ModeliHub: A Web-based, Federated Analytics Platform for Modelica-centric, Model-based Systems Engineering

This paper introduces ModeliHub, a Web-based, federated analytics platform designed specifically for model-based systems engineering with Modelica. ModeliHub's key innovation lies in its Modelica-centric, hub-and-spoke federation architecture that provides systems engineers with a Modelica-based, unified system model of repositories containing heterogeneous engineering artifacts. From this unified system model, ModeliHub's Virtual Twin engine provides a real-time, interactive simulation environment for deploying Modelica simulation models that represent digital twins of the virtual prototype of the system under development at a particular iteration of the iterative systems engineering life cycle. The implementation of ModeliHub is centered around its extensible, Modelica compiler frontend developed in Isomorphic TypeScript that can run seamlessly across browser, desktop and server environments. This architecture aims to strike a balance between rigor and agility, enabling seamless integration and analysis across various engineering domains.
