基于组合赋权法与欧几里德测度的公路飞机跑道选址优化

为解决公路飞机跑道选址方案优选问题,通过深入探讨和完善公路飞机跑道选址的评价指标,综合考虑适用、技术、经济和环保4个方面的要求,建立了公路飞机跑道选址的评价指标体系。结合熵值客观赋权法和改进层次分析主观赋权法,分别确定各评价指标权重初值,运用线性加权组合法将两者加以组合最终确定评价指标的权重值。进而提出以欧几里德距离为测度,比较各方案距离理想点的相对接近度,建立公路飞机跑道选址的多指标决策优化模型,对公路飞机跑道备选方案进行优选。结合公路飞机跑道选址实例,验证了公路飞机跑道选址的多指标决策优化模型的有效性和实用性。

The Optimization of Highway Runway Locating Based on A Combination Weighting Method and Euclid Distance

In order to solve the problem of the optimization of highway runway locating, by the way of investigating and consummating the targets of the highway runway locating, the paper has synthetically considered the requirements in four aspects of usability, technicality, economy and environmental protection to establish the system of evaluating targets for the highway runway locating. Each initial target weights are determined respectively based on the entropy method and the improved AHP method in a combination weighting method, by using the method of composing linear weighting all the target weights are ascertained finally. And then the measuring degree based on the Euclid distance for comparing the opposite closing degrees of all schemes is at a distance from perfect point, then the model of optimizing multiple target decision is established for selecting the best highway runway locating spared schemes. In combination with the living example of highway runway locating, the model of optimizing multiple target decision is tested effectively and practically.
