Modeling and Simlation

Which of the following best defines a model?

• The exact copy of a real system
• A simplified representation of a real system
• A random approximation of a system
• A simulation software
• Pluto

A physical model is best described as:

• A mathematical equation
• A tangible, scaled-down prototype
• A computer algorithm
• A probability distribution

Which of the following is a mathematical model?

• A clay model of the solar system
• A flowchart showing a business process
• A population growth equation
• A car prototype tested in a wind tunnel

A conceptual model is usually represented by:

• Equations
• Diagrams and frameworks
• Tangible replicas
• Random numbers

Which type of model includes randomness?

• Deterministic
• Probabilistic
• Static
• Conceptual

A dynamic model:

• Represents a system at one point in time
• Ignores changes over time
• Evolves and changes with time
• Is always deterministic

Which of the following is an example of a discrete model?

• Temperature change in a metal rod
• Water flow in a pipe
• Customer arrivals in a bank queue
• Growth of a tree

Which of the following is NOT a reason for using models?

• To simplify complex systems
• To reduce cost and risk
• To represent reality exactly
• To predict outcomes

Simulation is best described as:

• Building the model
• Experimenting with the model over time
• Collecting real-world data only
• Running static equations without change

Which is a real-world example of simulation?

• A bar chart of company sales
• A pilot training on a flight simulator
• A blueprint of a factory
• A physical scale model of a ship
