To Solve Weight Vector of Judgment Matrix by Method of the Least Squares

In this paper, computing method of solving weight vector of judgment matrix by means of the least squares principle and the Lagrange's multiplier method is derived. Maximal deviation ofweight vector which was obtained at critical value of judgment matrix compatibility criterion by meansof maximal eigenvalue and it's eigenvector method is demonstrated by means of some examples.
