摘要
城际铁路运营方案评价是优化列车开行方案的重要手段之一,同时也是一个复杂的多指标综合评价问题。通过影响城际铁路列车开行方案主要因素的特征分析,建立起城际铁路开行方案指标体系。结合熵权系数法,利用理想点决策方法对城际铁路列车开行方案评价的可行性进行了分析。以沪宁城际铁路进行算例分析,结果表明:该评价模型具有计算过程简单、使用方便等特点,能够为列车开行方案优化问题提供新的思路和方法,从而为城际铁路运营组织提供技术支撑。
Evaluation of intercity railway operation plans is one of the important means to optimize train operation plan,it is also a complex problem in multi-index comprehensive evaluation problem.By analyzing the characteristics of the influence factors over intercity railway operation plans,an index system for intercity railway operation plans is established,the feasibility of the operation plans are analyzed by using the TOPSIS method in combination with Entropy-weight coefficient.By referring to Shanghai-Nanjing Intercity Railway,the analatic result shows that this model features simple calculation and convenient use,therefore may provide a new idea and method for the optimization of train operation,at the same time a technical support for the organization of intercity railway operation.
