Integration Technology for Complex Product Development Process

To improve the efficiency of complex product development, an integration model of five-dimension space based on project activity was presented. In view of the link role of activities, mapping relations among the spaces were constructed to analyze the function module in the different management system. By defining activity-flow, workflow, knowledge-flow, data-flow and resource-flow, the processes of function implementation in the corresponding space were analyzed, and the Push-Pull processes of knowledge and resource were introduced. According to the implementation technology of the sharing database, the information integration for five-dimension space was analyzed, and their associate relations were formulated through the standard AND-OR expressions. Finally, the inference rules of process logics were described through the expressions. This integration technology provided a platform for the implementation of knowledge Push-Pull technology and resource Push-Pull technology, and technical support for the rapid design of complex product.
