In the system-level fault diagnosis area, the fundamental problem of characterizing sequentially t-diagnosable systems in the PMC model has remained open for more than two decades. We resolve this problem by providing a complete characterization of such systems. Our solution to the characterization problem leads to the correct identification of optimal sequentially t-diagnosable D delta, k systems. Given a set of n units where n = 2t + 1, an optimal D delta, k system can be constructed with just n((left bracket) (t + 2)/3 (right bracket)) tests, rather than n((left bracket) t/2 (right bracket) + 1) tests-a previously misjudged bound. An efficient algorithm for identifying the set of faulty the proposed characterization, which is linear with respect to the number of tests in the system. 22 refs.
