The Fully Automatic Operation(FAO) system is the development direction of the current urban rail transit system, but the system changes and manual handling under the failure scenario will have an important impact on the capacity performance of the FAO system. The concept of resilience is introduced to analyse the capacity change of the FAO system after artificial intervention and failure impact. This paper proposes a quantitative assessment method for the resilience of the FAO system. This method is based on the function of the FAO system and combined with the complex network model. The shortest path length of the network model index is used to quantitatively express the resilience of the FAO system. Based on this method, this paper makes a quantitative resilience assessment of the telecommunication failure of the FAO system, and puts forward the improvement direction of the system function and the key links manual disposal that need to be paid attention to according to the verification results.

Keywords: Fully Automatic Operation (FAO), Resilience, Quantitative, Failure response, Complex network.
