The cloud model is a model that mutually transforms the qualitative concept described in linguistic terms and the uncertainty in its representations using numerical values. Cloud model theory integrates the fuzziness and randomness of evaluation subjects and adopts an improved backward cloud algorithm to convert a qualitative concept into a quantitative value of an evaluation index such that the practical situations of each evaluation index can be described. Unlike traditional algorithms, this method does not use single numerical values alone for expression only but can also reflect the practical development trends of each index comprehensively and ideally. Thus, the theoretical model is of practical significance in evaluating the degree of satisfaction with network courses.
