A novel condition-based maintenance framework for parallel manufacturing systems based on bivariate birth/birth–death processes

This paper addresses a condition-based maintenance scheduling for a continuously monitored manufacturing system. In such a system, each unit is subject to deterioration, which is modeled as a continuous-time Markov process with two working states and a failure state. Maintenance is initiated when the system state falls into a state with a pre-specified number of failed units. We develop a novel framework to find the optimal policy using a …
