Abstract :
Motivated by the need to increase the availability of systems, the primary focus of diagnosis in field maintenance is to locate the faculty modules. The authors consider the problem of constructing optimal test sequences to diagnose faults in such modular systems. This generalized test sequencing problem is solved by an AND/OR graph search procedure, wherein information-theoretic heuristic evaluation functions are modified to account for modular fault diagnosis. The effectiveness of the algorithm is demonstrated on various test cases
