摘要
The improvement of consistency index and the computation of priority values are studied by considering a vector of the comparison matrix in this paper.According to consistency weight index,the orderpreserving is discussed while a new vector is let into the comparison matrix,the methods of identification and revision for dissatisfaction vector are proposed,the computational formula for the revised vector are given so that the consistency weight index is optimum.the revision of the vector make the consistency of comparison matrix get much improvement and relate directly to the computation of priority vector.
