基于数据挖掘的机构设计知识库建立及求解

The Establishment and Solution of Mechanism Design Knowledge Database based on the Principle of Data Mining

分析了机构设计特点、步骤及设计知识构成,提出了基于数据挖掘原理的多维立方体数据模型及形成的知识库;该知识库根据功能分析法由实体层、方法层及创新工具库组成,便于查询,利于创新方案的生成;介绍了求解知识库的数据挖掘系统的组成及决策树算法;最后以一设计实例说明了知识库求解的过程。

The characteristics,steps and knowledge formation of mechanism design are analyzed,and the multidimensional cubic data model and its knowledge database based on the principle of data mining are proposed. According to function analysis,the knowledge database is composed of solid layer,method layer and innovation tool base,it is easy to query. Based on the formation of innovation scheme,the data-mining system construction of knowledge-database solution and its decision tree arithmetic are introduced. Finally an example is given to illustrate the process of the knowledge-database solution.
