Introduce two classic books, the first one is compiled by foreigners, which is easy to understand. The latter book is edited by Jiang Qiyuan (Jiang Qiyuan is currently the executive director of the Chinese Society of Industrial and Applied Mathematics, a member of the Professional Committee of Mathematical Modeling, and the secretary-general of the Organizing Committee of the National Mathematical Modeling Competition for College Students).

1, Mathematical Modeling (America), translated by Frank R Giordano Morris D Will William P Fox, Ye, Jiang Qiyuan, etc. Machinery industry press.

2. Editor-in-Chief of Mathematical Model: Jiang Qiyuan and Xie Jinxing Alfred Publishing House: Higher Education Press.

But if you want to do a good job in mathematical model, basic knowledge is the foundation, such as operations research, which was first published by Tsinghua University Publishing House, also known as the "Green Book". Mathematical statistics are also essential. There are many excellent books in this field. Just borrow one from the library. The second is to look at software tutorials, such as matlab, lingo, spss, eviews and so on.

These are the basic preparations for mathematical models, and a lot of knowledge needs to be learned in competitions. Learning how to learn quickly is actually the most important thing!
