摘要(Abstract):

为了科学有效地比选铁路绿色选线方案,提出基于突变理论的铁路绿色选线方案优选的突变级数法。首先,对铁路绿色选线方案评价目标进行多层次分解,其次,将底层评价因素进行无量纲化处理、归一化处理,然后,运用不同突变模型的归一公式进行逐层计算,得到突变级数值,给出最优方案。实例研究表明,该方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。
To optimize green railway alignment selection,catastrophe progression method is proposed.Firstly,the multi-layer assessment objects are analyzed and then standard quantization and normalization of bottom assessment indexes are performed. Secondly,the ultimate catastrophe function is obtained through quantitative computation with the normalization formula of different catastrophe models. Thirdly,the comprehensive assessment of alternative is realized. The case study results show that the proposed method can avoid subjective quantification of assessment indexes and proves to be simple,reliable and effective and makes assessment results more practical.
