A fuzzy optimization model based tolerance approach is proposed to handle timetable rescheduling in high speed railway during speed restriction period. As the limited speed and headway time are not crisp figures in practice especially when some natural hazards happen or some equipment failure, tolerance approach is introduced with the fuzzy membership functions of the original objective and soft constraints...
The organization of the high speed railway is most important in China today, while the line planning step is the key to make the high speed railway system to run safely. It is urgent to find a new method to generate a robust line plan for high speed railway to adapt with the randomly occurring disturbs. A model is built in this paper and the approach to select the most robust line plan is discussed...
