基于经济效益的高速铁路列车开行方案评价及调整

Evaluation and adjustment of high-speed railway train line plan based on economic benefits

高速铁路列车开行方案优劣直接影响高速铁路的市场经济效益,而列车开行方案评价是优化开行方案的基础。为优化运输组织、提高经济效益,从营运能力、盈利能力和服务能力3个方面构建高速铁路列车开行方案评价指标体系,引入后退法思想筛选指标,构建基于决策偏好的超效率DEA评价模型确定列车开行方案经济效益评分,利用投影原理构建基于投入要素限制的调整优化模型,优化调整DEA无效的列车开行方案。以京沪高速铁路为例,结果表明,该方法能较好地反映高速铁路列车开行方案资源利用和产出效率,能为高速铁路列车开行方案优化提供理论指导和决策依据。

The train line plan of high-speed railway directly affects the market economic benefits,and the evaluation of the train line plan is the basis of optimizing the train plan.In order to optimize the transportation organization and improve the economic benefit,the index system of high-speed railway train line plan was constructed from operation ability,profitability and service ability.The idea of backward method was introduced to screen the index to obtain the final index system.The super efficiency DEA evaluation model based on decision preference was built to determine the comprehensive economic benefit score.The projection principle was used to construct the adjustment optimization model based on input factor restriction to adjust the train plan with invalid DEA.Taking Beijing-Shanghai high-speed railway as an example,the results show that this method can better reflect the resource utilization and output efficiency,and provide theoretical guidance and decision-making basis for the optimization of train line plan.
