| Abstract: | A new safety performance evaluation of the fault-prediction technology was researched based on misclassfication cost.First of all,a misclassification cost model for the statistical data of two fault-classificatory sets was constructed based on the inaccurate characteristic of probability theory,and the fault-direction decision rules of the running state were established by considering the minimum misclassification cost.Secondly,a misclassification cost model of numerous fault-classificatory sets was constru... |
