Verification and Validation in Simulations

What is the primary purpose of verification in discrete event simulation?

• To ensure the simulation model accurately represents the real system

• To ensure the conceptual model accurately represents the real system

• To ensure the simulation model operates as intended

• To ensure the simulation model is cost-effective

Which of the following is NOT a reason for neglecting verification and validation in simulations?

• Time and budget pressures

• Laziness

• Overconfidence

• Lack of software tools

What technique involves visually verifying the simulation's operation to detect errors?

• Conduct Model Code Reviews

• Check the Output for Reasonableness

• Watch the Animation for Correct Behavior

• Use the Trace and Debug Facilities

Which test is used to determine if sample data is drawn from a normally distributed population?

• Welch Test

• Paired-t Test

• Normality Test

• Sensitivity Analysis

What is the main difference between verification and validation?

• Verification checks the real system, validation checks the conceptual model

• Verification ensures the model is built right, validation ensures the right model is built

• Verification is done before validation

• Verification is more important than validation

What does the term 'face validity' refer to in the context of model validation?

• The model's ability to replicate historical data

• The model's logical consistency

• The model's appearance to knowledgeable individuals

• The model's sensitivity to input changes

Which of the following is a technique used in verification?

• Watching the Animation

• Conducting Degeneracy and Extreme Condition Tests

• Checking for Face Validity

• Conduct Model Code Reviews

What is the purpose of using WIP Templates in FlexSim?

• To view charts and statistics of the running model

• To calculate the average of time differences in each process

• To conduct normality tests

• To perform sensitivity analysis

Which of the following is a reason for conducting sensitivity analysis in model validation?

• To determine the effect of input changes on the model's behavior

• To compare the model with historical data

• To check for face validity

• To conduct model code reviews

What is the role of 'trace and debug facilities' in verification?

• To visually verify the simulation's operation

• To provide detailed textual feedback of the simulation process

• To compare the model with other valid models

• To conduct normality tests
