Abstract: Previous proposed models use preventive or protective approaches to attain satisfactory reliability for a system. In this paper the authors pursue a different approach: the corrective approach. Even though the preventive and protective approaches eliminate some faults, the corrective approach increases the reliability of the system by detecting faults which occur during a specified operation time interval. In the corrective approach, fault recovery is straigthforward. The authors introduce a particular kind of Petri net, the restricted Petri net (RPN), along with a set of definitions and theoretical results which enable RPN to be of use in fault detection processes.
Keywords: fault analysis; corrective approach; fault recovery; restricted net.
