Multifault Diagnosis in Dynamic Systems

In this paper, we address the problem of diagnosing multiple faults in dynamically changing systems. Currently used popular techniques such as codebook and active probing suffer from limitations imposed by their ”static”, non-temporal nature, and single-fault assumptions. We propose a very simple, linear-time multifault scheme, capable of tracking system changes and diagnosing multiple faults much more accurately than previously used approaches. We provide empirical results demonstrating the advantages of our approach and analyze the effect of test set quality on the diagnostic accuracy.
