Comparison of two maintenance policies for a multi-unit system considering production and demand rates

In this paper, two new condition-based maintenance policies are developed for a multi-unit system. This study integrates maintenance, production and demand into a single model. The system consists of N identical, independent units, each subject to gradual deterioration. Production rate of each unit varies in different working states and demand rate of the system is assumed to be constant. Cost of sending maintenance crew to perform maintenance …
