Modeling and Simulation - Midterm Exam

What is a model in the context of simulation?

• A simplified representation of a system
• The actual system itself
• A random data generator
• A real-world experiment

Simulation is best described as:

• Running experiments on a real system
• Manipulating a mathematical model to imitate a real process
• A form of data collection
• An optimization algorithm

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

• Cost of real experimentation
• Safety concerns
• Exact analytical solution is easy to obtain
• Time constraints

The process of creating a model that represents a system is called:

• Simulation
• Modeling
• Sampling
• Validation

In a simulation study, input data are usually:

• Deterministic
• Random variables
• Constant
• Ignored

The first step in simulation modeling is:

• Data collection
• Problem definition
• Model validation
• Implementation

Which of the following is an advantage of simulation?

• Provides exact analytical results
• Handles complex systems
• Requires no data
• Always faster than real time

Which type of model uses equations to describe relationships?

• Physical model
• Mathematical model
• Iconic model
• Descriptive model

Which is NOT a component of a simulation model?

• Input variables
• Output variables
• Random number generator
• Database schema

Verification in simulation refers to:

• Ensuring the model represents the real system accurately
• Checking that the model is implemented correctly
• Comparing simulated results with theory
• Collecting data
