模糊线性规划在列车运行调整中的应用

Application of Fuzzy Linear Programming in Train Operation Adjustment

利用模糊集理论来处理列车运行调整过程中涉及的不确定因素,通过合理的权重系数来表示不同约束条件和目标函数的相对重要程度,在Werners方法的基础上提出一种基于加法算子带权重系数的对称型模糊线性规划。将该模型用于沪宁段列车运行晚点调整的优化问题,计算得到了优于Wern-ers方法的结果。

A new approach of fuzzy linear programming is proposed for solving the train operation adjustment problem. A characteristic feature of this approach is that the relative importance of objective function and constraints are represented by different weight coefficients. As an extension of the Werners＇ method, it has shown promising results when applied in the operation adjustment expermients of the Hu-Ning high-speed railway section.
