【Abstract】 In order to support the multidisciplinary design optimization in a complex engineering system, an intelligent product data server environment is established. It is made up of intelligent product model, context model, analysis model, communication service and network service. Users can define the product optimization tasks by the engineering structure control model (ESCM) which permits a top-down approach to design and permits system level requirements to flow down to drive the product model. The integrality of the product data can be offered by the feature-based master model. The high-fidelity analysis models that are abstractions of the master model are produced by the design task context model which is a business object. The consistency between the master and the analysis models is provided by a data associated environment. The product data is encapsulated by a collaboration data object and is published in WEB services. Thus the designers can transparently access the product data by NETWORK. To implement the collaborative product development by INTERNET, the product data can be visualized in the OpenHSF′s stream format.更多还原
