Study Notes
When Simulation is the Appropriate Tool
- A plan can be visualized with animated simulation to understand complex systems.
- Simulation is necessary when experimenting with a real system is extremely costly and time-consuming, such as with satellite systems.
- Simulation helps in understanding the internal interactions of a complex system, which cannot be treated by other means.
When Simulation is Not Appropriate
- Simulation is not necessary when the problem can be solved by common sense.
- Simulation is not necessary when the problem can be solved analytically.
- Simulation is not necessary when it is easier to perform direct experiments.
- Simulation is not justified when the cost exceeds the savings or when resources or time are not available.
Advantages of Simulation
- Hypotheses about how or why certain phenomena occur can be tested for feasibility.
- Time can be compressed or expanded to allow for a speed-up or slow-down of the phenomena.
- Insight can be obtained about the interaction of variables.
- Insight can be obtained about the importance of variables to the performance of the system.
- New hardware designs, physical layouts, transportation systems, and so on can be tested easily.
Simulation Language and Software
- Simulation languages include MATLAB, Python, Java, C/C++, and others.
- Simulation software includes AnyLogic, Arena, AutoMod, ExtendSim, Flexsim, ProModel, SIMUL8, and others.
Goal of Modeling and Simulation
- A model can be used to investigate a wide variety of “what if” questions about real-world systems.
- Simulation can be used as an analysis tool for predicting the effect of changes.
- Simulation can be used as a design tool to predict the performance of new systems.
- It is better to do simulation before implementation.
