Digital Twin Roadshow for Medical Devices

Hassan Sartaj, Simula Research Laboratory, Oslo

Automated system-level testing of IoT healthcare applications necessitates a test infrastructure that can integrate multiple medical devices from various vendors. However, physical integration is laborious, costly, and impractical. To address this, we, in collaboration with Oslo City’s healthcare department, proposed a cost-effective solution: a model-based approach for creating digital twins (DTs) of medical dispensers. Our approach’s evaluation, using real-world medicine dispensers, demonstrated the high fidelity of the DTs. In the DT roadshow, we exhibit digital twins of medical dispensers built to support automated testing of healthcare IoT applications. Mainly, we will demonstrate a medicine dispenser and its DT operating side by side, both integrated with an IoT application. In this demonstration, we will run tests targeting various functionalities, such as medicine dispensing, to showcase the operating mechanism, fidelity, and synchronization of the DT in relation to its physical counterpart.

Digital Twin of a Milling Machine

Jingxi Zhang, ISW, University of Stuttgart

The pressentation is intended to contain a milling machine for a milling operation of a wood piece in a wood manufacturing. More precisely, it drills an engraving into a wood piece. This process can be stopped and continued during runtime. Next to it is a visual representation in a simluation environment (VirtuOS). These data are propergated via a digital twin. The connection between the digital twin and the milling machine is build on an OPC UA server. Since the transport and setup of the physical machine is difficult and costly, this presentation will contain a video, a dashboard to contol the digital twin and the simulation environment, where commands are shown as movements.

The Digital Vehicle File: a self-service DT system

Theresho Mogowane - BMW IT Hub South Africa

We will showcase our highly configurable digital twin platform. The digital twin system is based on a central data model that lives 100% in configuration. Featuring data warehousing and federation approaches, we provide access to integrated data through a version-less API based on a GraphQL inspired custom query language. The digital twin supports features such as lifecycle phases and statutes as first class citizens to handle the evolution if the digital twin’s state over its lifecycle.

The Digital Twin Demonstrator

Jakob Trauer, engineering methods AG

We show how a bidirectional information exchange can be implemented based on a model train showcase, which will be presented in a live demo. The :em AG Digital Twin Showcase highlights the value of Digital Twins for optimizing the operation of technical systems, improving sustainability, and increasing system availability. Using the Asset Administration Shell and the Bosch Semantic Stack, we present how live usage data can be used to automatically control the operation of the train and fill the digital product pass (DPP). For the exchange of operational data, we used MQTT and Rest API. Further, using neutral exchange formats - such as PLMXML or ReqIF - we also realized interoperability between common engineering tools, e.g. for product data management or requirements management. By implementing these interfaces, we show how interoperability enables the implementation of Digital Twins and Model-Based Engineering.
