Model$-$Based Software Development

An engineer should design an adaptive cruise control system for a vehicle using modelbased software development. She has already designed and analyzed the controller by simulation but not tested the controller under real environment conditions yet. The vehicle with sensors and actuators is available. The electronic control unit $($i$.$e$.$ target system$)$ which will finally be used is not known yet.

$($a$)$ Draw the V$-$model of model$-$based software development!

$($b$)$ At which stage in the V$-$model is the engineer currently?

$($c$)$ Which concept of model$-$based software development should the engineer use next? Justify your answer!

$($d$)$ State one advantage and one disadvantage of model$-$based software development!
