Abstract
Purpose
The purpose of this paper is to generate line plan in emergencies for railway networks to complete the passenger transportation.
Design/methodology/approach
The authors first build a mathematical model, focusing on the frequency setting and stops setting. Then, considering the OD passenger flow data, the authors first propose the method to solve the train frequency setting problem of different types. Genetic algorithm is designed to solve the stops setting problem. The approach is tested with the data from Beijing-Shanghai high-speed railway and its neighbour existing railway.
Findings
The authors find that the model is suitable to generate line plan in emergencies for railway networks and the algorithm has good calculating performance.
Originality/value
The new algorithms to generate line plan proposed in this paper can be embedded in the decision support system for railway operators.
