鋼材表面状態の定性検査データからのベイズ法を用いた破損確率評価

The outdoor structures such as the infrastructures are indispensable to human life. Periodical usually inspection is used to prevent those failures. However, those numbers are enormous. Therefore, the adjustment of the inspection interval is necessary by a probability of failure evaluation. Since the qualitative visual inspection is mainly used as the inspection method for the infrastructure, quantitative evaluation of probability of failure is difficult but important. Then, in this research, quantitative evaluation method of probability of failure from quantitative inspection result using Bayesian theorem is proposed.
