Train operation adjustment and optimization method under fixed train path sequence

Abstract

The invention provides a train operation adjustment and optimization method under a fixed train path sequence. The method comprises the following steps: configuring a railway line topological structure and a space-time network corresponding to the railway line topological structure; configuring an initial train operation plan, train operation basic data and fixed train path data; according to the railway line topological structure, the initial train operation plan, the train operation basic data and the fixed train path data, establishing a train operation adjustment and optimization model under a fixed train path sequence based on a space-time network; and solving the train operation adjustment and optimization model under the fixed train path sequence by using an integer programming algorithm, and obtaining a train operation adjustment plan with the fixed train path sequence. According to the method, the optimal train operation adjustment plan can be generated under the condition that the sequence of partial train paths is fixed, the interference of complex factors difficult to describe on train operation can be effectively reduced, and the work complexity of train dispatchers can also be reduced.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to a train operation adjustment and optimization method under a fixed sequence of train operation lines. Background technique [0002] In the process of train scheduling decision-making, in addition to the external disturbances caused by severe weather such as strong winds and rainstorms, there are many other disturbances. Difficulties, which have brought greater challenges to the train dispatchers who originally had high work intensity. [0003] In recent years, with the improvement of the quality of railway transportation services, the railway dispatching command is facing higher requirements, which requires the formulation of train operation adjustment plans to be more detailed and robust against various complex external disturbances. However, the train operation adjustment plan cannot take into account all the complex factors faced by the train in the actual ope...
