Abstract: It is significative on theory and application aspects to have a research on energy-saving operation of trains under the case of huge energy consumption of orbit traffic transportation. The mathematical optimal models for lowest energy consumption of single train, for energy saving operation of multiple train and for the train delaying multi-objective optimization control are set up based on analying the energy transformation mechanism of train running from the aspect of saving energy. To face the complexity of model and its constraint conditions, “Simulation optimization” method which based on the cuckoo optimization algorithm and dynamic search method is proposed, to solve the problem of train energy-saving operation strategies. Compared with other similar algorithms, the proposed method has certain advantages. The optimal speed-distance curve of train in various conditions is obtained, which is consonant with the practice. The improved search algorithm is more efficient, the research thinking and mathematical model will have certain realistic directive significance to energy-saving optimization of trains. The model-solving methods is reasonable and applicative for complex optimization mathematical model, which has certain?reference value.
