摘要
专用线最佳取送车顺序的确定,有利于减少作业车在站非生产性停留时间,加速车辆周转。通过分析放射形专用线直达车流取送车作业特点,构造了该问题的染色体编码方式,采用轮盘赌策略进行染色体选择,以作业车在站最小停留时间作为适应度函数,设计了该问题的单亲遗传算法,并结合算例进行计算,结果表明,该算法求解直达车流取送车问题取得了较好的效果。
Optimal order of placing-in and taking-out of wagons is in favour of reducing wagons non-productivity time in station and accelerating wagons turnaround.According to the analysis of characteristics of the operations on placing-in and taking-out of wagons in actinoid private line,this paper proposed a chromosome presentation and realized the genetic algorithm for the problem.Combined with an example,the results illustrated that this algorithm could find the optimal or nearly optimal solution to the placing-in and taking-out of wagons in actinoid private line problem effectively.
