摘要
基于事例推理是解决DFA和装配工艺规划问题的有效方法,装配体检索是应用此方法的关键步骤.对装配体中的联结关系进行表达和分类,提出联结关系定量的比较方法,基于二分图理论建立了装配体之间的相似计算模型,给出了装配体检索过程和计算实例.
Case based reasoning (CBR) is an effective method to solve DFA and Assembly Planning problems, while assemblies retrieval and indexing is a primary step to its application. In this paper, the connection relations of assemblies are formally expressed and categorized, and then quantitative method for comparing two connection relations is proposed. Based on bipartite graph theory, similarity calculation model of assemblies is constructed. Assemblies retrieving process is described and a computation example is presented.
