Abstract: This paper established a decomposition hierarchical network model of project level collaborative design process, based on work breakdown structure WBS, for character complex product collaborative design in dynamic alliance. The workflow of product collaborative design was established using time sequence Petri net, and the key assignment which has influence on design schedule and all design time were solved, after analyzing and comparing existing model method of collaborative design. And then experiments were used to verify. Theses technology support time management of workflow in project collaborative and shorten development cycle of collaborative project.

Abstract: Aim at an existent problems of manufacturing enterprise data exchange between design and manufacturing software, this paper puts forward the solution of data exchange between heterogeneous database with XML, which is based on the systematical analysis of currently data exchange methods between heterogeneous databases, construct the data exchange model between heterogeneous database based on XML. It gives mainly mapping method which is used for data exchange between XML and relational database, and analyzes the algorithm of connecting relational database, in order to solve the problem of transparently interoperation of heterogeneous database and realize data integration and sharing between manufacturing enterprise heterogeneous database. So it provides effective methods.
