data collection and management were particularly illustrated. The feasibility of proposed method was proved by actual engineering applications.
