Research on Optimization Model and Algorithm of Initial Schedule of Intercity Passenger Trains based on Fuzzy Sets

The initial schedule of passenger trains is the base of train working diagram . Taking the maximization of passenger satisfaction as the objective function and considering some constraint conditions such as the coordinate utilization of arrival and departure tracks and train-set joining time, etc, a mathematics model for optimizing the initial schedule of intercity passenger trains is constructed based on fuzzy sets. Furthermore, a heuristic genetic algorithm is designed to solve the model and the example is proposed to prove the effectiveness of the model and algorithm.
