Zhang Yan, Wang Jun, Zhao Yan. Extension of the Product Design Scheme and Knowledge Inference[J]. 2014, 31(4): 6-13.DOI: 10.3969/j.issn.1007-7162.2014.04.002.
Computer technology to simulate the extended thinking in product scheme design is adopted to devise quickly more design schemes with higher quality. An innovative principle for scheme extension was presented
based on Extension network. The Extension network was defined to integrate the extension rules. The probable conflicting forms and their resolutions of the Extension network were advanced. The knowledge inference system
involved when the principle was applied in the intelligent system
was given from the perspective of artificial intelligence/knowledge engineering. The inference algorithm for utilizing the inference rules
based on Extension network
was given. The validity of the algorithm was analyzed. A case study shows that more alternative design schemes can be obtained by applying knowledge inference
based on Extension network
which means more probability of innovation is provided.
