Knowledge Push Technology for Complex Mechatronic Products Design Based on Ontology and Variable Precision Rough Set
Fa Lin Wang, Guo Yu, Wen He Liao, Bao Sheng Wu · Applied Mechanics and Materials · 2015
In this paper, we present a new knowledge push technology for complex mechatronic products design based on ontology and variable precision rough set (VPRS). Ontology can explicitly represent knowledge semantics and let designers exchange knowledge about design and the product development process; while using the knowledge reduction method based on the VPRS method, the design knowledge repository is simplified and design rules also be distilled from the reduct design knowledge repository. On the basis of the above approach, multiple designers can efficiently share design knowledge and can obtain appropriate design knowledge during all design processes. Finally, a case is employed to validate the proposed method of this paper.
