M odel ofRailway Transportation Channel Share Based on Finished Dedicated Passenger Line

To sufficiently give play to the transportation capability of railway transportation channels consisting of a dedicated passenger line and an existing line, factors influencing the share of railway transportation channels were analyzed, and a mathematical model of railway transportation channel sharewas setup. In thismode,l the optimal object is transportation cos,t traveling speed and routine transportation regulation, and the restriction condition is carrying capacity. In addition, thismodelwas improved by using the satisfaction optimization, themulti-objective optimizationwas transformed into a single objective optimization problem, and the corresponding algorithm was given. The research provides a theoretical reference for the share of railway transportation channels.
