The Decision-Making for Fault Diagnosis Based on Consistent Approximation Space

摘要

Due to vary kinds of factors,test results for a weapon system may be incomplete and hard to make decisions for fault diagnosis.Aimed at the problem of the weapon system inconsistent decision-making for fault diagnosis,introduced the method of consistent approximation space.Firstly the definition of inconsistent decision-making information system was brought forward,and then the consistent approximation space was formed.Attribute reduction for the consistent approximation space and an approach for rule amalgamation were also presented.Finally,a case was used to prove this method; the result shows that the method of consistent approximation space can solve the inconsistent decision-making for fault diagnosis problems effectively.
