Mathematical modeling is to establish a mathematical model according to actual problems, solve the mathematical model, and then solve the actual problems according to the results. When it is necessary to analyze and study a practical problem from a quantitative point of view, people should understand the information of the object, make simplified assumptions and analyze the inherent laws on the basis of in-depth investigation and study.

Using mathematical symbols and languages to build mathematical models. Over the past half century, with the rapid development of computer technology, the application of mathematics has not only played an increasingly important role in engineering technology, natural science and other fields, but also penetrated into new fields such as economy, management, 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. Mathematical model is a kind of simulation, which is an abstract and concise description of the essential attributes of practical topics with mathematical symbols, mathematical formulas, programs and graphics. It may explain some objective phenomena or predict the future development law.

Or it can provide an optimal strategy or a better strategy in a sense for controlling the development of a phenomenon. Mathematical model is not a direct copy of real problems, and its establishment often requires people to observe and analyze real problems in depth and carefully.
