Mathematical modeling is a method to solve various practical problems by establishing mathematical models. There is no fixed format and standard for mathematical modeling, and there is no clear method. There are generally six steps: 1, clear the problem; 2. Reasonable assumptions; 3. Establish a model; 4. Solve the model; 5. Analysis and inspection;

6. Model interpretation. ? The problems of mathematical modeling are usually practical problems in various fields, and these problems are often vague, so it is difficult to directly find the key points and clearly put forward what methods to use. Therefore, the primary task of establishing the model is to identify the problem.
