【摘要】 层次分析法已广泛用于群组决策中 .在群组决策中 ,每个决策者的决策水平是不相同的 ,因而每个决策者提供的信息质量也是高低有别的 ,因此应区别对待每个决策者提供的信息 .为此可构造一个过滤函数以充分利用高质量的信息而过滤掉低质量的信息 ,以改进对数最小二乘法 ,从而提高决策精度更多还原

【Abstract】 The Analytic Hierarchy Process(AHP) is widely used in group decision making. In group decision making, each decision maker has different decision capacity. So the quality of information given by each decision maker is also different. Thus the high and the low quality information should be treated differently. A constructed filter function can make full use of the high quality information and filter the low quality information to improve the decision accuracy.更多还原
