Abstract: In real life,the attribute values of many information systems are based on intuitionistic fuzzy numbers because of different needs.In view of this phenomenon,an intuitionistic fuzzy order relation was established on the basis of the weighted score function and an inconsistent intuitionistic fuzzy ordered decision information system with preference measure was proposed.Furthermore,the partial consistent function was introduced into the complex system,and the method of solving partially consistent reduction was studied by the partially consistent discernibility matrix.Finally,the feasibility and effectiveness of the proposed method were verified by a case.
