Abstract

In this paper, we study the relationship between multiple faultdiagnosability and fault detection count. Instead of developing acomplex diagnostic algorithm for multiplefault behavior, we changethe test sets used in test and diagnosis. This allows us to apply asimple single-fault based diagnostic algorithm, and yet achievevery good diagnosability for the failure test cases caused bymultiple faults. We have verified experimentally the effectivenessof n-detection tests for multiple-fault cases and explained theresults in probabilistic terms.
