本文介绍列车节能操纵优化研究的基本问题。基于求解方法的特征对已研究的方法进行分类，将其分为：解析方法、数值方法和仿真方法。分析各个方法的研究现状与投入应用的情况。解析方法求解速度快，且能得到理论上的最优解，为了保证存在有效解，需要进行简化处理；数值方法易于处理较复杂的目标函数，但求解得到的往往是局部最优，收敛性不能保证；仿真方法速度较慢，并不适于在线计算，但其思路简单，易于理解，是一种实用性较强的离线寻优方法。对列车节能操纵优化方法的研究前景进行了展望。

The basic issues of train trajectory optimization were introduced .The characteristics of the various ap-proaches to trajectory optimization were reviewed and the approaches were then categorized into three types :the analytical method ,numerical method and simulation method .The current studies and applications of the three methods were analyzed .The results show as follows :The analytical method is fast in calculation ,is read-y to get the optimum solution theoretically and needs to simplify the handling process so as to assure the availa-bility of the effective solution .The numerical method is suit for complicated objective function ,but often yields the optimum solution locally and its convergence cannot be guaranteed .The simulation method is too slow to be used for on-line calculation ,however ,it is simple in thinking ,easy in understanding and highly practical in off-line optimization .Finally ,the research prospect of optimization of train energy-saving driving operation was looked forward to .
