When we finish the whole mathematical modeling process, we should summarize the work and write a paper. Writing a paper on mathematical modeling is similar to completing the answer sheet when participating in mathematical modeling for college students in many ways. In fact, the mathematical modeling competition also includes the test of students' writing ability, so the writing of papers is a very important issue.

First of all, we should make clear the writing purpose of the paper. Mathematical modeling is usually put forward by some departments according to actual needs, and perhaps those departments have provided financial support. At this time, the paper has the purpose of reporting to specific departments, but even in other cases, it is necessary to make a comprehensive and systematic summary of the whole process of modeling, so that relevant technicians (marking staff during the competition) can believe the rationality of the model assumptions and understand the applicability of the mathematical methods used in the process of model establishment, thus affirming the data and conclusions of the model. Of course, a good paper is based on the scientific nature of the mathematical model established by the author. Secondly, we should pay attention to the organization of the paper.
