Fuzzy dispatching model and genetic algorithms for railyards operations

In this paper, we present a fuzzy dispatching model to assist the coordination among multi-objective decisions in railyards dispatching plan. The objectives considered here are to maximize railyards output and on-time service of the dispatching plan. Genetic algorithms are used to investigate and analyze the fuzzy dispatching model. Experimental results based on real-world problem instances show that the combined, genetic algorithms and fuzzy theory approaches could be a promising way for solving railyards dispatching problem.
