Extended optimal preventive replacement policies with random working cycle

Reliability Engineering & System Safety, 2019
This paper investigates the preventive replacement policies for an operating system that works for projects at random times. The system is subject to shocks which arrive according to a non-homogeneous Poisson process. When a shock takes place, the system
