Simulation is the imitation of the operation of a real-world process or system over time.
Contents
Model
The act of simulating something first requires that a model be developed. This model represents the key characteristics or behaviors/functions of the selected physical or abstract system or process.
Simulation represents time
The model represents the system itself, whereas the simulation represents the operation of the system over time.
Uses
Simulation is used in many contexts, including simulation of technology for:
- Performance optimization
- Safety engineering
- Testing
- Training
- Education
- Video games
Often, computer experiments are used to study simulation models.
Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning.
Simulation can be used to show the eventual real effects of alternative conditions and courses of action.
In place of real systems
Simulation is also used when the real system cannot be engaged, because:
- It may not be accessible
- It may be dangerous or unacceptable to engage
- It is being designed but not yet built
- It may simply not exist
Key issues
Key issues in simulation include:
- Acquisition of valid source information about the relevant selection of key characteristics and behaviors
- The use of simplifying approximations and assumptions within the simulation
- Fidelity and validity of the simulation outcomes
