Bridging the Modeling Gap Across Transport, Tracking, and Kill-Chain

Today’s defense modeling and simulation landscape is fragmented — transport, tracking, and kill-chain domains each rely on incompatible formalisms, temporal models, and data representations, creating a structural integration gap that no single tool has been able to close. By adopting DEVS (Discrete Event System Specification) as a unifying formalism, organizations gain a mathematically rigorous composition theory that bridges these domains without forcing model homogenization. DEVS enables modular, port-based coupling so that transport kinematics, probabilistic sensor fusion, and decision-theoretic kill-chain logic can exchange events through a single event bus — while keeping each domain’s internal models independent and swappable at runtime. The result is hierarchical multi-resolution simulation, explicit dependency contracts between domains, formal verification of each component, and a clear path to cross-domain M&S accreditation — all within one composable framework.
