Healthy Operator 4.0: A Human Cyber–Physical System Architecture for Smart Workplaces

Abstract

Recent advances in technology have empowered the widespread application of cyber–physical systems in manufacturing and fostered the Industry 4.0 paradigm. In the factories of the future, it is possible that all items, including operators, will be equipped with integrated communication and data processing capabilities. Operators can become part of the smart manufacturing systems, and this fosters a paradigm shift from independent automated and human activities to human–cyber–physical systems (HCPSs). In this context, a Healthy Operator 4.0 (HO4.0) concept was proposed, based on a systemic view of the Industrial Internet of Things (IIoT) and wearable technology. For the implementation of this relatively new concept, we constructed a unified architecture to support the integration of different enabling technologies. We designed an implementation model to facilitate the practical application of this concept in industry. The main enabling technologies of the model are introduced afterward. In addition, a prototype system was developed, and relevant experiments were conducted to demonstrate the feasibility of the proposed system architecture and the implementation framework, as well as some of the derived benefits.

Nuclear Power Plants With Artificial Intelligence in Industry 4.0 Era: Top-Level Design and Current Applications—A Systemic Review

“…In this part, we propose the top-level design of future NPPs as Nuclear Power Plant Human-Cyber-Physical System (NPPHCPS) based on the concept of Human-Cyber-Physical System (HCPS) [67]and Healthy Operator 4.0 (HO4.0) [68] which were both proposed for intelligent manufacturing .…”

“…HO4.0 represents Healthy Operator 4.0, which focuses on enhancing operators' physical and cognitive capabilities through further automation. The concept of HO4.0 is put forward by Sun et al [68] based on the system viewpoint of the industrial Internet of things (IIoT) and wearable technology and the fact that the network physical system is widely used in the manufacturing industry, and the operator will also become a part of the intelligent manufacturing system with the continuous development of information technology. Its four-layer architecture includes Smart Connection Layer, Integration & Communication Layer, Modeling Layer, and Cognitive Layer.…”

“…(1) Ensure the health and safety of operators and improve work efficiency. It can not only provide real-time health risk information, such as risk alarm but also simulate the future behavior of operators; Inferring and predicting their behavior evolution in the medium and long term can reduce operators' cognitive and physical workload and increase operators' happiness, such as occupational safety and job satisfaction [68]. (2) Improve the safe operation level of the nuclear power system.…”

“…By learning from the daily activities and parameters of operators, we can draw inferences about their longterm development from their digital twins. Moreover, the agent-based modeling method is used to model the participants, environment, rules, and mechanisms in the specific application demonstration field and build their model bases; Combined with the development status of various application fields, the scene database is constructed based on real-time monitoring data [68].…”
