An improved AHP method in performance assessment

In order to reduce subjective errors in the traditional analytic hierarchy process (AHP), an improved AHP method integrated with orthogonal experimental design was presented in this paper. The new method combined both AHP and orthogonal design principles to make decisions, objectives in assessment system and values computed through mapping and satisfying function respectively as the corresponding factors, levels and results in orthogonal experimental design. With software SAS analysis, priorities on performance were to be ranked out accordingly. Application has showed that the method can improve the accuracy of AHP in performance assessment.
