Summary: | The concept of availability importance measures can be used to identifying critical components from the availability performance point of view. The availability of an item depends on the combined aspects of its reliability and maintainability performance indices. These indices are considerably affected by operational and environmental conditions such as; ambient temperature, precipitation, wind, etc. Thus, different subsystems or components’ availability in various conditions changes the performance priority of the system. In this way, the paper used the availability importance measure considering the operating environment for a mining fleet consisting of one shovel and six trucks. The reliability and maintainability characteristic of machines considering all influence factors (covariates) is analysed using by Cox regression model. The availability importance measure in two scenarios demonstrated that subsystem criticality changes in various conditions and the appropriate decisions should be made on different operational conditions. |
