High-speed railway operation network elasticity capability assessment method based on multi-network integration

The invention provides a high-speed railway operation network elasticity capability evaluation method based on multi-network integration. The method comprises the following steps: constructing a high-speed railway operation network model based on a physical network, a function network and a demand network; simulating a scene in which the physical network is impacted, determining affected traffic flow distribution by using the connection between the function network and the physical network, and determining affected passenger flow distribution by using the connection between the demand network and the function network; and generating a transfer scheme for the passenger flow affected by the demand network on the function network, constructing a high-speed railway operation network elastic capability evaluation model taking the passenger travel service rate under the influence of uncertain factors as an index, and optimizing and adjusting the infrastructure construction and train timetable of the high-speed rail
