| 摘 要： | 根据铁路集装箱运输的特点,对空箱调运问题进行了分析,并设计了遗传算法求解这类问题.采用整数矩阵编码,通过对父代染色体的线性组合取整运算作为交叉算子,并做适当调整以保证解的可行性,同时利用矩形闭合回路调整调运量作为变异算子.以兰州铁路局集装箱办理站为例进行了验证,结果表明:该算法不仅效率非常高,而且可以得到问题的多个最优...

| Abstract: | Empty container allocation problem was analyzed,according to railway transportation characteristic,and a genetic algorithm was designed to solve the kind of problem in the thesis.We employ integer matrix encoding.Crossover operation makes use of integer arithmetic for a linear combination of a pair of parents.The adjustment was also made in order to get feasible solution.Mutation operation adjusts transpotation quantity in rectangle circuit.At last the algorithm was tested by the true data of Lanzhou Railwa... |
