Using Metrics For The Assessment Of Human Interaction With Worker Assistance Systems
Factories often include worker assistance systems to support assembly through cognitive guidance, connected tools and sensors. The benefits are improvements in productivity and quality. While the measurement and display of productivity and quality is widely spread, the underlying human interaction with worker assistance systems is not yet established to be assessed in key performance indicators. Those metrics are necessary to measure the level of human-centered design of assembly stations and worker assistance systems. The metrics are meant to yield detailed insights on the information perception of workers and the resulting work activities. Besides the discovery of needs for reconfiguration of worker assistance systems and assembly stations, the metrics can also be used as a basis for comparison to quantify differences between multiple setups.
This paper investigates metrics for the assessment of human-centered assembly station design and worker assistance systems. Therefore, multiple categories of metrics on human-technology-interaction are derived from literature and contextualized for worker assistance systems. For validation, selected metrics are implemented at an industrial-grade assembly station for an electric motor replica in a learning factory. The findings in the validation allow the assessment of the information perception and the work activities regarding material picking, handling and ergonomics
Digital Assistance Systems to Implement Machine Learning in Manufacturing: A Systematic Review
Implementing machine learning technologies in manufacturing environment relies heavily on human expertise in terms of domain and machine learning knowledge. Yet, the required machine learning knowledge is often not available in manufacturing companies. A possible solution to overcome this competence gap and let domain experts with limited machine learning programming skills build viable applications are digital assistance systems that support the implementation. At the present, there is no comprehensive overview over corresponding assistance systems. Thus, within this study a systematic literature review based on the PRISMA-P process was conducted. Twenty-nine papers were identified and analyzed in depth regarding machine learning use case, required resources and research outlook. Six key findings as well as requirements for future developments are derived from the investigation. As such, the existing assistance systems basically focus on technical aspects whereas the integration of the users as well as validation in industrial environments lack behind. Future assistance systems should put more emphasis on the users and integrate them both in development and validation
Modelle und Strategien zur Einführung des Computer Integrated Manufacturing (CIM) – Ein Literaturüberblick
Deutsch:
Im Rahmen der seit einigen Jahren verstärkten Aktivitäten von Wissenschaft und Wirtschaft im Bereich der digital vernetzten Produktion kann eine Auseinandersetzung mit den Erfahrungen und Erkenntnissen von Computer Integrated Manufacturing (CIM) hilfreich sein. Hierfür werden in diesem Beitrag 37 CIM-Modelle kurz beschrieben, weiterführende Literaturhinweise angegeben und die Visualisierungen der Grundstrukturen abgebildet. Darüber hinaus werden Literaturhinweise zu einigen Planungs- und Umsetzungsstrategien im Kontext CIM gegeben sowie der Stand verfügbarer CIM-Reifegradmodelle dargestellt.
English:
Within the framework of the activities of science and business in the area of digitally networked production, which has been intensified for a number of years, an examination of the experiences and knowledge of Computer Integrated Manufacturing (CIM) can be helpful. For this purpose, 37 CIM models are briefly described in this article, additional literature references are given and the visualisations of the basic structures are depicted. In addition, there are references to some planning and implementation strategies in the CIM context, as well as the status of available CIM maturity models
A guide to develop competency-oriented Lean Learning Factories systematically
In the last decade, various lean learning factories were established in industry and academia around the globe. They are used for experience-based training, education, and practice-oriented research. Learning factories provide a reality-conform production environment as a learning environment. Processes and technologies of the learning factory are based on real industrial sites. Learning factories doesn't only contain single workplaces or machines, but changeable multilink value added chains. Trainees can test and discover lean approaches in this environment and experience the holistic range of technological, organizational, and social issues linked to the approaches. The main goal of learning factories is an effective competency development, i.e. the development of the participants’ ability (including motivational and emotional aspects) to master complex, unfamiliar situations. In order to reach this goal a systematic approach for the competency-oriented design of learning factory courses and systems is needed. Such a competency-oriented approach for the development of lean learning factories is presented, integrating the conceptual design levels ‘learning factory’, ‘teaching module’, and ‘learning situation’. This approach addresses issues of intuitively designed learning factories and therefore enables an effective development of intended competencies. As a result lean learning factories including teaching modules and learning situations meeting the requirements of industry can be designed with a reduced effort and an increased success in the transfer to real problem situations. Among others, a case study of designing a learning module in the environment of the process learning factory CiP in the field of "Lean Quality" is presented in detail
