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.
