MBSE Architecture Decomposition and Design Synthesis
Decompose aerospace systems into functional and physical architectures using MBSE principles
What You Can Do
You can leverage Claude as an active design partner to decompose complex aerospace systems into coherent functional and physical architectures. Claude helps you systematically structure architectural hierarchies, validate decomposition logic, identify architectural gaps, challenge assumptions, and ensure internal consistency across your system model—enabling you to transition from document-centric to model-centric engineering while managing stakeholder complexity and architectural trade-offs.
Features
Systematically break down mission requirements into functional hierarchies with explicit requirements-to-function traceability
Develop allocation strategies that map functions to physical components while tracking design decisions and trade-offs
Generate package hierarchies, activity diagrams, block definitions, and flow specifications aligned with MBSE best practices
Identify gaps, inconsistencies, and circular dependencies in your decomposition through automated consistency checking
Compare competing architectural approaches across multiple criteria with structured trade study frameworks
Generate architecture definition documents (ADD) and design rationale that satisfy review criteria and governance requirements
Reverse-engineer poorly documented systems to reconstruct functional and physical architectures with traceability
Maintain and validate requirements-to-function-to-component allocation matrices across program phases
Example Output
Example 1: Functional Decomposition for Launch Vehicle
Mission: Deliver 5000 kg to LEO with 99% reliability
├── Vehicle Level Functions
│ ├── Propulsion (provide thrust for ascent)
│ ├── Guidance & Control (trajectory management)
│ ├── Structures (support loads, protect payload)
│ ├── Thermal Management (dissipate aerodynamic heating)
│ └── Payload Deployment (achieve target orbit)
│ ├── Separation Sequencing
│ ├── Velocity Adjustment
│ └── Attitude Stabilization
With allocation to subsystems: Propulsion → Engine + Feed System + Combustion Chamber; Guidance & Control → Flight Computer + Sensor Suite + Actuators.
Example 2: Architecture Trade Study
Series vs. Parallel RCS Configuration:
- Series: Reduces complexity (✓), increases response latency (✗), simplifies failure isolation (✓)
- Parallel: Faster response (✓), adds redundancy (✓), increases component count and cost (✗)
- Recommendation: Parallel for critical axes (pitch/yaw), Series for roll to balance cost/performance
Example 3: Consistency Gap Detection
Identified: Function "Thermal Dissipation" allocated to Thermal Management subsystem, but no physical radiator components defined in physical architecture. Trace back to requirements: 3 conflicting thermal margin targets across different burn phases. Resolution path suggested with stakeholder decisions needed.
