OPTIMAL MAINTENANCE OF SEMI-MARKOV MISSIONS
Probability in the Engineering and Informational Sciences, 2014 We analyze optimal replacement and repair problems of semi-Markov missions that are composed of phases with random sequence and durations. The mission process is the minimal semi-Markov process associated with a Markov renewal process. The system is a complex one consisting of non-identical components whose failure properties depend on the mission ...
