 If a systems modeling tool conforms to the XMI specification and includes the XMI representation of the UML Profile for SysML and the XMI representations of Model Libraries defined by SysML, the tool provides the import and export of both SysML diagrams and model data from one tool to another. XMI (XML Metadata Interchange) is a format specification that enables the interchange of objects and models through an XML formatted file. It is based on a metamodel that defines the abstract syntax and semantics of the model elements. By conforming to the XMI specification, a tool can serialize and deserialize SysML models in terms of XML elements and attributes. The tool can also include the XMI representation of the UML Profile for SysML, which defines the mapping of SysML concepts to UML concepts, and the XMI representations of Model Libraries defined by SysML, which provide predefined types and units for SysML models. This way, the tool can import and export both SysML diagrams and model data from one tool to another, ensuring consistency and interoperability.

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.

This is the most important consideration for selecting a tool to support the project because it gives the project the most flexibility. A built-in support for the method means that the tool has features and functions that are aligned with the SysML-based development method chosen by the project. This can include documentation, context-specific help, templates, wizards, etc. A built-in support for the method can help the project to follow the method more easily and consistently. A mechanism for user-defined extensions to the tool means that the tool allows users to customize or modify the tool according to their needs and preferences. This can include adding new features, changing existing features, creating new views or reports, etc. A mechanism for user-defined extensions to the tool can help the project to tailor the method over the life of the project and adapt to changing requirements or situations.

 Interaction-based exchange is a data exchange mechanism that uses an application programming interface (API) to access data in one tool and make it available in another tool. The API allows for direct communication and synchronization between the tools without requiring intermediate files or repositories. This approach can provide better performance and consistency than file-based or repository-based exchange.

The best way to ensure that a shared model has consistently-represented elements and diagrams is to use modeling conventions and standards. Modeling conventions and standards are rules and guidelines that define how the model elements and diagrams should be named, defined, structured, formatted and documented. Modeling conventions and standards can help improve the clarity, consistency and quality of the model and facilitate the communication and collaboration among the modelers and stakeholders. Implementation of standard libraries is a good way to ensure that a shared model has reusable and interoperable elements and diagrams, but it may not ensure their consistent representation. Packages that map one-for-one to components is a good way to ensure that a shared model has modular and traceableelements and diagrams, but it may not ensure their consistent representation. Domain stereotypes maintained in a configuration control system is a good way to ensure that a shared model has customized and controlled elements and diagrams, but it may not ensure their consistent representation.

To prevent any use of an unstereotyped block, the supervisor must mark the extending stereotype with the {strict} keyword. This keyword indicates that only elements with this stereotype can be created as instances of the extended metaclass. In this case, only blocks with the stereotype <<projectBlock>> can be created as instances of Block.

 A methodology is a set of principles, methods and practices that guide the execution of a project or activity. A systems engineering project always involves some kind of methodology, even if it is not explicitly defined or documented. Working spontaneously or randomly is also a form of methodology, although it may not be very effective or efficient. A systems engineering project cannot be conducted without applying any methodology at all.

The typical stakeholder views of a design are composed of both behavioral and structural diagrams, depending on the purpose and perspective of the view. Behavioral diagrams show how the system or part behaves or interacts in different scenarios or states, such as activity, state and sequence diagrams. Structural diagrams show how the system or part is composed of parts, ports, connectors and properties, such as block definition and internal block diagrams. Both types of diagrams are important to convey the functionality and architecture of the system or part to different stakeholders. Use case and requirements diagrams are not sufficient to populate the stakeholder views of a design, as they only capture the functional and non-functional aspects of the system or part.

 Coupling is a measure of how much a system element depends on other system elements. High coupling means that a change in one element affects many other elements, which makes the system harder to understand, maintain and reuse. Low coupling means that the system elements are more independent and modular, which improves the model quality. References: OMG-Certified Systems Modeling Professional - Model Builder – Advanced (OCUP2-ADV) Examination Guide Version 1.0, Section 4.1.2.2

This approach would be most effective from a MBSE perspective because it allows the system engineer to create a unified view of the design of the system and its components using SysML blocks and relationships. A block is an extension of the UML Class metaclass that can be used to model any system component with structure and behavior. A relationship is a connection between model elements that specifies some kind of dependency or association. By creating a SysML block structure representing the system and its components, the system engineer can capture the hierarchy, composition, classification, generalization, etc., of the system elements. By creating relationships between the blocks and the design models, such as MCAD, ECAD, or Spreadsheets, the system engineer can link the SysML model with the external models and provide traceability and consistency. The system engineer can also use the SysML model to generate a bill-of-materials for the system and its components, as well as to propagate changes made in one design model to another using allocation or synchronization mechanisms.
