Industrie 4.0

Remanufacturing, previously characterized by manual and cost-intensive processes, is a critical step on the way to a resource-efficient circular economy. Industry and research agree that the introduction of Industry 4.0 technologies is the key to the development of automated and economical remanufacturing systems. Based on a systematic literature review, this paper is dedicated to the analysis of promising Industry 4.0 approaches with a focus on the overall process as well as the sub-processes of disassembly and inspection. The results suggest that there is a need for additional knowledge, experience and research in the development and real demonstration of the approaches and their transferability to broader application fields.

Smart Factory is the vision of a production environment in which manufacturing plants and logistics systems organize themselves as far as possible without human intervention. The article describes a project, at the start of which none of the participants created a relation to “Smart Factory” or “Industry 4.0”. Rather, the objective was to drastically reduce the current delivery time of 6-8 weeks. The result is a completely digitized business process from order creation, product development, design, manufacturing as well as processing for “batch size 1” with a reduction in lead time to less than 10 %.

The development of Industry 4.0 changes the role of humans in operations systems. In sociotechnical systems, there is ongoing interaction between humans and technology, impacting human life and work. However, human factors are broadly ignored in research on Industry 4.0 technologies and implementation. In this work, a process model is described that supports the evaluation of the impact of a technology implementation on human factors and performance indicators. This can avoid negative consequences for employees as well as phantom profits and can contribute to a successful digital transformation.

A successful digital transformation for attaining Industry 4.0, is a crucial success criterion for many companies today. The ongoing global COVID-19 pandemic has shown the need for digitalization in companies and has further accelerated this development. However, these times, companies are confronted with an uncertain order and profit situation. Thus, they need to allocate their investments purposefully. Evaluating the digital maturity by using a profound indicator system is therefore a sound basis for decision making. This paper develops such a sociotechnical KPI model along the dimensions “Strategy and Organizational Leadership”, “Digital Skills/Human Capital” as well as “Smart Process/Operations”. In the future, this model can be used for determining the digital maturity and thus, it can be applied for allocating digitalization investments.
