基于元模型的产品全生命周期信息模型研究

Research on Product Lifecycle Information Model Based on Meta-model

在分析产品元数据语义关系的基础上,从结构层、过程层和表达层描述了全生命周期信息模型,提出了基于属性、约束和操作表达的信息模型,分析了元模型扩展机制与领域模型建立方法,并以汽车减震器为例,阐述了信息模型的建立方法与应用。

For the purpose of seamlessly integrated product lifecycle information and sharing knowledge, an integrated, reconfigurable, extensible and highly coincident product lifecycle information model was needed. On analyzing semantic relationship of product meta--data, the lifecycle information model was described from structure layer, process layer and representation layer, and based on attributes, constraints and operations an information model was proposed. Then we analyzed the mechanism of expanding meta--model and the method of building domain model. At last an information model of shock absorber was established and applied as a sample.
