Analytic Hierarchy Process (AHP) is a hierarchical weight decision analysis method. Finding the solution weight value from the consistency matrix is an important step in analytic hierarchy process. From the consistency matrix in analytic hierarchy process, several computing weights methods are analyzed. The derivation process of sum method and root method are given. According to the idea, three new methods are derived. The computation method and results are given through a numerical example. The three calculation methods can be used as a supplement to the weight calculation methods.
