This document summarizes a systematic literature review on using component-based principles and practices for architecting cyber-physical systems. The review analyzed existing research according to a classification framework and identified gaps. It found that over half the primary studies were published between 2014-2015, indicating growing interest. However, component models for cyber-physical systems have not fully explored properties like adaptation and dynamics. The review aims to enlarge the scope of architecting cyber-physical systems and cover gaps between needs in the field and current realizations.
