Risk of failures induced by deferred maintenance for a component under inspection policy

摘要

In this paper, an analytical model is developed for evaluating the risk of deferred repair under an inspection policy. The models of failures and risk evaluation are developed using probability, stochastic process and the delay time concept. The cases of perfect inspection and imperfect inspection are considered respectively. The performance of the proposed model is illustrated by an example, and the effect of time delay of repair on the risk is analysed.
