Model-Based Systems Engineering Quiz

_________ is the primary objective of Model-Based Systems Engineering (MBSE).

• To replace traditional documentation with graphical models.

• To automate software development processes.

• To focus solely on hardware design.

• To eliminate the need for system testing.

What happens if an ECU detects an abnormal engine condition while driving?

• It activates the windshield wipers.

• It sends a warning signal to the airbags.

• It triggers a check engine light and may limit engine performance.

• It adjusts the seat positions automatically.

Which phase of the System Life Cycle involves defining system requirements and objectives?

• Verification and Validation phase.

• Concept Development phase.

• Operations and Maintenance phase.

• Decommissioning phase.

During which phase of the System Life Cycle is the detailed design of system components typically performed?

• System Integration and Testing phase.

• Concept Development phase.

• Operations and Maintenance phase.

• Detailed Design and Development phase.

Which phase of the System Life Cycle focuses on deploying the system into its operational environment?

• Concept Development phase.

• System Integration and Testing phase.

• Operations and Maintenance phase.

• Verification and Validation phase.

How does the Systems Engineering Process (SEP) contribute to problem-solving?

• By avoiding stakeholder involvement until the final stages.

• By focusing only on hardware solutions.

• By applying a comprehensive and systematic approach.

• By delegating tasks to independent teams.

You are modeling a thermal system in Simscape. You connect a physical signal directly to a Simulink block without a PS-S Converter. What is the most likely result?

• The simulation will run, but the results may be inaccurate.

• The model will automatically add a PS-S converter.

• An error will occur due to incompatible data types.

• The signal will be interpreted as a temperature input.

You're building a hydraulic model using Simscape Fluids. The Solver Configuration block is missing. The simulation throws errors about 'missing solver configuration.' What is the thinking-level reason for this requirement?

• Simscape needs it to convert physical signals.

• Solver Configuration sets initial conditions and boundary assumptions for the physical network.

• It controls the units of physical quantities.

• It's required only for electrical models, not hydraulic ones.

In a Simulink model, you replace a group of blocks with a Subsystem. Which benefit are you most likely aiming for?

• Organize and simplify your model

• Convert discrete signals to continuous

• Improve simulation speed

• Change solver settings

A stateflow diagram of an automatic door system includes the following states: Closed, Opening, Open, and Closing. Transitions are triggered by events like PersonDetected and TimerElapsed. Which of the following best analyzes a potential design flaw if the transition from Opening to Open is missing?

• The door will never reach the Closed state again.

• The system will continuously stay in Opening, causing a functional hang.

• The event TimerElapsed will cause an unexpected transition to Closed.

• There will be no effect as stateflow diagrams are event-independent.
