What is the purpose of the Domain Metamodel in UPDM?

  1. It defines the implementation metamodel.
  2. It defines the stakeholder requirements for the metamodel.
  3. It defines the mapping of UML to SysML and SOAML concepts
  4. It defines the melamodel concepts and relationships without any implementation

Answer(s): D

Explanation:

The purpose of the Domain Metamodel in UPDM is to define the metamodel concepts and relationships without any implementation. The Domain Metamodel captures the core concepts of DoDAF and MODAF in terms of entities, attributes, associations, and constraints. It does not specify how these concepts are implemented in UML, SysML, or any other language or tool. The Domain Metamodel serves as a requirements model for UPDM and provides traceability links between the domain concepts and the profile elements.

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?

  1. Import the Modelica time-based power usage results into SysML Then use SysML parametncs to calculate these scalar values, and compare them to the requirements
  2. ave 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.
  3. Use 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.
  4. Modelica 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

Answer(s): B

Explanation:

: 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.

Which OMG specifications does UPDM use at L1?

  1. UMLandSysML
  2. UML. SysML. and BPMN
  3. UML, SysML and MARTE
  4. UML, SysML and SOAML

Answer(s): A

Explanation:

The OMG specifications that UPDM uses at L1 are UML and SysML. L1 is the level of abstraction that defines the core concepts of UPDM without any implementation details. It is based on a Domain Metamodel that captures the common elements of DoDAF and MODAF. The Domain Metamodel is mapped to UML and SysML concepts using a Platform Independent Model (PIM). UML and SysML provide the basic metaclasses and diagrams that UPDM uses to represent architectures.

Choose the correct answer
What is the most significant deficiency impeding widespread use of SysML (without MARTE) in the real-time and embedded domain?

  1. a quantifiable notion of time and resources
  2. the terminology that is shared with the RT7E domain
  3. a means to distinguish embedded from non-embedded systems
  4. a means to quantify interactions between a system and its physical environment

Answer(s): A

Explanation:

The most significant deficiency impeding widespread use of SysML (without MARTE) in the real-time and embedded domain is a quantifiable notion of time and resources. SysML does not provide a standard way to model time-related properties or constraints, such as deadlines, periods, durations, clocks, etc., nor does it provide a standard way to model resource-related properties or constraints, such as memory, CPU, power, etc. These aspects are essential for real-time and embedded systems design and analysis. MARTE addresses this deficiency by providing concepts and annotations for modeling time and resources in a precise and quantitative way.
