摘要: In the theory of t-fault-diagnosable systems, one first chooses a set diagnostic tests, then seeks results these and finally proceeds to use test identify faulty units assuming that number does not exceed t. Nakajima was suggest departure from this practice. He proposed adaptively choose tests seek their until can fault-free unit. This unit may be used as tester all units. paper, we exploit idea fully show needs at most (n + 2t −2) adaptive in system with n The impact applications various models diagnosis algorithms is examined.
