Understanding Theories and Methods on Equipment Operational Reliability Assessment

Operating reliability has great significance for equipment condition monitoring and health evaluation. In terms of equipment to be evaluated, reliability assessment is a personalized problem. Traditional reliability assessment method relies on the probability and mathematical statistics methods, and has limited practical significance when it is used for real-time monitoring of a specific equipment. In this paper, the characteristics and challenges of operational reliability assessment for large equipment are analyzed, and the methods and improvements in this research are summarized. In general, the operational reliability assessment methods are divided into two categories, which are model-based methods and mapping-based methods. In the end, some suggestions are given for future research directions.
