基于AHP-ELECTRE Ⅱ的公路“绿色”选线方案比选

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。

组合赋权简化ELECTRE法优选桥梁加固方案

为了从众多初步可行的桥梁加固方案中选择最佳方案,研究了组合赋权简化ELECTRE法在桥梁加固方案优选中的应用问题。采用非线性规划方法将层次分析法确定的主观权重和熵值法确定的客观权重进行组合,既考虑了决策者的主观意向,又在一定程度上避免了主观随意性。首次以简化ELECTRE法对备选方案进行综合比选,给出了方案间按优劣程度的完全排序。与经典排序方法ELECTREⅡ相比,简化ELECTRE法排序过程的复杂性和繁琐性,计算效率提高且更便于程序化操作。不再需要设定主观参数,避免了很多主观不确定性因素,提高了分析结果的鲁棒性。算例分析表明选出的最优加固方案与实际采用的相同,并且方案优劣顺序与ELECTREⅡ法、TOPSIS方法的结果一致。     

Intermodal route selection for cargo transportation from Korea to Central Asia by adopting Fuzzy Delphi and Fuzzy ELECTRE I methods

Due to the increase in trade from Korea to Central Asia, an efficient intermodal route for transporting cargo is important. Intermodal routing for long-distance transportation faces operational challenges, such as customs clearance, track gauge differences, and climate limitations. The initiative of the Silk Road Economic Belt recently proposed in China could improve trade and transport links in Asia and create an efficient transportation route that focuses on the railroad service provided in China. The objective of this study is to obtain an evaluation structure for intermodal routing and then find the route for transporting cargo from Korea to Central Asia under China’s Silk Road Economic Belt with integrated Fuzzy Delphi and Fuzzy (Elimination Et Choice Translating Reality (ELECTRE) I methods. After a sensitivity analysis is performed, development strategies and alternative routes are suggested. The results show that among the five principal factors, total cost is the most important factor for logistics companies when they select a transportation route, followed by reliability, transportation capability, total time, and security. Of the sub-factor weights, transportation costs and cooperation and emphasis among state organization are important. In the intermodal route results, route 3, Incheon to Qingdao to Horgos to Almaty, is preferred.     

城市轨道交通规划决策中的消去与选择转换法

在对消去与选择转换法(ELECTRE)的特点进行分析和研究的基础上,针对低劣度矩阵只反映比较方案个别指标劣势、方案排序过于复杂及主观参数难设定等问题,提出了能全面反映比较方案总体劣势的低劣度矩阵新定义;同时还提出了一种新的排序方法.
