Optimal High-Speed Railway Timetable by Stop Schedule Adjustment for Energy-Saving

A Fuzzy Optimization Model for High-Speed Railway Timetable Rescheduling

A fuzzy optimization model based on improved symmetric tolerance approach is introduced, which allows for rescheduling high-speed railway timetable under unexpected interferences. The model nests different parameters of the soft constraints with uncertainty margin to describe their importance to the optimization purpose and treats the objective in the same manner. Thus a new optimal instrument ...

Energy-constraint Operation Strategy for High-speed Railway

With given trip time on each section, conventional train energy-efficient operation problem optimizes the reference speed profile such that the energy consumption for tracking the profile is minimized. Alternatively, this study aims to solve its anti-problem that minimizes the trip time under certain energy constraint, namely the train energyconstraint operation problem. In particular, this stu...

Railway Passenger Service Timetable Design

The aim of this paper is to analyze and to improve the current planning process of the passenger railway service. At first, the state-of-the-art in research is presented. Given the recent changes in legislature allowing competitors to enter the railway industry in Europe, also known as liberalization of railways, the current way of planning does not reflect the situation anymore. The original p...
