基于本体映射的需求相似度产品配置研究

Research on Product Configuration of Requirement Similarity Ratio Based on Ontology Mapping

鉴于客户域与产品域间的语义沟通障碍,利用本体在语义推理、信息管理方面的优势提出了基于本体映射的产品配置方法。针对产品设计的继承性、创新性及客户的个性化需求,构建了客户需求本体和产品配置实例本体。通过本体中概念元素间的相似度计算,由相似度阀值、本体约束及上下文关系决定最优映射,最终实现了个性化产品的快速、准确配置,降低了产品设计过程的复杂性。最后,以某轿车的个性化产品为例说明该配置方法的可行性。

Considering the barriers of semantic communication between customer domain and product do- main, and the advantages of ontology in semantic reasoning and information management, a method based on ontology mapping is presented to implement product configuration. For the inheritance and the innovation of product design, and the customer individual demand, a customer requirement ontology and product family case ontology are constructed. According to the optimum mapping decided by the similari- ty threshold, ontology constraints and context relations, the individual product configuration is realized quickly and precisely through calculating the similarity ratio among conception element of ontology, and the complexity of the product design process is reduced. Finally, an example of a car is presented to demonstrate the feasibility of the proposed method.
