1. For which of these situations could simulation be helpful?
A. Testing new methods to automate paths for UAV (drones) flight
- Incorrect. D. All are correct
B. Preparing safety measures for a meltdown in a nuclear reactor
- Incorrect. D. All are correct
C. Trial runs of a new control system for a large factory
- Incorrect. D. All are correct
D. All of the above
- Correct. Simulation is a way to test processes and control systems before they are implemented. For some scenarios, such as safety systems, the simulation provides important validation.
2. What is the most widely used multivariable control strategy used in industry
A. Interacting PID loops
- Incorrect. Interacting PID control loops are one way to deal with multi-variate processes. However, it is not applicable to complex systems. Model Predictive Control is the most common multivariate control strategy.
B. Estimation
- Incorrect. Model Predictive Control
C. Model Predictive Control
- Correct.
D. Optimization
- Incorrect. Model Predictive Control
3. Which of the following falls under the category of process scheduling?
A. Organizing long term supply contracts for minimum cost
- Incorrect. This is supply chain management
B. Select a sequence of polymer grade transitions (changes every 1-3 days) to maximize profitability and meet customer demand
- Correct. This fits best in the category of process scheduling.
C. Sizing a reactor for max output rates
- Incorrect. This is process design
D. Real-time optimization of a plant based on hourly energy demand
- Incorrect. Real-time optimization is a steady-state process model with an economic objective function. It is commonly applied in chemical plants and refineries.
