Embodiment Construction

[0080] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0081] The first is to design a graph theory model for the optimal arrangement order of train groups. This graph theory model is about transforming the optimal arrangement order of the train groups into finding the minimum Hamiltonian path of a directed graph, that is, a graph or a directed graph. The Hamilton road (loop) in is a road (loop) that goes through each vertex in the graph once and exactly once.

[0082] In the sequenced car train, each car group from the first group to the last group is an orderly arrangement; except the first group and the last group, each car group has a preceding sequence and a subsequent car group adjacent to it; In the sequence of trains to be compiled, if they are connected in turn with directed arcs according to the sequence after sequence, then there is a Hamilton road from the first group to the end group,...

Abstract

The invention discloses a plane switching operation hook planning compilation method for a middle railway station. A modularization structure is adopted. The modularization structure comprises a hook planning graph automatic compilation module, and is characterized in that the graph automatic compilation module is a graph theory model for designing an optimal train set arrangement sequence, wherein the graph theory model is about converting solving of the compiled optimal arrangement sequence into solving of a minimum Hamilton path of a digraph, namely, the minimum Hamilton path is a path passing each vertex of a graph or the diagraph only once.

Description

technical field [0001] The invention relates to a method for preparing a railway shunting operation hook plan, in particular to a method for preparing a plane shunting operation hook plan for a railway intermediate station. Background technique [0002] In the past, when compiling the shunting operation plan, the first thing to do was "the whereabouts of the train group", that is, to adjust the order, decompose the reverse order train group in the train train to be assembled to different lines. Then according to the situation of the vehicle group getting off the road, steps such as "combining whereabouts" are carried out to obtain the shunting scheme, and different vehicle group whereabouts schemes correspond to different shunting schemes. Therefore, the whereabouts of the train group has an important impact on the quality of the shunting scheme. [0003] If the order of the trains to be assembled is 1 2 1 2, it is required to arrange them in order. The situation of the tra...
