The Study On The Key Technologies Of Web-Based Product Cooperative Development Process Management

The collaborative product development technology has become one of the crucial methods by which modern manufacturing enterprises can enhance product development capabilities and improve the competence in market. The collaborative product development environment, partners and purposes are changing among dynamic alliances. In order to manage the total process of the development, an effective process management must be carried out. In this dissertation, we study deeply the key technologies of the framework structure, application technology and system realization for collaborative product development process. The content of this dissertation mainly includes:In the dissertation, the collaborative product development process management model is given first. Then, the features of modern development process are defined, and the demand of process management modeling is discussed. Some relative theories of product process management modeling and several popular models are developed and all compared. Based on all of above, a multi-view model is consequently proposed.Secondly, the collaborative product development process and management system are constructed. After analyzing the running environment, the design of the system frame and a theory of process decomposition are brought out, and the execution mechanism of the process is studied. So, the whole running programs are established.Thirdly, the supporting technologies for collaborative product development process and management system are integrated. Consequently, the collaborative supporting effect of distributed workflow and task management technology regarded as management tools in the course of collaborative product development process are introduced and analyzed in detail. A task model concluding production process characteristics is given, meanwhile three task object models and specific features of different level task are bringed out. According to the model structure, the collaborative development task model aiming to sub-task object management and design of the corresponding XML-based task management system are put forward. Finally, two key technologies in the development are summarized. In order to share the data in heterogeneous systems, a model for data syncretizing of the process is developed. XML-based data exchange is realized and the distortion during the exchange is discussed.In conclusion, based on the theory given in the dissertation, and the system is exploited and validated. Then the system structure is built up, and the interface between the frame and the system are showed, and the development methods are descriped. So that the whole PCD-PMS is accomplished. The system now is tested in a factory.
