本文针对铁路分段建设问题,首先从有两个区段的新建铁路入手,探讨了铁路分段建设多目标动态规划模型的阶段划分方法,然后提出了有n个区段新建铁路的分段建设多目标动态规划模型的阶段划分途径,并进一步分析了模型目标值的确定问题。该模型可以动态地解决新建铁路的分段投资、分段运营决策问题,可以科学地确定出各区段的建设顺序。文中最后给出的计算举例说明了这一方法的科学性和实用价值。
In this paper, starting with the newly built railway with two sections, this paper discusses the stage division method of multi-objective dynamic programming model of railway section construction, and then proposes the section construction of n-section new railway Multi-objective dynamic programming model of the stages of the division, and further analysis of the model to determine the value of the problem. The model can dynamically solve the segmented investment and segment operation decision-making problems of new railway and can scientifically determine the construction sequence of each section. The calculation example given finally shows the scientific and practical value of this method.
