  Automation systems are increasingly being used in dynamic and various
operating conditions. With higher flexibility demands, they need to promptly
respond to surrounding dynamic changes by adapting their operation. Context
information collected during runtime can be useful to enhance the system's
adaptability. Context-aware systems represent a design paradigm for modeling
and applying context in various applications such as decision-making. In order
to address context for automation systems, a state of the art assessment of
existing approaches is necessary. Thus, the objective of this work is to
provide an overview on the design and applications of context and context
models for automation systems. A systematic literature review has been
conducted, the results of which are represented as a knowledge graph.
