基于突变级数法的绿色铁路客站施工评价模型

Evaluation model of railway station construction based on catastrophe progression method

针对我国绿色铁路客站施工尚未形成一套完整的绿色客站施工评价体系的情况,提出突变级数法,探讨适合我国国情的绿色铁路客站施工管理评价方法,为规范我国绿色铁路客站施工管理评价提供理论支撑。对绿色铁路客站施工管理评价目标进行多层次分解,然后将底层评价因素进行无量纲化、归一化处理,运用不同突变模型的归一公式进行计算,得到突变级数值,给出评价等级。实例研究表明:突变级数法法可避免人为确定权重的主观性,且计算简单、可靠性高,评价结果更趋于实际,可作为绿色铁路客站施工管理评价的理论参考。

At present, there is no integrated evaluation system for construction of green railway station. According to the actual situation in China,this paper discussed the establishment of a set of evaluation criteria for green construction of railway station catastrophe progression method, which has a strong guiding role to regulate green railway station construction. Firstly, the multi-layer evaluation objects were analyzed in this method, and standard quantization of bottom evaluation indexes was performed. Then, the ultimate catastrophe function was obtained through quantitative computation by the normalization formula of different catastrophe models. Lastly, the comprehensive evaluation of alternative was realized. The result of an evaluation example indicates that the presented method can not only avoid the subjective quantification of assessment indexes, but also be easy to perform and obtain high reliability, which improved the practicability of the catastrophe progression method. Theresearch conclusion can provide a theoretical reference for green construction evaluation of high-speed railway station.
