The establishment and adjustment of the judgment matrix is very important in Analytic Hierarchy Process(AHP)algorithm. The paper establishes judgment matrix using the three-scale method after improving Satty's 1 to 9 scaling method. Considering the reciprocal matrix necessary and sufficient conditions,the paper proposes the adjustment method when judgment matrix is inconsistent to improve the consistency of judgment matrix and reduce the amount of computation.When dealing with the load balancing of Web clus...
