基于本体的可适应性产品全生命周期管理系统

为了降低产品全生命周期管理系统的成本，提出了一种以本体论思想为基础，采用适应性对象建模方法构建的产品全生命周期管理模型。定义了一组本体元概念来表述产品全生命周期的本体模型；并以本体模型约束系统中数据的产生和应用。采用适应性对象建模的方法，在本体元概念的基础上建立了一个可重构的原型系统，该原型系统的行为是基于存储在系统外部的本体模型。通过改变系统本体模型定义，可以改变原型系统的行为。支持以迭代的方法建立产品全生命周期管理系统，降低了建立系统的成本。

Ontology based adaptive product lifecycle management system

To reduce the cost of Product Lifecycle Management (PLM) system, a PLM model based on Ontology and Adaptive Object Modeling was proposed. A set of meta-ontology concepts were defined to describe the ontology model of PLM, and the ontology model was applied to constrain the data in PLM system. The reconfigurable prototype system was built based on adaptive object modeling. The ontology model was interpreted by the prototype system at run time. As the ontology model was changed, the prototype system changed its behavior. So the iteratively construction of the PLM system was well supported and the cost of system construction was reduced.
