支持复杂产品系统设计的虚拟知识流生成算法
Virtual knowledge flow generation algorithm supporting complex product systems design
摘要
Abstract
Complex product systems design involves many processes. Designer not only needs to master the knowledge of his/her own process, but also needs to understand the relevant knowledge of the other process. Ontology that represents complex product knowledge constitutes a formidable challenge for designers. Based on the workflow and ontology tech-nology, this paper designs a virtual knowledge flow generation algorithm to meet the knowledge needs of designers. The algorithm allows the designer to specify the starting concept, predicate and knowledge depth of each node of the work-flow, and then traverses the nodes to generate the virtual ontology view of each node to form a virtual knowledge flow that supports the knowledge needs of the designers, thus promoting the codified knowledge sharing of the designers. The algorithm is complete and independent of the starting concept order, the predicate directive is additive, and the computa-tion time increases linearly with the number of concepts in the ontology. Finally, the virtual knowledge flow in aircraft design is used as an example to illustrate the application of the algorithm.关键词
