ABSTRACT
<p><b>Abstract</b>—In this paper, we introduce a new model for diagnosable systems called (t,k)-diagnosable system which guarantees that at least k faulty units (processors) in a system are detected provided that the number of faulty units does not exceed t. This system includes classical one-step diagnosable systems and sequentially diagnosable systems. We prove a necessary and sufficient condition for (t,k)-diagnosable system, and discuss a lower bound for diagnosability. Finally, we deal with a relation between (t,k)-diagnosability and diagnosability of classical basic models.</p>
