Research of product design knowledge model based on knowledge fusion
基于知识融合技术的产品设计知识模型研究*

To solve knowledge fusion from different resources in mechanical design,proposed a product design knowledge model based on ontology model.Based on the model,used an algorithm for knowledge fusion which combined with Dempster-Shafer evidence theory and fuzzy set in fusion reasoning.It introduced the fuzzy set into the evidence identification space and used the rule of evidence combination and decision which improved the effects of evidence combination.Used the fusion algorithm to make up the lack of ontology...
