How does SysML support systems engineering methodologies?

AThe generalization mechanism enables fitting of SysML to a methodology

BThe stereotype and profile mechanisms enable lilting of SysML to a methodology.

CSysML can only support a systems engineering methodology if it is used at the starting point of the project

DSysML does not support system engineering methodologies, as it is a language

Show Answer

Correct Answer: B

SysML is a general-purpose modeling language for systems engineering that can support various systems engineering methodologies. The stereotype and profile mechanisms are features of SysML that enable customizing and extending the language for a specific domain or purpose. By using stereotypes and profiles, SysML can be adapted to fit different methodologies and conventions without changing the core language semantics

Choose the correct answer.

Every night the computers at the data center of Bank F, located in Asia, must complete an analysis of the previous day s financial transaction dat

a. Bank F plans to merge with Bank G, located In South America, Increasing the volume of data by an order of magnitude. The design team charged with expanding the facilities to handle this additional load is modeling the data center with SysML using the MARTE profile

Which capability of MARTE will help determine whether the existing processors at the data center can handle the anticipated data increase?

Asupport for schedulability analysis

Bsupport for embedded systems such as the processors

Csupport for comparative analysis of processor architectures

Dsupport for modeling scheduled events that occur in different time zones

Show Answer

Correct Answer: A

The capability of MARTE that will help determine whether the existing processors at the data center can handle the anticipated data increase is support for schedulability analysis. Schedulability analysis is a technique for verifying that a set of tasks can be executed within given time constraints on a given platform. MARTE provides concepts and annotations for modeling tasks, resources, scheduling policies, deadlines, etc., and for performing schedulability analysis using various methods and tools.

Question No. 3

Choose the correct answer

Modehca solvers can produce large volumes of time-based results (such as time-based power usage), but requirements are often based on scalar values such as "maximum peak power" and 'average power usage".

Which of the following is generally the most effective way to verify such requirements?

AImport the Modelica time-based power usage results into SysML Then use SysML parametncs to calculate these scalar values, and compare them to the requirements

Bave the Modelica solver also compute these scalar values from its time-based power usage results Then import the resulting scalar values into SysML. and compare them to the requirements.

CUse the SysML4Modelica profile to transform the Modelica time-based power usage results into these scalar values Then import the resulting scalar values into SysML, and compare them to the requirements.

DModelica models can only produce time-based results and thus cannot support scalar results like these, which must either be calculated using a different tool or measured on physical prototypes Then enter the resulting scalar values into SysML, and compare them to the requirements

Show Answer

Correct Answer: B

: The most effective way to verify such requirements is to have the Modelica solver also compute these scalar values from its time-based power usage results. Then import the resulting scalar values into SysML, and compare them to the requirements. This way, the verification can be done at the same level of abstraction as the requirements, and avoid unnecessary transformations or calculations in SysML. Modelica solvers can provide various functions and operators to compute scalar values from time-based results, such as max, min, mean, integral, etc. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://modelica.org/documents/ModelicaSpec34.pdf

Choose the correct answer

A system engineer is designing an algorithm that governs the behavior of his system-of-interest He is using SysML for modeling system behavior and related allocations, and plans to auto-generate MATLAB code for algorithm execution and testing.

Which modeling approach should the engineer use?

Ause block constructs to represent the algorithm, and create use cases for each of the functions used in the algorithm

Buse activity constructs to represent the algorithm and its functions, and create actions to represent the use of functions in the algorithm

Cuse block constructs to represent the algorithm and its functions, and create part properties to represent the use of the functions in the algorithm

Duse activity constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm

Euse package constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm

FCode generation is outside the scope of SysML. so the system engineer should use UML

Show Answer

Correct Answer: B

This modeling approach should be used by the system engineer because it allows him to capture the behavior of his system-of-interest using SysML activities and actions. An activity is a behavior that specifies the coordination of actions. An action is a behavior that specifies a transformation or processing of data. By using activities and actions, the engineer can model the algorithm and its functions in terms of inputs, outputs, control flows, object flows, parameters, etc. He can also use allocations to relate the activities and actions to other model elements, such as blocks or requirements. This way, he can generate MATLAB code from his SysML model for execution and testing. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://sysml.org/tutorials/sysml-diagram-tutorial/

Question No. 5

Choose the correct answer

What is the forward temporal order of these development stages?

* needs analysis

* system acceptance

* system design * trade study

Aneeds analysis, system acceptance, system design, trade study

Bneeds analysis, system design, system acceptance, trade study

Cneeds analysis, system design, trade study, system acceptance

Dneeds analysis, trade study, system design, system acceptance

Etrade study, needs analysis, system design system acceptance

Show Answer

Correct Answer: C

The forward temporal order of these development stages is based on the typical sequence of activities in a system engineering process. Needs analysis is the first stage, where the problem and the stakeholder needs are defined. System design is the second stage, where the system architecture and requirements are developed. Trade study is the third stage, where alternative solutions are evaluated and compared based on various criteria. System acceptance is the final stage, where the system is verified, validated, and delivered to the customer.
