Analysis for an End-to-End MBSE Operational Architecture

Abstract

Model-Based Systems Engineering (MBSE) has shifted systems engineering toward digitally integrated architectures. However, methodological fragmentation among frameworks like UAF, ARCADIA, and MOFLT persists, characterized by ontological gaps and restricted interoperability. These constraints impede seamless End-to-End (E2E) lifecycle continuity across the SE “Vee” model. This research addresses these limitations by extending the E2E MBSE Framework, specifically formalizing the Operational Architecture (Ops-Arch) phase. Using a rigorous decomposition and reconstruction methodology, the Ops-Arch is synthesized by leveraging NASA standards and extracting high-fidelity artifacts from legacy frameworks. The development employs comparative analysis, reverse engineering of architectural patterns, and meta-model engineering to identify functional gaps and circularities. The resulting synthesis produces a comprehensive reference architecture that harmonizes disparate modeling blocks into a unified construct. This approach reduces practitioner cognitive load and facilitates the transition from abstract intent to concrete structural models. Key contributions include a cross-framework meta-model alignment, a semantic gap map, and a formalized E2E MBSE construct package anchored in a reference ontology. By bridging methodological heterogeneity, this framework ensures consistency in large-scale system design and enhances cross-disciplinary collaboration. This work demonstrates that dissimilar operational views can be systematically harmonized into a singular, precise architecture, improving both technical accuracy and human comprehension. Future research will evolve these constructs into executable architectures applied to a System of Interest (SoI) case study for integrated Verification and Validation (V&V).
