Abstract | Planing traceable policies to identify the failures is necessary for a complex system when a failure occurs with accumulated hidden failures. We give three cases of traceability problems in preventive maintenance policies: (a) the cause of failure is traced from the rst failure time t until time t + T if it has not been identied at time t + T; (b) The cause of failure is traced from failure K at time tK for an upper limit time T; (c) The distribution of tracing time depends on the time tK at the Kth failure. We obtain the expected tracing models for preventive replacement policies and nd optimum tracing time T analytically.
