摘　　要：在层次分析法中,提出了先排序再比较确定元素权重方法替代用判断矩阵确定元素权重的方法.此方法一定程度上减少了判断不一致性、降低了人工比较次数,更适用于涉及因素和对象较多的问题.实验结果表明该方法的有效性.In AHP, a method is proposed to determinate weight of elements by using first sort and then comparing instead of judgment matrix. This method reduces the unconsistency of judgements and the number of comparisons. AHP based on this method is more suitable for problems which contain many factors and objects. The experiment results show the method is effective.
