______________________________________________________________________ Abstract: This paper considers an inspection problem of a production line subject to small stoppages and hard failures. We assume that the probability density function of time to hard failure is a function of the number of small stoppages which is modeled by a non-homogeneous Poisson process. An inspection for identifying the cause of small stoppages and the hard failure with repair activities will renew the plant item so

... inspection interval is the decision variable in this paper. The developed model was demonstrated through a practical case in a baking line. The model parameters were estimated using the moment matching method based on the subjective data obtained from the study.
