Mathematical model is a scientific or engineering model constructed by using mathematical logic method and mathematical language. The history of mathematical models can be traced back to the time when humans began to use numbers. With the application of numbers, various mathematical models are constantly established to solve various practical problems.

A mathematical model can be established to establish an optimal scheme for daily activities such as college students' comprehensive quality evaluation, teachers' work performance evaluation, and visiting friends and purchasing. The establishment of mathematical model is a necessary bridge to communicate the relationship between practical problems and mathematical tools.

At present, there is no uniform and accurate definition of mathematical model, because different angles can have different definitions. But we can give the following definition. Mathematical model is an abstract and simplified structure of a part of the real world, which has special uses.

Specifically, a mathematical model is an equation or inequality established by mathematical symbols such as letters and numbers for a certain purpose, and it is a mathematical structural expression that describes the characteristics of objective things and their internal relations, such as charts, images, block diagrams, etc.

Mathematical model is a new discipline developed in recent years, and it is a science that combines mathematical theory with practical problems. It reduces practical problems to corresponding mathematical problems, and on this basis, it uses mathematical concepts, methods and theories to conduct in-depth analysis and research, thus depicting practical problems from a qualitative or quantitative perspective and providing accurate data or reliable guidance for solving practical problems.
