Technology Research & Realization Of PDM Multiple Workflow Management For Middle And Small-Sized Enterprises

The paper mainly studied the practicing technology of multiple workflows in PDM system. It applied the combination of structarization and object-oriented methods, then designed the management module of multiple workflows, developed a PDM multiple workflows tool which is simple but useful oriented to the middle and small-sized enterprises.The paper made the research of workflow management and related technology from various angles, and also explored some key technology problems exited in them. The research indicated that, the monopole workflow has single function which cannot satisfises the working request of the designing department in the enterprise. However, the combination of management technology of workflow, configuration management of the products and the product designing progress will raise both the product designing efficiency and enterprise management efficiency.In the course of the software programming, Based on the requirement of manufacture enterprises, using computer technology, communications technology, network technology and database technology, the author studied the realization and tools for workflow management and developed the model for multiple workflow management in the PDM system, Including the structure, function, model and database, etc. This thesis is organized as following:1. Summarized the research results of PDM system and workflow management technology;2.Analysed the basic theories of workflow management, discussed some key technology questions about workflow management technology and application in detail;3. developed the multiple workflow management model, with friendly user interface, quick reaction, easy to operate, it met the requirement of manufacture enterprises;...
