A hybrid maintenance and inspection model is proposed for a series system with n+1 units subjected to two different failure patterns, which include deterioration and random shocks. The stationary laws for the failure process of the system are derived in order to evaluate the long-run average running cost on an infinite span generated by the proposed opportunistic policy. A periodic inspection is employed...
To investigate the optimal policy of continuously deteriorating system with economical dependence, a kind of improved opportunistic maintenance policy is presented in this paper. This system is composed of two kinds of units, which are subjected to the deterioration failure described by Gamma process and the Poisson failure respectively. The maintenance mode and corresponding control threshold are...
The optimal inspection and maintenance policy for the multi-unit series system with economical dependence is investigated in this paper. This system is composed of two kinds of units, which are subjected to the deterioration failure and the Poisson failure respectively. Since costs can be saved when several units are jointly repaired instead of separately, the optimal maintenance model for multi-unit...
