What Is a System Simulation?

System simulation is based on the purpose of system analysis, based on the analysis of the nature of the elements of the system and their relationships, to establish a simulation model that can describe the structure or behavior of the system and has a certain logical or quantitative relationship This is done experimentally or quantitatively to get all the information you need for the right decision. ^[1]

Simulation or translation (Simulation), broadly based on

(1) It is a kind of seeking for system problems

(1) The process of simulation is also a process of experiments, and it is also a process of systematically collecting and accumulating information. Especially for some complex random problems, the application

The basic method of system simulation is to establish the structural model and quantitative analysis model of the system, and convert it into a simulation model suitable for programming on a computer, and then carry out simulation experiments on the model.

Because the mathematical models of continuous systems and discrete (event) systems are very different, system simulation methods are basically divided into two categories, namely continuous system simulation methods and discrete system simulation methods.

On the basis of the above two basic methods, there are some special and effective methods for system (especially socioeconomic and management system) simulation, such as system dynamics method, Monte Carlo method, etc.

The system dynamics method is to study the dynamic relationship between system structure, function, and behavior by establishing a system dynamic model (flow diagram, etc.) and using DYNAMO simulation language to implement a simulation experiment on a real system on a computer. ^[2]
