Digital Twin as a Service (DTaaS) in Industry 4.0: An Architecture Reference Model

Shohin Aheleroff et al.

Summary: Recent findings show that Digital Twin can provide services to multiple stakeholders, but a sophisticated reference architecture, suitable technologies, and a proper business model are needed. Most studies in the field focus on manufacturing, while empirical research on the relationship between Digital Twin and mass individualization is lacking. The study aims to identify suitable Industry 4.0 technologies and a comprehensive reference architecture model for challenging Digital Twin applications, indicating a significant relationship between Digital Twin capabilities as a service and mass individualization.

Sensor-Fault Detection, Isolation and Accommodation for Digital Twins via Modular Data-Driven Architecture

Hossein Darvishi et al.

Summary: This article introduces a machine-learning-based sensor validation architecture that uses neural network estimators and a classifier to detect and isolate faulty sensors for reliable digital twins. Results show that the proposed architecture performs well under different real-world datasets and synthetically-generated faults.

Digital Moka: Small-Scale Condition Monitoring in Process Engineering

Siddanth N. Bairampalli et al.

Summary: The study proposes a data-driven condition-monitoring system for a moka pot aiming at anomaly detection in the coffee-preparation process. By describing the data-acquisition system and the comprehensive dataset generation process, supervised and unsupervised machine learning algorithms are trained and tested to detect anomalies in the process and demonstrate the relevance of the considered framework.
