The objective considered here is to maximize the average grade of satisfaction including the yards output and ontime service of the plan. Based on the analysis of the fuzzy scheduled model for the problem, the chromosome and fitness function of genetic algorithms are proposed. The genetic operators are designed and the genetic algorithms are given. Experimental results show that the genetic algorithms and fuzziness approach could be a promising way for railyards dispatching problem.展开更多
