Train Rescheduling on Single-track Railway Model Based on Fuzzy Comprehensive Optimization

摘要

To give the efficient and feasible timetable when emergencies affect the train operation, train rescheduling on single-track railway line is studied. The generalized delay punishment cost and the timetable stability are taken into consideration when the objective is designed. They are firstly turned into general indices-satisfactory degrees and combined by the weights set to them to form a unique objective, using partitioned fuzzy membership function. And the constraints are listed for train rescheduling on single-track railway line, including interval time in block sections and at stations, earliest outbound time of passenger trains at stations, tracks number, assignment constraint, etc. The model is a new one, combining the delay time punishment and the timetable stability. It is an importance reference for the dispatchers.
