Abstract: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 reasoning and help solve the reasoning of uncertainty knowledge. The knowledge model is successfully applied to manufacturing product design, and as verified, it’s an effective solution to help the manufacturing enterprises shorten product design cycles and improve the product development quality. Furthermore, it’s much better for designer to share and reuse product design knowledge.......
