All values provided by experts in the original comparison matrix have been retained except the inconsistent elements and . Furthermore, the proposed method does not violate the scale [1, 9], needs fewer computations than Xu and Wei’ method and Cao’s et al method, and also preserve more original comparison information than these two methods. Compare with Saaty’s method, the proposed method is based on only the original comparison matrix A instead of the ratio of priorities. Any of the known methods, such as EM, DLSM, WLSM, LLSM/GMS, and GPM, could be applied to derive the priority vectors for the revised reciprocal comparison matrix by the proposed method and the same inconsistent entries will always be identified. Furthermore, the proposed method can also show the modification direction and provide the optimal values.
