Abstract :
D-matrix is the basement of large-scale-system equipment test and diagnosis. In order to cover the shortage of D-matrix information in TEAMS model construction, Advanced D-matrix is proposed, reflecting the nature of Equipment and solving the problem that could cause confusion in signal invalidation of D-matrix fault definition. A method to get advanced D-matrix data from multi-signal model is given. Application shows that advanced D-matrix can produce a correct conclusion on the condition that some part of signal invalid and other normal. Analysis comparison between two kinds of D-matrix testability index is made last.
