The problem of selecting test points of a missile attitude stabilization subsystem is researched.At first,using the concept of entropy in the information theory,an algorithm of the maximal fault diagnosis information value,considering reliability and testing cost,is presented based on the pertinence model.Then,test points can be selected based on the information value,a more efficient fault diagnosis strategy can be constituted,and a fault isolation tree is drawn.The application example shows that the method is correct and feasible,the strategy needs fewer testing costs.
Key words： pertinence model; reliability; testing cost; entropy; information value
