Abstract
Errors or inaccuracy always occurs when we use the Analytic Hierarchy Process to aid decision making. This paper shows the errors can be divided into two parts. One is called System Error and another is called Judgment Error. System Error is caused by the judgment ratio of pairwise compare matrix which must be taken from set of {1/9, 1/8, ..., 1,2,..., 9}. The Judgment Error is caused by human wrong judgment. The computational results in this paper demonstrate that the System Error may cause the confusable priority of the alternatives and a proposed method which increase the ratio accuracy can clear the priority of the alternatives.
