| 摘 要： | 模糊综合评价法是一种建立在模糊数学基础上的地下水水质评价方法,在水质模糊综合评价中,权重占有极其重要的地位,它反映了各个指标在水质评价过程中所起到的作用,直接影响到模糊综合评价的结果。为了避免传统方法的不合理之处,本文提出AHP-熵权综合赋权法即结合主观赋权法(AHP法)和客观赋权法(熵权法)计算指标权重,此方法在充分利用专家的经验和知识的同时兼顾了各个数据的信息,有效地避免人为因素的影响,降低主观性和盲目性。并应用实例与不同赋权方法分析比较,证明该方法切实可靠。

| Abstract: | The method of fuzzy comprehensive evaluation is a kind of evaluation method of groundwater quality based on fuzzy mathematics.The weight in fuzzy comprehensive evaluation occupies a very important position, and reflects the importance of various indicators, directly affects evaluation results. In order to avoid unreasonable aspects of traditional method, this article introduced the comprehensive weight method based on AHP and entropy to calculate weight. This method fully thought the experience of experts and information of each data and effectively avoided the subjectivity and blindness.The evaluation results show that the comprehensive weight method based on AHP and entropy is practical and reliable. |
