This study addresses the challenges faced by traditional public management in universities due to advancements in educational information technology and the growing scale of higher education institutions. We propose a novel public management model for universities that leverages “Internet+” concepts, aiming to enhance internal audit systems and the competencies of management personnel. We use the AHP-TOPSIS fusion algorithm to assess the model’s impact on campus infrastructure and services management, selecting a central Chinese university for empirical Analysis. The findings reveal substantial improvements in campus road and landscape management, with weight values of 0.785 and 0.736, respectively, and a 74.67% satisfaction rate among students regarding cafeteria services. The success of this model demonstrates its effectiveness and introduces a forward-thinking approach to university management.
