With the development of society, the application of mathematics not only plays an increasingly important role in engineering technology, natural science and other fields, but also penetrates into new fields such as economy, finance, biology, medicine, environment, geology, population and transportation with unprecedented breadth and depth. The so-called mathematical technology has become an important part of modern high technology.

The social demand for mathematics is not only the demand for mathematicians and talents who specialize in mathematical research, but also the demand for a large number of talents who are engaged in practical work in various departments, are good at using mathematical knowledge and mathematical thinking methods to solve a large number of practical problems they face every day, and obtain economic and social benefits. To analyze a complex practical problem, find out the relationship or law that can be described by mathematical language, and turn this practical problem into a mathematical problem, this problem is called a mathematical model. The process of establishing mathematical model is called mathematical modeling.
