Multi-equipment maintenance decision-making method for high temperature reactor based on maintenance event correlation

The composition of the high temperature reactor system is complex, effective maintenance management strategy can reduce the number of shutdowns and reduce maintenance costs during the operation of the equipment and caused by deterioration, improve system reliability, and also avoid system failures, maintain or restore the system to the most appropriate standard of reliability, availability and safety. This paper proposes a methodology on maintenance decision making with target of minimal downtime by analyse the associated relationships of different maintenance activities to realize merge maintenance.
