A System‐of‐Systems Modeling, Simulation and Data Analytics Framework for Resilient Sustainment and Support Readiness Strategies

Abstract In today's strategic defense environment, the rapid deployment and sustainment of aircraft fleet operations are critical to maintaining mission readiness. These operations require the optimization of multiple factors, including mission intensity, equipment configuration and reliability, spare parts logistics, maintenance quality, and personnel availability. INCOSE “Vision 2035” emphasizes the growing need for system resilience in the face of increasing complexity and highlights the evolving role of systems engineering in addressing sustainment and operational challenges through a holistic life cycle perspective. This paper introduces a framework and case study leveraging System of Systems (SoS) modeling and simulation to enhance sustainment and support readiness for aircraft fleet operations. By integrating Model‐Based Systems Engineering (MBSE) with the Unified Architecture Framework (UAF), System Modeling Language (SysML), model execution, and stochastic simulations, the study demonstrates advanced “what‐if” analyses to optimize logistics flows across geographically dispersed partners. Additionally, the incorporation of real‐time data from logistics, maintenance and repair operations enhances virtual models, enabling efficient resource management and ensuring sustained mission readiness under diverse operational conditions.
