基于AHP-ELECTRE Ⅱ的公路“绿色”选线方案比选

Green Highway Alignment Selection Based on AHP and ELECTRE Ⅱ

公路建设对沿线自然环境有着重大影响,因此"绿色"选线过程中应充分考虑环境因素。利用层次分析法(AHP)建立层次分析模型并确定评价指标权重,然后利用消去与选择转换(ELECTRE Ⅱ)综合评价法,实现各路线方案的环境影响量化评价。通过实例,证明该方法可以较好应用于公路"绿色"选线方案比选。

The highway traffic has a complicated impact on the environment along highway line. As a result, the environmental factor must be considered in the course of highway alignment selection. Firstly, AHP was used to establish hierarchical structure mode and the weight of indexes are con- firmed. Then, ELECTRE Ⅱ was used to assess the alignment schemes . At the end of the paper, an actual example was used to verify that this method can be well applied to green highway alignment se- lection.
