【摘要】 权重是模糊综合评判中的关键指标体系,直接影响模糊综合评判结果的准确性。本文将熵权多目标决策原理应用到模糊综合评判方法中,直接利用隶属度矩阵给评价指标的墒权赋值,避免人为主观因素的影响,使评判结果更加科学、公正。通过对延安市宝塔区某滑坡稳定性模糊综合评判,结果表明,基于墒权法模糊综合评判结果较准确,可信度较高,方法可行,对于同类工程地质稳定性评价有一定的参考价值。更多还原

【Abstract】 The weight is the key index to the Fuzzy Comprehensive Evaluation,and it can have direct effects on the accuracy of the evaluation.In this article the theory of multiple objective decisions making with entropy weight method is applied to the Fuzzy Comprehensive Evaluation,and the entropy weight values can be provided by membership matrix without artificial subjective factors,so the results is scientifical and more accurate.A certain landslide in Baota district of Yan’an city in Shaanxi province is analysed with the fuzzy comprehensive evaluation method. The results indicate that the fuzzy comprehensive evaluation for the stability of landslide with entropy-weight method has more accurate results and more reliability,and the method is feasible,which has some referenced values for the evaluation on the engineering geology stability.更多还原
