Modeling Process for Simulation

This text describes the two main steps in the modeling process for simulation: creating a physical model and creating a mathematical model.

The physical model describes the system properties in a domain-specific form, while the mathematical model describes the system behavior in an abstract, system-independent representation.

Questions

• What are the two main steps in the modeling process for simulation?
• What is the difference between a physical model and a mathematical model?
• What are some examples of physical and mathematical models?

Answers

• The two main steps in the modeling process for simulation are creating a physical model and creating a mathematical model.
• A physical model describes the system properties in a domain-specific form, while a mathematical model describes the system behavior in an abstract, system-independent representation.
• Some examples of physical models include a mechanical system with masses and lengths, an electrical system with resistances and inductances, and a hydraulic system with chambers and valves. Some examples of mathematical models include differential equations, difference equations, and stochastic models.
