Abstract
Focusing on the issue in railway route profile optimization, this paper established a railway route profile optimization model based on genetic algorithm. The conclusions and achievements of this research are as follows:( a) On the basis of the initial scheme of railway route profile, the efficiency and quality of railway route profile optimization can be improved by the use of genetic algorithm. ( b) Taking the mileage and design elevation of the gradient change point as the variables of design optimization, and after analysis on route profile design connotation, this paper established a multi-object fitness function based on genetic algorithm. ( c) In this paper, after evaluation on population diversity, a self-adaptation adjustment strategy of operational probability was determined in relation to selection operator, crossover operator and mutation operator. ( d ) On the basis of research on route profile optimization theory, a computer program for route profile optimization based on genetic algorithm was developed in this paper by the use of VC.
