Study Notes
Introduction to MBSE
- MBSE is a comprehensive approach to Systems Engineering.
- It aims to manage the complexity of modern systems.
- It enables communication with stakeholders through models.
- It focuses on abstracting systems to simplify information for realization.
- MBSE is not a subdivision of Systems Engineering, it's a complete approach.
Evolution of MBSE
- Stages of MBSE evolution showcase the transition from document-based to model-centric engineering.
- Model consistency across views becomes crucial for a valid model.
Stage 1 - Document-Based Systems Engineering
- People: Basic competence in Systems Engineering.
- Process: May or may not be documented, but artifacts are predominantly text-based documents.
- Tools: Office-based tools like word processors, presentations, and spreadsheets.
Stage 2 - Document-Centric Systems Engineering
- People: Basic Systems Engineering competence, informal use of notations.
- Process: Still document-based, but with the initial use of notations to support text descriptions.
- Tools: Office-based tools with the addition of drawing packages for diagrams.
Stage 3 - Model- Enhanced Systems Engineering
- People: Notational competence, awareness of MBSE concepts.
- Process: Model emerges from documents, knowledge is split between the model and documents.
- Tools: Multiple tools used for modeling, representing the first proper application of MBSE.
Stage 4 - Model-Centric Systems Engineering
- People: Competence in MBSE and tool usage.
- Process: Almost fully MBSE-based with a framework including ontology and viewpoints, enforcing model consistency.
- Tools: A preferred tool is selected and used on real projects.
Stage 5 - MBSE
- People: Mastery of MBSE and its application.
- Process: Entirely model-based, mature framework and process set applied across projects.
- Tools: Tailored tools for automatic enforcement of the MBSE approach.
Models and Views
- Models consist of various views.
- Views are designed to address key questions:
- Who are the stakeholders?
- What information is needed?
- Why do stakeholders need the view?
Visualizing MBSE
- Diagrams are used to communicate model information.
- Various notations like SysML, UML, and others are employed.
- SysML is the preferred language for MBSE.
MBSE Framework
- A framework integrates viewpoints, ontology, and process set.
- It ensures consistent and structured model creation.
Tools and Compliance in MBSE
- Tools enforce notation and the framework.
- Compliance with best practices ensures quality.
- Common standards include ISO 15288 and ISO 42010.
The Spoken Language - The Systems Modeling Language (SysML)
- SysML is a general-purpose visual modeling language.
- SysML is based on UML (Unified Modeling Language).
- UML originated in the software engineering world.
- Prior to 1997 (the release of UML), numerous modeling notations and methodologies existed.
SysML Diagram Types
- Block Definition Diagram (BDD): Represents systems with blocks and relationships.
- Internal Block Diagram (IBD): Shows internal structure of a block and component interactions.
- Requirement Diagram (RD): Represents requirements and their decomposition.
- Parametric Diagram (PAR): Shows relationships between parameters and their mathematical relationships.
- Package Diagram (PD): Organizes a system into packages.
- Use Case Diagram (UC): Describes system behavior from a user's perspective.
- Sequence Diagram (SD): Shows interaction sequence between objects.
- State Machine Diagram (SSD): Represents the different states a system can be in.
Breakout Session
- Each team is assigned a different SysML diagram type and analyzes it.
- Teams should describe their assigned diagram, explain its purpose, and discuss its usage.
