What is one of the most common reasons to utilize a SysML-Modehca integration?

to solve and analyze system advanced statistics models
to solve and analyze system dynamics models
to execute and analyze system activity models
to execute and analyze system state machine models

Answer(s): B

Explanation:

One of the most common reasons to utilize a SysML-Modelica integration is to solve and analyze system dynamics models. Modelica is a language for modeling complex physical systems based on equations and components. SysML is a language for modeling complex systems based on diagrams and textual notations. By integrating SysML and Modelica, system dynamics models can be defined in SysML using parametric diagrams and constraint blocks, and then solved and analyzed using Modelica tools and solvers.

Choose the correct answer
Which SysML diagram type is a modification of the UML Composite Structure diagram?

Parametric Diagram
Internal Block Diagram
Package Diagram
Block Definition Diagram

Answer(s): B

Explanation:

The SysML diagram type that is a modification of the UML Composite Structure diagram is the Internal Block Diagram (IBD). An IBD shows the internal structure of a block in terms of its parts, ports, connectors, and flows. It is similar to a UML Composite Structure diagram, but it adds some features specific to SysML, such as flow ports, flow specifications, item flows, nested connectors, etc.

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

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?
support for schedulability analysis
support for embedded systems such as the processors
support for comparative analysis of processor architectures
support for modeling scheduled events that occur in different time zones

Answer(s): A

Explanation:

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.

What is best practice to model a software application in a SysML model for a system?

block stereotyped with «software» represents the software application and its interfaces
A class stereotyped with «software» represents the software application and its interfaces
A component stereotyped with «software» represents the software application and its interfaces.
Software is typically not modeled in a system SysML model

Answer(s): A

Explanation:

The best practice to model a software application in a SysML model for a system is to use a block stereotyped with «software» to represent the software application and its interfaces. A block is a modular unit that encapsulates its structure and behavior and can be connected to other blocks via ports and connectors. A stereotype is an extension of an existing metaclass that adds additional information or semantics to a model element. By using a block stereotyped with «software», the software application can be modeled as a system component with its own properties, operations, ports, flows, etc., and can be allocated to hardware blocks or other software blocks.
