Guest editorial to the theme section on Multi-Paradigm Modeling for Cyber-Physical Systems.

This theme section aims to disseminate the latest research results in the area of Multi-Paradigm Modeling for Cyber-Physical Systems (MPM4CPS). MPM has a long tradition within the Model-Driven Engineering community, e.g., several workshops have been held at the MODELS conference for over more than a decade. The MPM4CPS workshop series is a continuation of the successful MPM workshop series with a stronger focus on CPS as especially these systems pose several new challenges on the engineering process and beyond. This theme section covers papers on the foundations and applications of MPM for CPS. In total, we accepted five submissions for publication in the theme section after a thorough peer-reviewing process.
