In view of the present situation of the construction of digital campus in military academies, this paper combines the multilevel merit evaluation method and analytic hierarchy process (AHP), and makes a comprehensive evaluation on the maturity of the digital campus’s maturity in military academies. The multistage evaluation index system of the maturity of the digital campus’s maturity in military colleges is set up, the correlation function is established, the correlation degree and the correlation degree are calculated, the merit value of the evaluation index system at all levels is calculated. The maturity of the construction of the digital campus’s maturity in military colleges is synthetically evaluated, and computer programming is realized with Matlab. The example shows that the method provides a new way for the comprehensive evaluation of the digital campus’s maturity in military colleges. It also provides an important reference for the construction and development of the digital campus’s maturity in military colleges. It also lays a theoretical foundation for the development of the research on the digital campus maturity evaluation software.
