基于语义关联度的复杂产品装配指令启发式设计

The heuristic design of assembly instructions for complex product based on the semantic correlation

为了实现复杂产品装配指令的启发式设计,通过深入分析复杂产品装配指令语义本体,提出了复杂产品装配指令语义相似度及语义关联度的概念,给出了复杂产品装配指令语义相似度及关联度分析方法,并基于本体层次结构中语义元素距离及概念属性因素,实现对装配指令语义元素的语义相似度量化分析及聚类,基于有向图理论,实现装配指令典型语义元素关联度量化分析,最终完成了装配指令的启发式设计。

In order to realize heuristic design of assembly instructions for complex product,it analyzes the assembly instruction semantic ontology of complex product,proposes the ideas of semantic similarity and semantic correlation,describes the analysis method on similarity and correlation of assembly instruction semantic. Based on semantic elements distance and concept attribute factors at the ontology hierarchy,it realizes analysis and clustering of semantic similarity about assembly instruction semantic elements. Based on the directed graph theory,it realizes typical semantic elements correlation of assembly instructions evaluation. Finally it achieves the heuristic design of assembly instructions.
