一种基于GA-PSO算法的列车运行调整模型

摘要

本文针对列车运行时刻调整问题进行建模分析。首先，本文对该问题建立数学模型，并运用PSO算法对模型进行计算求解。在初步的求解过程中，针对 PSO算法的收敛速度较慢等不利因素对其进行优化，提出了 GA-PSO算法。最后，通过模拟实验得出GA-PSO在调度过程中能达到较高的准点率。%This paper makes model and analysis of the train running time adjustment. Firstly, it makes the mathe-matical model of the problem, and uses PSO algorithm to calculate and solve the model. In a preliminary solution proc-ess, to optimize PSO algorithm converging slowly and other unfavorable factors, GA-PSO algorithm is proposed. Fi-nally, simulation results show that GA-PSO in the scheduling process can achieve higher punctuality rate.
