Simulation Modelling - scheduling and verification

Which of the following is a comparison of the conceptual model with the real system?

• Validation

• Verification

What is the primary goal of verification in system development?

• To ensure the simulation model is built correctly according to specifications from conceptual model

• To compare the simulation model with real-world requirements

Bob has three projects that he needs to work on. The projects are in the following order: A (due date - 7th March), B (due date - 16th Feb), C (due date - 10th March). If you use the earliest due date dispatching rule, what is the correct sequence of projects?

• A, B, C

• C, A, B

• B, A, C

Consider a simulation model of a small factory in which parts arrive for machining and are then inspected. The model runs for 160 hours. The simulation reaches steady-state at 40 hours and we do not want to collect results this period. What is the warm-up time?

• 160 hours

• 40 hours

• 200 hours

Take a look at the picture of the simulation model. What can be done to reduce the parts in the queue?

• Increase the queue capacity

• Add more machining stations

• Add more inspection stations
