摘要
本文对层次分析法中权的最小平方排序方法进行改进,提出一种新的改进的加权最小二乘排序方法,并从理论上进行证明。文章最后通过一个实例将两种排序方法与特征根排序方法进行对比分析,结果表明,改进的加权最小二乘排序方法可导出与特征向量排序方法相同的排序结果,克服了权的最小平方排序方法与特征向量排序方法排序结果不一致的缺点。
This paper makes improvements on the weighted least-square priority method of AHP. A new improved priority method is presented and proved theoretically.Finally, the above two methods are compared with the eigenvector priority method through an example. Results show that the improved priority method can get the same priority as the eigenvector priority method and avoid the unreasonable priority of the old method.
