Functional and Logical System Architectur
Systems engineering requires more than isolated diagrams. The Functional and Logical viewpoints in PREEvision translate abstract requirements into a structured, executable design. Define exactly what your system does and how it is organized before committing to physical hardware or software.
Beyond Generic Modeling Languages
Generic modeling languages often leave gaps between disciplines. PREEvision enhances standard SysML by embedding your diagrams directly into a unified data model. Every function and logical component connects seamlessly to your overarching requirements and downstream physical implementations. You eliminate tool silos, prevent data loss, and maintain an unbroken thread of traceability across your entire engineering organization.
Rigorous Architectural Control
- Seamless Integration: Map stakeholder requirements directly to functional networks and logical system structures.
- Enhanced SysML: Utilize standard notations – like sequence and activity diagrams – backed by a robust, domain-specific data model.
- Early Validation: Verify functional behavior and logical dependencies long before physical prototypes exist.
- Manageable Complexity: Break down highly networked, multidisciplinary systems into clear, understandable architectures.
Visualize Behavior and Structure With SysML
PREEvision provides the standard Systems Modeling Language (SysML) notations you need to design your Functional and Logical architectures with absolute precision:
- Functional Viewpoint (Behavior Diagrams):
Define dynamic system behavior and interactions using Use Case, Activity, State Machine, and Sequence Diagrams. - Logical Viewpoint (Structure Diagrams):
Define static architectures and component relationships using Block Definition, Logical Architecture, and Class Diagrams.
RFLP-Centric Development With PREEvision
Experience functional and logical modeling in action. These tutorials from the PREEvision MBSE Trial show you exactly how to define system behavior and structure your logical architecture within the RFLP framework.
We offer PREEvision as a hosted trial, giving you the opportunity to explore its capabilities hands-on. Interact directly with our demo model and experiment with MBSE in a real-world context.
