The fourth edition of the International Workshop on Executable Modeling (EXE) was held on October 14, 2018 in Copenhagen, Denmark, as part of the satellite events of the ACM/IEEE 21st International Conference on Model Driven Engineering Languages and Systems (MODELS 2018).
In times of increasing system complexity, time-to-market pressures, and the need for high quality systems, executable models gain importance in the development of software-intensive systems. This is due to their abstraction power allowing the early analysis of complex system behaviors reducing efort and cost in the development and increasing system quality.
The objectives of the International Workshop on Executable Modeling (EXE) are to draw attention to the potentials and challenges of executable models and to advance the state-of-the-art in executable modeling. In 2018, the workshop was already held for the fourth time. For this fourth edition, submissions of research papers, experience reports, position papers, and tool demonstrations on various topics of executable modeling were invited. The topics of interest included methodologies, languages, techniques, and methods for designing and implementing executable modeling languages, model execution tools for the validation, verification, and testing of systems, and techniques for the development of model execution tools.
EXE 2018 was held as a full-day workshop at the ACM/IEEE 21st International Conference on Model Driven Engineering Languages and Systems (MODELS 2018) on October 14, 2018 in Copenhagen, Denmark. Out of eight submissions, four were accepted after a rigorous reviewing process in which each paper was reviewed by three members of the program committee. The accepted papers comprise three research papers presenting novel and innovative approaches in executable modeling, as well as one tool demonstration of a model execution tool.
The following papers were accepted for EXE 2018: (1) “Execution of UTP test cases using fUML” by Marc-Florian
Wendland and Niels Hoppe (2) “A generic solution for weaving business code into executable models” by Eric Cariou, Olivier Le Goaer, Léa Brunschwig and Franck Barbier (3) “On executable models that are integrated with program code” by Marco Konersmann (4) “EmbeddedMontiArc: Textual modeling alternative to Simulink (Tool Demonstration)” by Evgeny Kusmenko, Jean-Marc Ronck, Bernhard Rumpe and Michael von Wenckstern All the materials presented at EXE 2018 can be found on the workshop Website http://modelexecution.org/exe2018. 3
The program committee of EXE 2018 comprised 25 experts in the domain of executable modeling. We thank the program committee members very much for their services in reviewing and discussing the submitted papers.

We thank the organizers of MODELS 2018 very much for hosting EXE 2018 and for their support in the workshop organization. Our special thanks go to the general chair of MODELS 2018, Andrzej Wąsowski, to the workshop chairs Regina Hebig and Thorsten Berger, as well as to the proceedings chairs Daniel Strüber and Önder Babur. Furthermore, we thank all the authors, presenters and participants of EXE 2018. We also want to express our sincere gratitude to Benoit Combemale for agreeing to give the keynote on the past, present and future of executable modeling. Lastly, we thank the members of the EXE 2018 program committee for their timely and high-quality reviews, as well as for their inputs to the workshop program.
