Abstract

The invention relates to a train scheduling strategy self-adaptive selection method based on an adjustment result. The method can be used for automatic generation and selection of scheduling strategies. The method comprises two parts of scheduling strategy generation and scheduling strategy identification. Wherein the scheduling strategy generation comprises a clustering result analyzed by utilizing big data; a scheduling strategy and a scheduling result feature set of the scheduling strategy are automatically generated, scheduling strategy recognition comprises the steps that a scheduling strategy selection problem is converted into a feature recognition problem, and the scheduling strategy is automatically matched through a machine learning algorithm according to result features of a train operation adjustment target. Compared with the prior art, the method has the advantages that the universality and result predictability of the method are enhanced, and the like.

Description

Technical field [0001] The invention relates to train operation control technology, in particular to an adaptive selection method of train dispatching strategy based on adjustment results. Background technique [0002] The main purpose of train operation adjustment is to make the train run in accordance with the pre-planned operation chart as much as possible, and to reduce the impact of emergencies on the service party and passengers. As the focus of the research on train operation organization, the method of train operation scheduling has relatively fruitful results in the research method and content. These studies mainly focus on the following aspects. [0003] Modeling based on operations research methods. This method is to give certain assumptions to the problems encountered in train adjustment, establish a mathematical model, and then use genetic algorithms and annealing algorithms to find the optimal solution to the model. The general logic of the mathematical norm of thi...
