Human-Robot Collaboration (HRC) has been proposed to add flexibility to traditional production systems. Digital Twin (DT) has been integrated with HRC for safety collaboration. The human behaviour model is an essential part of the DT. This paper aims to identify a research gap and possible solutions for human behaviour modelling in HRC. Therefore, this paper reviews human behaviour studies in HRC and ethology. The results show that the current HRC focuses on recognizing and monitoring human behaviour, but a deep analysis of human behaviour is still lacking. Computational Ethology (CE) has the potential to be applied to HRC to model human behaviour in a structured manner. Future work could focus on transferring knowledge from CE and designing robot control strategies for HRC safety

SiWear – Sichere Wearable-Systeme: Verwendung von Sicherheitsstandards im Entwurf von Wearable-Systemen am Beispiel der Benutzungsschnittstelle

IT-Sicherheit und Benutzbarkeit stehen häufig im Konflikt zueinander. Dies ist verbunden mit der weitgehenden Berücksichtigung von Aspekten der Benutzbarkeit bei gleichzeitig geringer Berücksichtigung der IT-Sicherheit in den Methoden zur Anforderungsanalyse. Im Projekt SiWear1 werden aus Einsatzszenarien die Sicherheitsanforderungen an Wearable-Systeme mit Hilfe des Sicherheitsstandards IT-Grundschutz abgeleitet. Dies ermöglicht eine frühzeitige Koordination von Anforderungen an die IT-Sicherheit sowie an die Benutzbarkeit und fördert somit die Vereinbarkeit von beiden

New Approaches to Through-life Asset Management in the Maritime Industry

AbstractEuropean shipbuilders are facing a strong, worldwide competition. Consequently they have to reinvent their market approach and expand their business. In the past, European shipbuilders were focused on cost reduction in the production process to offer new build vessels at a competitive price for decades. Changing the focus from the selling price optimisation to the life cycle cost optimisation could lead to competitive advantages and enable new business opportunities. This new approach of through-life asset management is investigated in the EU- funded project ThroughLife. The minimisation of a vessel’ life cycle costs could be realised by applying new and innovative technologies. However, new technologies are characterised by higher investment costs and uncertainty regarding functionality, reliability and reparability. As a result, the situation can be characterised as a dilemma for the new building yard the ship owner and the repair yard. Therefore the ThroughLife project focuses besides the development of new technologies on the identification, elaboration and application of new business model concepts to overcome this dilemma. One business model concept is the offer of a comprehensive service package against a fixed, time based fee, which would lead to an overall cost reduction due to economies of scale, lower administration costs and a risk reduction for the customer, which would support the market penetration of new technologies. Combining this business model approach with the technology of monitoring sensors increases the potential of this approach. The service provider could use the gathered information to schedule maintenance according to the actual condition of the vessel and identify potential mistreatment by the client. The customer would benefit from reduced, calculable costs and a lower risk level when applying new technologies. Further research contains lifecycle cost model calculations as well as real-life tests of the monitoring hardware in order to proof the concept

Industrial needs v. Engineering education curricula related to maintenance, production and quality in industry 4.0: A gap analysis case study in Tunisia and Morocco

International audienceTo improve the competitiveness of industry in Tunisia and Morocco, local authorities have adopted strategies to support industrial companies in modernizing their value-adding infrastructures. A sustained effort has been dedicated to encouraging industrial organizations to embrace the Industry 4.0 paradigm and technologies. Despite these continued efforts, engaging with Industry 4.0 is still difficult in countries like Tunisia and Morocco, particularly because industrial organizations struggle to find fresh graduates on the job market who are both skilled and qualified in Industry 4.0 operations. The contribution of this article is to initiate a process to better understand and assess the gap between industrial needs and academic offer with respect to Industry 4.0 skills and qualifications, considering the specificities of Tunisia and Morocco. We particularly focus on analyzing to what extent existing curricula in engineering education institutions satisfy or miss industrial needs and requirements in three core industrial business processes: maintenance, production, and quality (MPQ4.0). Therefore, a survey was conducted, from which a set of MPQ4.0 targeted skills and competencies were extracted and synthesized. Based on these skills and competencies, sample engineering education curricula are analyzed, gaps are identified, and recommendations for improvement are offered
