Optimal maintenance policy for a system subject to damage in a discrete time process
Maintenance Cumulative damage Expected cost rate Operation period Renewal reward theory
2012/4/15
Consider a system operating over n discrete time periods (n=1, 2, …). Each operation period causes a random amount of damage to the system which accumulates over time periods. The system fails when th...
