Complex repairable system models address the dynamics of the failure and repair process. These models arecritical to the maintenance optimization. This paper firstly discusses different repair effectiveness. Imperfect repair is considered as the most frequently occurred repair effectiveness. Later on this paper surveys the developedimperfect repair models in state of art. It reveals current models...
A geometric process delta -shock maintenance model for a repairable system is introduced. If there exists no shock, the successive operating time of the system after repair will form a geometric process. Assume that the shocks will arrive according to a Poisson process. When the interarrival time of two successive shocks is smaller than a specified threshold, the system fails, and the latter shock...
