  Production plants today are becoming more and more complicated through more
automation and networking. It is becoming more difficult for humans to
participate, due to higher speed and decreasing reaction time of these plants.
Tendencies to improve production systems with the help of cognitive systems can
be identified. The goal is to save resources and time. This mapping study gives
an insight into the domain, categorizes different approaches and estimates
their progress. Furthermore, it shows achieved optimizations and persisting
problems and barriers. These representations should make it easier in the
future to address concrete problems in this research field. Human-Machine
Interaction and Knowledge Gaining/Sharing represent the largest categories of
the domain. Most often, a gain in efficiency and maximized effectiveness can be
achieved as optimization. The most common problem is the missing or only
difficult generalization of the presented concepts.
