Modeling is to build a model, which is an abstraction of things in order to understand them. It is an unambiguous written description of things.
The process of establishing a system model is also called modeling. Modeling is an important means and prerequisite for studying systems. Any process that uses models to describe the causal relationships or interrelationships of a system is modeling. Because the relationships described are different, the means and methods to achieve this process are also diverse. It can be modeled based on the mechanism of things by analyzing the movement rules of the system itself, or it can be modeled based on the existing knowledge and experience about the system through the processing of experiments or statistical data on the system. It is also possible to use several methods simultaneously.
