摘要
The spacecraft launch system is not only one of the most basic and the most important parts in human space activities but also an important indicator for judging a country's overall national strength. The operational safety assessment of the spacecraft launch system can be considered as the core of modern spacecraft launch control command and decision system. It is the basis for ensuring the safe operation of spacecraft launches. The modern spacecraft launch system is outlined and the development of system safety research is briefly reviewed. The connotation of the operational safety assessment of the spacecraft launch system is explained. Secondly, it focuses on the research progress of operational fault detection and diagnosis, abnormal operational condition identification, operational processes safety analysis and prediction, safety dynamic evaluation technology. Additionally, the challenges on the operational safety assessment of spacecraft launch system are discussed, including extremely complexity in practical system, great risk in decision-marking, little prior information, high accuracy and real-time evaluation results. Finally, the basic and systemic issues of the future research for the operational safety assessment of spacecraft launch system are pondered. Copyright © 2019 Acta Automatica Sinica.
