I. Introduction
The concept of industry 4.0 was proposed during the German Hanover Fair in 2011 [1]. According to the final report of the Industrie 4.0 Working Group, industry 4.0 is defined as the technical integration of Cyber-Physical Systems (CPS) into manufacturing and logistics and the use of the Internet of Things (IoT) and Services in industrial processes [2]. The economic potential of industry 4.0 for Germany is estimated to be 267 billion euros of which the electronics industry is expected to contribute 23 billion euros [3]. Since 2011 academic research is strongly focusing on the different technologies behind the concept of industry 4.0. However, in order to realize the estimated economic potential, these technologies need to be implemented in concrete use cases that provide value to manufacturers.
