Definition
Digital Twin Enterprise Architecture Framework™ (DTEAF™): The DTEAF is a reference Enterprise Architecture Framework (EAF) for architecting, designing, building, testing, and integrating Digital Twins (virtual Simulations-of-Simulations) that are indistinguishable from their Physical Twin (physical Systems-of-Systems) counterparts. The architecture infrastructure of DTEAF is the 6D System M-Model™ Enterprise Architecture Framework for Agile MBSE™, which has been customized to support the following core Digital Twin technologies, which are listed as related technology pairs: Massive Mathematical & Dynamic ModSim; Artificial Intelligence (AI) & Machine Learning (ML); 3D CAD & 3D Printing; and Virtual Reality (VR) & Augmented Reality (AR). The DTEAF is designed to be highly scalable, simulatable, and customizable.
DTEAF is derived from 25+ years experience designing and implementing recursively scalable and simulatable Enterprise Architecture Frameworks for Model-Driven Development (MDD) and Agile Model-Based Systems Engineering (Agile MBSE) applications. Since both the 6D System M-Model reference EAF and the DTEAF are specified using recursive architecture and design patterns using the OMG SysML™ architecture modeling language standard, they can be implemented and customized using popular architecture modeling tools that support that standard (e.g., MagicDraw™/Cameo™, Sparx Enterprise Architect™).

[Kobryn 2017] Digital Twin vs. Physical Twin Equivalency Test
"A reasonable litmus test for a Digital Twin is analogous to the Turing Test for AI. Let:
- ST = System Tester
- PS = Physical System
- PT = Physical Twin representation of PS
- DT = Digital Twin of PT
- V&V-TS = robust Verification & Validation Test Suite shared by PT and DT
If ST executes V&V-TS against both PT and DT, but cannot reliably distinguish DT from PT with probability greater than 80%, then DT is a bona fide Digital Twin of PT:
P(ST correctly distinguishes DT from PT | V&V-TS) <= 0.80— Cris Kobryn, Founder & CTO, PivotPoint Technology Corp. (2017)
