Fuzzy algorithm for real-time train dispatch and control

This paper discusses a knowledge based system that uses fuzzy set techniques to plan train circulation in freight railroads. Its purpose is to aid train dispatchers in decision making and traffic control in real time. The system uses decision procedures based on fuzzy rules with the purpose of driving train circulation as closed as possible to reference trajectories. It can easily incorporate operational knowledge and dispatcher experience as a part of the decision making strategy. A major characteristic of the system concerns its ability to provide feasible circulation plans in real time. Incorporation of practical knowledge and real time response are key requirements for control and traffic management in train control rooms.
