摘    要:为科学、合理地安排铁路线路建设,提高铁路建设资金的使用效率,考虑新建线路的碳排放、投资回报率和对铁路网的作用,采用主观赋权的层次分析法和客观赋权的熵值法,引入主观系数,确定各决策指标的权重,建立铁路线路建设时序决策模型;考虑铁路建设对国民经济的重大影响,铁路线路建设时序应该符合国家经济政策发展趋势以及地方的需求,提出政策系数,改进铁路线路建设时序决策模型。实例分析结果验证改进后决策模型的正确性。

Abstract: In order to conduct the railway line construction scientifically and reasonably, and improve the efficiency of railway line construction fund, carbon emissions and the effect on the rail network of newly-built lines were referred, the analytic hierarchy process (AHP) of subjective empower and the entropy value method of objective empower were used, the subjective factor and the weight of each index were introduced, and the railway line construction schedule model was established. Considering the significant effect of the railway construction on the national economy, and that railway line construction schedule should conform to the development trend of national economic policies and local requirements, the policy factors to improve the railway line construction schedule model were established. The case analysis results verify the model’s correctness.
