Abstract

The invention provides an energy consumption calculating and scheduling method of an urban rail traffic system. The method includes the steps of establishing a multi-layer network model of the urban rail traffic energy consumption system on the basis of the urban rail traffic system; calculating topological properties and data properties of nodes as input, wherein the topological properties include the degrees, betweenness and clustering coefficients of the nodes, and the data properties include the energy consumption and strength of the nodes; fusing the topological properties and data properties of the nodes through an OWA operator to obtain the weights of the nodes in the urban rail traffic system; calculating the energy efficiency emergence state, namely the energy efficiency representation parameter, of the urban rail traffic system in combination with the weights of the nodes through Choquet integrals on the basis of the emerging theory; regulating and controlling the energy efficiency of the urban rail operation system on the basis of the energy efficiency representation parameter of the urban rail system. For the complex-structure urban rail traffic system, the energy efficiency of the urban rail system can be calculated by means of the method, and the reasonable regulation and control of the energy efficiency of the urban rail operation system are realized in combination with the calculated energy efficiency.
