Abstract In order to enhance the resilience of urban transit network system after being attacked by external factors, a resilience repair scheme for urban transit network system is developed. Firstly, urban transit network system resilience is defined and urban transit network system resilience model is constructed. The change of network system resilience after suffering from external attacks is divided into two phases: absorption and repair. In the absorption phase, the load distribution of the failed nodes is considered; in the repair phase, two types of network resilience repair schemes are developed according to the different intervention phases, namely, repairing while absorbing and repairing after absorbing. The urban transit network in Huangdao district of Qingdao is selected for simulation analysis to verify the feasibility of the rehabilitation strategy.
