Application of automatic knowledge of rough set theory In 04 caterpillar infantry chariots fault diagnosis expert system
Ying Li · Electronic Design Engineering · 2013
Based on the rough set theory,caterpillar infantry chariots fault diagnosis expert system achieve knowledge of automatic acquisition.First of all,based on historical failure data,establish a decision table,and take advantage of data mining algorithm of rough set for the attribute reduction of decision table,eliminating the redundancy of decision table.The decision rules is obtained,take advantage of the attribute value reduction algorithm for attribute value reduction.Knowledge base is composed of condition table,the conclusion table and fact table,saving in the Access2003.The condition attribute kept in the condition-table of the knowledge base.The decision attribute kept in the condition-table of the knowledge base.it is convenient to establish the knowledge base.
