D Shen · Microcomputer Information · 2009
By going deep into the working way of large-screen system,and according to experts experience and failure mode which summarized by the system records,an expert system which applied rules automatic extraction methods based on the theory of rough set to large-screen system fault diagnosis,the expert system effectively simplified the fault features and the redundant information in the diagnosis results,solved the bottleneck of expert systems in the traditional knowledge acquisition,so the automatic obtainment of the diagnosis rules has been realized.
