The coupling model [21] in this paper is a method to integrate the improved SEIR epidemic model with ham. Before starting to design a coupled model, it is necessary to determine whether the model is an appropriate method, which is a prerequisite for checking the expectations of a model. This section gives guidelines on when to apply the coupling model. However, these are not rules; instead, they describe the characteristics of the problem that are appropriate to use the coupled model approach. The key indexes to be considered in the application of the coupling model method are as follows:<br>
