Introduction to simulation models

Simulation models refer to various models made by studying simulation objects. Such as the physical model of the simulated object or the mathematical model suitable for computational processing. The physical model is used for physical simulation, the mathematical model is used for mathematical simulation (computer simulation), and the combination of the two is used for semi-physical simulation. In mathematical simulation (computer simulation), the mathematical model of the system must be rewritten into a simulation model before the corresponding computer program can be written and run on the computer. The mathematical model is a first-order approximation model of the system, while the simulation model is a second-order approximation model.
