【摘要】 针对家电企业产品生命周期管理中产品设计存在着手工建档、查询困难和协同性差的状况,将本体理论引入家电领域。在研究家电领域顶层本体构建方法和本体语义扩展方法的基础上,提出功能语义扩展方法 isa,构建功能本体;采用OWL(Ontology Web Language)语言对家电产品设计知识进行表达,构建以用户需求为导向的索引知识库;采用映射方法和相关度匹配方法对用户需求与本体知识索引进行转换,实现语义共享。最后以文中索引知识模型构建某家电企业设计知识共享平台,表明该模型是可行的。更多还原

【Abstract】 To solve the manual file condition of product design of PLM in household electrical appliance enterprises,which is difficult for querying and cooperation,the Ontology theory is introduced into the field of home appliances. The functional semantic extending method is presented and used to construct a function body based on top- level ontology construction method of home appliances and extension method of ontology semantic. The index knowledge repository model of user demand- oriented is constructed. The home appliance product design knowledge is expressed by using OWL language. The user needs and ontology knowledge index are transformed by the method of ontology mapping and matching of similarity to realize the sharing of semantic. Finally,to verify the correct of the index knowledge model,the knowledge sharing platform is established by product design for refrigerator enterprise.更多还原
