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?

• A.  use activity constructs to represent the algorithm and its functions, and create actions to represent the use of functions in the algorithm
• B.  use activity constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm
• C.  use package constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm
• D.  use block constructs to represent the algorithm, and create use cases for each of the functions used in the algorithm
• E.  use block constructs to represent the algorithm and its functions, and create part properties to represent the use of the functions in the algorithm
• F.  Code generation is outside the scope of SysML. so the system engineer should use UML

A large company uses SysML to design energy systems, and plans to use a specialized proprietary analysis tool (X) for evaluating and comparing the cost, performance, and reliability of energy system alternatives The engineers at the company want to automatically create analysis models in X from design models in SysML.
The achieve this, they will use the following process:
(1) Specify the appropriate module in X10 be used for each block m the SysML design model.
(2) Write scripts that use these mappings to automatically create analysis models in X Which approach is most flexible when enabling this automation?

• A.  define a profile that contains a tag for each type of X in the tool, and assign the stereotype to the blocks in the design model
• B.  define a package that contains a note for each type of module in X. and anchor notes to the blocks in the design model
• C.  define a package that contains a block for each type of module m X (e g module_1 block) and create a dependency relationship from the module block to the blocks in the design model
• D.  define a profile that contains a stereotype with a tag that can store the name of the module in X. apply the stereotype to the blocks in the design model, and populate the tag
• E.  define a profile that contains a stereotype for each type of module m X. and assign the stereotype to the blocks in lite design model

What is the key distinction between SysML modeling and MOF modeling?

• A.  MOF models are used for domain-independent modeling SysML models are used for domain-specific modeling.
• B.  MOF models are intended to be strictly models of abstract entities SysML models represent real world entities and processes
• C.  MOF models are intended to be models of modeling constructs SysML models represent real world entities and processes.
• D.  They both have the same purpose except that MOF modeling is intended for specialized and advanced usage by systems architects

The lead systems engineer on a project has identified a set of Key Performance Parameters (KPPs) that need to be evaluated both on a periodic basis during development, and during acceptance for everydesign change.
Many of these KPPs are expressed In complex, interrelated differential equations The analysis team has identified appropriate numerical techniques for solving these equations and expressed them in a popular analysis tool.
The lead system modeler and methodologist must ensure that the architecture and design captured in the SysML system model are continuously and accurately reflected In the KPP calculations.
Which strategy is likely to be most successful in accomplishing this?

• A.  Work with the analysis team to partition the KPP evaluation model into manageable, reusable subroutines Develop constraint blocks within the SysML model to represent these subroutines, exposing their parameters. Use these new constraint blocks to build a parametric model that ties the KPP evaluation directly to system model element value properties. Leverage available bridging software to link this parametric model to the evaluation subroutines executing in the external analysis tool, and re-evaluate the KPPs on an as-needed basis
• B.  Use activity and/or state models to accurately model the flow of data to numerically solve the KPP evaluation equations Ensure that the analysis team validates these behavior models Bind each relevant value property within the system model to an activity parameter or state variable such that the KPP evaluation model accurately reflects how the KPPs are derived. Next, use code generation capability inherent in the SysML tool to generate and compile the KPP evaluation routines Recompile and run these routines as needed to update KPP estimates
• C.  List the parameters used to evaluate the KPPs in a spreadsheet file. Use the SysML modeling tool's inherent capability to link appropriate value properties to cells in this spreadsheet Task the analysis team with modifying their analysis routines to accept parameters as an input vector from this spreadsheet.
  Ensure that the spreadsheet is updated from the system model prior to each update of the KPP calculations
• D.  Task the analysis learn with recasting each of the KPP equations as constraint blocks and parametric models directly in SysML and linking the resulting parameters to value properties of current system model elements Keeping all information in the same model is the only way to guarantee the consistency the lead engineer has asked for

How should stereotypes be grouped to facilitate re-use in later projects?

• B.  in sub-models
• C.  in metamodels
• D.  in packages
