Core Concepts Overview

Understanding the fundamental concepts of SELab.ai will help you work more effectively with the platform.

Architecture​

SELab.ai follows a layered architecture:

┌─────────────────────────────────┐
│     User Interface Layer        │
├─────────────────────────────────┤
│   Modeling & Analysis Engine    │
├─────────────────────────────────┤
│   Knowledge Base & AI Agents    │
├─────────────────────────────────┤
│      Data Persistence Layer     │
└─────────────────────────────────┘

User Interface Layer​

  • Web-based and desktop applications
  • Real-time collaboration features
  • Responsive design for all devices

Modeling Engine​

  • SysML V2 compliant
  • Multi-language support (DoDAF, UAF, etc.)
  • Constraint validation and verification

AI Layer​

  • Automated design generation
  • Intelligent recommendations
  • Pattern recognition and reuse

Data Layer​

  • Version control for models
  • Cloud-based storage
  • Export/import capabilities

Key Components​

1. Projects​

A project is the top-level container for your work. It includes:

  • Models and diagrams
  • Requirements
  • Documents
  • Team members and permissions

2. Models​

Models represent your system using formal modeling languages:

  • Structural Models: Define system components and relationships
  • Behavioral Models: Describe system behavior and interactions
  • Parametric Models: Capture constraints and equations

3. Requirements​

Requirements define what your system must do:

  • Functional requirements
  • Non-functional requirements
  • Constraints
  • Traceability links to models

4. Diagrams​

Visual representations of your models:

  • Block Definition Diagrams (BDD)
  • Internal Block Diagrams (IBD)
  • Sequence Diagrams
  • State Machine Diagrams
  • Activity Diagrams

5. Documents​

Generated artifacts based on your models:

  • Requirements specifications
  • Design documents
  • Test plans
  • Interface control documents

Modeling Languages​

SysML V2​

The primary modeling language, providing:

  • Precise semantics
  • Executable models
  • Analysis capabilities

DoDAF​

Department of Defense Architecture Framework:

  • Operational views
  • System views
  • Technical standards

UAF​

Unified Architecture Framework:

  • Strategic views
  • Operational views
  • Service views

Workflows​

SELab.ai supports various development workflows:

Waterfall​

Traditional sequential development:

  1. Requirements → 2. Design → 3. Implementation → 4. Testing

Agile​

Iterative development with sprints:

  • Continuous refinement
  • Regular feedback
  • Incremental delivery

V-Model​

Verification and validation focused:

  • Requirements ↔ Acceptance Testing
  • Design ↔ Integration Testing
  • Implementation ↔ Unit Testing

Data Management​

Version Control​

  • Automatic versioning of all changes
  • Branch and merge support
  • Change history and audit trail

Collaboration​

  • Real-time multi-user editing
  • Comments and annotations
  • Review and approval workflows

Import/Export​

Supported formats:

  • SysML/UML (XMI)
  • Excel/CSV
  • PDF/Word
  • JSON/XML
