[ 2 ] - بهینهسازی نگهداری و تعمیرات پیشگیرانه در یک سیستم چند وضعیتی
In this paper, we study the maintenance method in a system. We also consider a system that begin at time zero with most efficienty. After the first failure it is repaired, but we assume that the lifetime of the system is stochastically less than its lifetime at time zero. It is repaired after the second failure and after the third failur it is checked whether the system should be dismanteld or co…
