模糊可拓层次分析法研究

Study on extension fuzzy AHP method

为了科学地定量评价社会系统，并使评价方法更符合实际，有必要对层次分析法进行改进．首先在使用专家打分法过程中，不要求专家给出一个确定的值，可以在一个范围内，依据1-9标度法对评价对象打分；然后，用可拓学方法进行关联度分析和模式识别，确定某个评价对象一个确定的可拓分析值；再在建立模糊评价矩阵的基础上，利用层次分析法进行最后的评价．应用根据这一思路建立的可拓模糊层次分析模型对中国辽宁省的3个城市的交通文化系统进行了综合评价．

To evaluate the society system scientifically and make the assessment method accord with fact, it is necessary to ameliorate the Analytic Hierarchy Process （AHP） method. Firstly, the experts don＇ t need to evaluate the objects by identified values, that is, they can mark the objects in a range by 1 -9 sign method. Secondly, an extension analytical value is identified for an evaluated object by the extension method to analyze association degree and make pattern recognition. Finally, based on the established fuzzy evaluation matrix, the final evaluation is done by AHP. And the extension fuzzy AHP model is established, which is used to synthetically assess the Liaoning China. communication culture system of three cities in Liaoning China.
