Rank correlation analysis of formation of consistent judgment matrix

The analysis of rank correlation is proposed to form judgment matrix of which the consistency is very difficult to realize and the correction of inconsistency is unsatisfactory until now. The reason why the judgment matrix is inconsistent when forming it is analyzed. Discussing fully the information on matrix maker, the rank correlation of all indexes was found and set up so as to form the consistent judgment matrix of which the whole procedure should be done by the matrix maker himself. In such a way the procedure is clear, simple and highly exercisable. The example given shows its validity and the practicability.
