The judgment matrix is the core of Analytic Hierarchy Process(AHP),playing a significant role in multi-factor comprehensive evaluation decisions.However,The existing teaching on judgment matrix overlooks the issue of how to reconstruct it if the consistency test fails,making it difficult for students to form systematic cognition,which in turn affects the practical appli-cation.The article systematically sorts out the concepts,construction,properties,testing,and adjustment of judgment matrix based on the logic of student learning and mastery.Through the preparation of a"supplier comprehensive evaluation"case,some data that violates the properties of consistent matrix are specially set up to enable students to experience the principles of constructing a judgment matrix,the steps of testing,and thought process behind adjustments.This deepens their understanding of the construction and testing points of judgment matrix,enabling them to proficiently apply judgment matrix to solve multi factor comprehensive decision-making problems.
