Abstract
The invention provides an integrated optimization method for high-speed railway train operation diagram and motor train unit application, and belongs to the technical field of high-speed railway trainoperation control. The method comprises the following steps: constructing an integrated space-time continuation network; describing a running path of the motor train unit according to the integratedspace-time continuation network; establishing an integrated optimization model with a block diagonal structure according to the operation path of the motor train unit; and solving the optimization model based on a Lagrangian relaxation algorithm to obtain a motor train unit intersection and a high-speed railway train running diagram. According to the method, the train operation diagram is adjustedwhen the motor train unit is optimized to be applied, the integrated optimization model has an obvious block diagonal structure, the model is easy to decompose, and the coordination problem of the operation paths of all the motor train units is more rigorous; according to the Lagrangian relaxation-based model solving method, a large-scale combination optimization problem is decomposed into a plurality of sub-problems based on a motor train unit operation path, and the problem that an integrated optimization model cannot solve large-scale high-speed railway train operation diagrams and motor train unit application integrated optimization is solved.
Description
technical field [0001] The invention relates to the technical field of high-speed railway train operation control, in particular to an integrated optimization method for high-speed railway train operation diagram and EMU operation. Background technique [0002] With the improvement of my country's high-speed railway network and the rapid growth of the number of EMUs, the passenger volume of my country's high-speed railway continues to rise. For the scale of my country's high-speed railway network at this stage, the number of EMUs is still relatively small, which is a relatively scarce resource. The bottleneck of most high-speed railway transportation capacity lies in the limited number of mobile resources such as EMUs. In addition, the operating cost of EMUs Higher, the actual transportation process of the high-speed railway needs to consider the transportation cost. Therefore, how to optimize the high-speed railway transportation organization under the condition of a limited...
