Satisfactory Consistency of Interval Number Comparison Matrix and Order-sorting Method

The consistency of interval number comparison matrix and order-sorting method were studied in this paper.The method used to saticfactory consistency matrix was proposed and it was tesitified that this method can be applid to the consistency of interval number comparison matrix.An optimizded model was developed in light of interval number comparison matrix which has consistency or satifactory consistency.Decision makers can solve the order-sorting vector of inernal number based on their own requirement on the consistency.Finnaly,the validity and practicality of the proposed methods were validated by arithmetical examples.
