Some Notes on Pairwise comparison Matrices
Zhengxin Jiang, Wei Yixiang · ISAHP proceedings · 1988
The existence of a 6est approximation to the pairwise comparison matrix from the set of consistent Aatrioes is proved.At the same time, we can also prove that there are many best approximations.Then by diffeomorphism, we transform the primary nonlinear approximation into a linear one.Hence we get an approximate method to abtain the best approximation.Finally, we give a simple example.
