3. What is Modeling and Simulation
?
Modeling:
The process of creating an abstract representation of a real-world system
.
Examples: Physical models, mathematical equations, diagrams
.
Simulation:
Using models to mimic the behavior of a system under specific conditions
.
Often run on computers for analysis and prediction
.
Key Idea:
Understand, analyze, and optimize real-world processes without directly
experimenting with them
.

4. Model: The abstraction or representation
.
System: The real-world entity being studied
.
Simulation: The computational process of running
the model
.
Input Data: Factors or parameters influencing the
system
.
Output Data: Results obtained from the
simulation
