[2] Invited Talk by Dr. Saurabh Mittal:
Systems, Models and Simulation Architectures for Digital Twin Engineering
Abstract
Digital Twins are virtual models that are representative of, and often interacting with, their physical system counterparts. Methodologies needed to perform digital twin engineering (DTE) are adapted from various disciplines that include Software Engineering, Systems Engineering, Simulation Engineering, Network Engineering and the domain-specific Engineering and Physical Sciences.
DTE incorporates two fundamental aspects: the art of model abstraction for the digital twin that needs to be grounded in a specific discipline, and the underlying simulation/software systems infrastructure engineering that must support the constraints of digital twin performance.
This talk will share experiences with a Simulation, Experimentation, Analytics and Testing (SEAT) layered architecture framework and its application to cyber physical system (CPS) engineering, as applied to an Internet of Things (IoT) use case involving a digital network-enabled thermostat in a virtual home. We will demonstrate how models and systems are developed iteratively using agile systems engineering lifecycle and describe the architectural constructs for the persistent/on-demand hardware/software infrastructure for DTE.
