The maximum step wise fault detection, and artificial intelligence

For a system designed for stepwise maximum fault diagnosis, an algorithm is given to write down the requirements of fault diagnosis in terms of a complete set of axioms. The concept of artificial intelligence is studied and applied to the problem of fault diagnosis of the system. If the system has been designed for t₀ fault diagnosis without repair and if, after t₀ faults, the nonfaulty units of the system can diagnose t₁ additional faults where t₁⩽[t ₀/2], and after t₁ faults, the remaining nonfaulty units can diagnose t₂ additional faults where t₂⩽[t₁/2] and so on. The process of additional fault diagnosis in a stepwise manner will function, and the process will stop when necessary and sufficient conditions for fault diagnosis are violated
