On Inconsistency of a Pairwise Comparison Matrix

Analytical hierarchy process is a method of solving a multiple attribute decision makiing.this method is based on the pairwise comparisons between the alternatives. these comparisons form a matrix named pairwise comparison matrix or judgment matrix theweights of mentioned alternatives will be determined from this mentioned above matrix.in the case of consistency of the judgment the cited weights are reliable and trusty. onthe other handif the consistency of the judgment matrix is not acceptable the resultsucient level of trust in this case it is requested that the decision maker revise the judgment in this paper we propose a method to approximate a consistent judgment matrixfrom an inconsistent one without the revision of the judgments. this method is based ondecreasing the eects of the mistakes made by the decision maker.
