Warehousing is a very labor- and cost-intensive task in many companies. Digitization and automation of manual warehouse processes can increase efficiency, reduce costs and relieve employees. Collaborative robots that share work tasks with employees are increasingly used in warehouses. However, the pure techno-centric use of such robots can negatively influence the acceptance of human-robot collaboration. Various influences such as fear of job loss, higher cognitive stress, expected extra effort, or concerns about injuries can hinder human-robot collaboration and negatively impact economic benefits. This paper presents possible barriers to the acceptance of collaborative robotics in warehouses and discusses recommended actions for human-centered, sustainable human-robot collaboration.

The introduction of new Industry 4.0 technologies is changing job characteristics in many manual industrial sectors, especially in production and logistics, through automation and digitization. Depending on the extent and degree of maturity, these changes are perceived differently by employees and can have both positive and negative effects on job satisfaction and motivation. This article uses the example of workplaces in in-house logistics to highlight how their characteristics change as a result of the introduction of Industry 4.0 technologies. It also presents a process model that can serve as a decision-making aid for companies to consider important implications for the successful transformation process and to pursue the human-centric design of manual, technically supported workplaces.

The use of LNG propulsion in ships has significant environmental benefits but also creates chal- lenges in handling. Due to safety regulations, the maintenance of the LNG ship systems requires a high degree of reliability and accuracy. Thus, this paper deals with the development and evaluation of an AR-assistance system. The system based on an Android smartphone enables users to access maintenance instructions and manuals and supports the work process step by step through context-sensitive virtualizations. Its evaluation was conducted as a combined quantitative and qualitative user study.

Due to the change of work in manufacturing caused by the introduction of Cyber-Physical systems, there is a need for adequate design principles for user interfaces between humans and machines. Within a research project, a method for the determination and evaluation of such design principles was developed. The method can be used to create a catalogue of rules regarding the successful integration of human factors into Cyber-Physical production systems.

It is against the background of Industrie 4.0 that profound knowledge of the principles and basics of manual work or efficient work design, respectively, gains particular importance. It will continue to be a fair and neutral reference basis for the design of productive and ergonomic work in the Smart Factory. By collecting both time-relevant and ergonomically relevant data, MTM-HWD® (Human Work Design) a new MTM (Methods-Time Measurement) building block system offers an unprecedented quality in describing and evaluating human work. It, thus, combines work method-oriented with ergonomic work design.

Companies are constantly exposed to radical change. One approach to addressing these challenges is changeable production systems. Changeable production systems can only be as adaptable as the human being who is working in them. An integrated view of the dimensions of human beings, technology and organization is essential in this context. The Institute of Industrial Management and Factory Systems has wide experience and competences in the field of research of adaptable production. This is supported by the lab area of the IBF, called IBF-Lab, which allows interdisciplinary research. Practical application is demonstrated using an example of a research project.

More and more virtual tools are used for issues of product ergonomics and human factors in production. This article describes the use of digital human models as virtual tools used in CAx systems, PLM systems and in the digital factory. An empirical study with users of these systems shows the benefits working with these systems and the problems, which have to be solved in the future. The main question, answered by the article, is: Will virtual ergonomic tools be used by experts in the future or will these tools become a standard for constructing engineers and production planners?
