Building Blocks for Effective Modeling and Simulation of Systems Lifecycle using an End-to-End Model-Based Systems Engineering Framework

Abstract: Model-Based Systems Engineering (MBSE) has become a cornerstone of modern Systems Engineering (SE), enabling complex system design, analysis, and lifecycle management through formalized modeling methodologies. The Systems Modeling Language (SysML), as the de facto modeling standard, facilitates system representation but faces challenges in extensibility and adaptability across diverse domains. Existing MBSE frameworks often lack adaptability, constraining cross-domain application, hindering model reuse in industry applications in addition to lack of interfaces from the left side to the right side, resulting in various modelling gaps. This paper presents the conceptual design of an innovative “End-to-End Model-Based Systems Engineering (E2E-MBSE) Framework”, which addresses the persistent challenges in applying existing frameworks across the full system lifecycle. While MBSE is a promising alternative to traditional document-based approaches, its industrial application remains limited by the rigidity and domain-specific nature of current frameworks like DoDAF and TOGAF, which often fail to provide a cohesive approach from a system's inception to its disposal. The proposed E2E-MBSE Framework is architected as a next-generation solution, designed to overcome limitations in Industry 5.0 by offering a structured, model-centric approach to address core challenges like integrating human-centric design, empathic design, promoting sustainability, and enhancing resilience. The framework's core innovation is a modular, pattern-based approach that utilizes a library of reusable and scalable SysML packages. This structure provides a customizable "toolkit" rather than a rigid, monolithic standard, allowing practitioners and researchers to tailor the methodology to specific industry applications or domain-specific needs. Crucially, the framework is predicated on the foundational capabilities of a standalone architecture, with formal semantics and integrated APIs integration providing a technical backbone for developing a "Total System Model" (TSM) that serves as a single source of truth and evolves throughout the system's entire lifespan. This approach fundamentally redefines the relationship with the systems engineering Vee model. Instead of treating Verification and Validation (V&V) as discrete, late-stage activities on the right side of the V, the framework leverages real-time traceability capabilities to embed automated, continuous V&V directly within the modeling process. This creates a living "digital thread" that ensures traceability and consistency from requirements decomposition to system retirement, thereby significantly reducing project risk and enhancing operational efficiency. The research outlines the framework's architecture, its foundational principles, and its potential to revolutionize systems engineering by providing a flexible, scalable, and verifiable methodology for the complex systems of the future.
