针对列车起讫站设置中存在的模糊性与不确定性的问题,提出了结合模糊理论与规划理论确定列车起讫站的方法.以客运量、动车布局、路网地位以及社会属性最大为目标函数,以直达列车的最低客流需求、路网中的起讫站需求量为弹性约束,建立了模糊线性规划模型,采用了最大隶属度原则将模糊线性规划模型转化为一般线性规划模型的方法.最后以京沪高铁为案例进行了演算,实验结果证明方法的可行性与有效性.
Aiming at the fuzziness and uncertainty existing in the starting and ending station setting of train, a method combining fuzzy theory and planning theory to determine the starting and ending points of train is put forward. Taking passenger volume, moving vehicle layout, road network status and social attribute as the maximum objective function, Based on the minimum passenger demand of direct trains and the demand of freight terminals in the road network as the elastic constraint, a fuzzy linear programming model is established and the method of maximum membership degree is adopted to transform the fuzzy linear programming model into a general linear programming model.Finally, Shanghai high-speed rail for the case of the calculation, the experimental results show that the method is feasible and effective.
