摘　　要：提出了一种支持复杂工程系统多学科协同设计优化的产品数据管理方法及基于系统优化任务的智能产品模型数据组织模式。通过工程控制结构模型 ,定义了产品优化任务 ,并为设计任务自顶向下进行产品模型控制提供了途径。利用产品主模型技术实现数据的完整性 ,通过设计任务的语境模型产生数据高保真的分析视图以及关联数据环境实现产品主模型和分析模型的一致性。整个产品数据通过协作数据对象的封装 ,以 WEB服务的形式 ,使优化设计人员通过网络透明地获取产品数据。为了支持基于 INTERNET的协同产品开发 。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.
