OMG-OCSMP-MBA400 Exam - Topic 1 Question 45 Discussion

Choose the correct answer.A control unit aboard a ship sends commands to a remote-controlled submarine. which in turn sends messages to the ship after completing each major stage of its overall mission. For each distinct stage, the ship orders the submarine to perform a different set of operations. Completing any given stage takes a widely variable amount of timeWhy it is appropriate to use the MARTE profile to model this system with SysML?
D) The control unit must order the submarine's operations in real time, which the MARTE profile makes it possible to model in SysML.
A) The control unit is an embedded system, which the MARTE profile makes it possible to model in SysML
B) The stage transitions of the mission equate to a logical dock, a temporal construct that MARTE brings to SysML
C) The stage transitions of the mission equate to a chronometric clock a temporal construct that MARTE brings to SysML

A control unit aboard a ship sends commands to a remote-controlled submarine. which in turn sends messages to the ship after completing each major stage of its overall mission. For each distinct stage, the ship orders the submarine to perform a different set of operations. Completing any given stage takes a widely variable amount of time

Why it is appropriate to use the MARTE profile to model this system with SysML?

Show Suggested Answer Hide Answer
Suggested Answer: D

It is appropriate to use the MARTE profile to model this system with SysML because the control unit must order the submarine's operations in real time, which the MARTE profile makes it possible to model in SysML. MARTE is a UML profile that provides concepts and annotations for modeling and analyzing real-time and embedded systems. It supports modeling time-related properties and constraints, such as deadlines, periods, durations, clocks, etc., as well as resource-related properties and constraints, such as memory, CPU, power, etc. By using MARTE, one can capture the real-time requirements and behavior of the system and perform schedulability and performance analysis.

Wait, is MARTE really necessary for this? Seems overkill.

I think option D makes the most sense here.

The control unit is definitely an embedded system!

I feel like option C might be relevant too, but I can't recall how a chronometric clock fits into the overall mission stages.

I’m leaning towards option D because real-time operations seem crucial for the control unit, but I’m unsure if MARTE is the right fit for that.

I remember practicing a question about temporal constructs in MARTE, so option B sounds familiar, but I’m not confident about the terminology used.

I think option A makes sense since the control unit is an embedded system, but I'm not entirely sure how MARTE applies specifically.
