内容摘要：As one of the name cards of China's “Going Out” initiative, the high-speed rail (HSR) has undergone rapid development in recent years. The operating speed and other technical indicators have been continuously improved, meanwhile this renders the availability of HSR increasingly important. HSR availability is directly related to its reliability and maintainability, and has a significant impact on its safety, economy and sustainability. Chinese HSR has several years of operating experience and accumulated large amount of first-hand data with wide coverage, which serves a good foundation for data-driven theoretical research on its availability. On the other hand, the complex and dynamic natures of HSR system pose challenges to the new theoretical studies. This talk will focus on the latest real-world problems and challenges raised from HSR practice. In particular, it will introduce the recent research progresses from the following four aspects: system reliability design optimization, system status online monitoring and fault detection, system reliability assessment and prediction and maintenance optimization.
