Abstract. The engineering of supervisory controllers for large and complex cyber-physical systems requires dedicated engineering support. The Compositional Interchange Format language and toolset have been developed for this purpose. We highlight a model-based engineering framework for the engineering of supervisory controllers and explain how the CIF language and accompanying tools can be used for typical activities in that framework such as modeling, supervisory control synthesis, simulationbased validation, verification, and visualization, real-time testing, and code generation. We mention a number of case studies for which this approach was used in the recent past. We discuss future developments on the level of language and tools as well as research results that may be integrated in the longer term.

This paper covers the Rigorous Examination of Reactive Systems (RERS) Challenge 2019. For the first time in the history of RERS, the challenge features industrial tracks where benchmark programs that participants need to analyze are synthesized from real-world models. These new tracks comprise LTL, CTL, and Reachability properties. In addition, we have further improved our benchmark generation infrastructure for parallel programs towards a full automation. RERS 2019 is part of TOOLympics, an event that hosts several popular challenges and competitions. In this paper, we highlight the newly added industrial tracks and our changes in response to the discussions at and results of the last RERS Challenge in Cyprus.

The Eclipse Supervisory Control Engineering Toolkit (ESCET™) is an open-source project to provide a model-based approach and toolkit for developing supervisory controllers, targeting their entire engineering process. It supports synthesis-based engineering of supervisory controllers for discrete-event systems, combining model-based engineering with computer-aided design to automatically generate correct-by-construction controllers. At its heart is supervisory controller synthesis, a formal technique for the automatic derivation of supervisory controllers from the unrestricted system behavior and system requirements. Vital for the future development of these techniques and tools is the ESCET project’s open environment, allowing industry and academia to collaborate on creating an industrial-strength toolkit. We report on some crucial developments of the toolkit in the context of research projects with Rijkswaterstaat and ASML that have considerably improved its capability to deal with the complexity of real-life systems as well as its usability.
