REVERSE ANALYSIS METHOD FOR MIXED DETERIORATION BY INVERSE BAYESIAN BELIEF NETWORKS MODELING TECHNIQUE

摘要

PURPOSE: A complex deterioration reverse direction analytical method of a structure using a reverse direction BBN(Bayesian Belief Networks) modeling technique is provided to calculate an efficient factor which extends the lifetime of a structure by analyzing fatigue lifetime. CONSTITUTION: A target fatigue life of a structure is set up. The value of fatigue life factors is measured(S10). A safe area of fatigue life influence factors for the implementation of the purpose fatigue life is calculated(S11). A maintenance cost required to the complementary of fatigue life influence factors is calculated(S13).
