Taking the construction of higher education quality assurance as the research objective, this paper designs the framework of higher education quality assurance platform containing seven modules: quality planning, teaching process, quality monitoring, efficient data, quality evaluation, basic data and system management. Based on the hierarchical analysis method, the assignment steps and methods of evaluation system indicators are detailed. K-means mean algorithm is adopted as a distribution analysis tool for the indicator scoring data. Under the theoretical framework of the above method, a higher education evaluation system containing 19 indicators is proposed based on the five teaching quality criteria, namely, the guiding ideology of running a school, the management of the teaching process, the teaching conditions, the learning support service system, and the educational and teaching effects. The validity of the index system is verified by calculating the fuzzy evaluation matrix and extracting the common factor. Applying the higher education quality evaluation index system to assess the teaching quality of University X, it gets a perfect score close to 5.00 on the guiding ideology of running a school, and performs poorly on the teaching conditions with only 2.97. The study points out that the platform of higher education quality assurance should be constructed from the outside to the inside by means of digital technology, by means of rationally adjusting the disciplinary settings, and by means of supervising the teaching process.
