| 摘 要： | 研究了带时间限制的最小费用运输问题,在分析了运量与运输时间关系的基础上,把运输时间划分成与运量无关和与运量有关的两部分;进一步根据已知的运输时间与运量的函数关系,把带时间限制的最小费用运输问题转化为最小费用最大流问题,给出了求解该问题的方法,并通过实例进行了计算。

| Abstract: | The paper studies the minimum cost transport problem with time constraint,and,after analyzing the relationship between volume and time of transport,dichotomizes transport time into volume-related and volume-unrelated parts.Then in accord with known equational relationship between time and volume of transport,it converts the minimum cost transport problem with time constraint into a minimum cost maximum flow problem and presents the approach for its solution which is verified in an empirical study. |
