A survey of condition-based maintenance modeling of multi-component systems

This paper surveys the recent developments on condition-based maintenance (CBM) modeling of multi-component systems. The emphasis is on the deterioration modeling and maintenance policies of this problem. An analysis of important factors which may influence maintenance decisions is also given. CBM is known as a modern and effective maintenance technique which is based on the information collected from condition monitoring process. Multi-component maintenance in the context of CBM is a relatively new topic and is becoming popular in the literature. This paper aims to cover the most commonly used ideas in the modeling multi-component CBM, to classify and compare the policies discussed in existing literature, as well as to provide useful information for current state and challenges of this topic.
