Improvement of evolution of the thinning ratio and the probability of failure from quantitative inspection date using Bayesian theorem.

Abstract

The outdoor structures such as the infrastructures are indispensable to human life. Periodical of the inspection is necessary 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. Then, in this research, quantitative evaluation method of probability of failure from quantitative inspection result using Bayesian theorem is proposed.
