Multi-level modeling challenges are designed as benchmark modeling scenarios that aim to support objective comparisons among multi-level modeling approaches, allow technologies to demonstrate their abilities, stress-test technologies in order to expose potential weaknesses, and deepen the mutual understanding of approaches.
In collaboration with Vektor Informatik GmbH, we initiated a new MULTI Challenge for 2026.
The 2026 edition of the MULTI challenge addresses type squares in object models ([1], [2]). We assume type-square patterns to be frequently encountered in systems-engineering contexts. Vektor Informatik GmbH develops software solutions that are used in automotive engineering. One of Vector's core software products is PREEvision, which is marketed as "Vector’s integrated development environment for mastering the complexity of modern software-defined systems." This year's challenge is based on concepts represented by Vector in PREEvision.
Contributions to the challenge should be submitted as posters. The solutions to the challenge are planned to be presented in a separate poster session during the workshop. For each accepted poster submission at least one of the authors is expected to present the solution in person at the workshop. Posters should be submitted via mail to the workshop organizers. Posters will not be peer-reviewed and they will not appear in the proceedings of the workshop. Acceptance is only determined upon whether or not a submission addresses the challenge description. Further organizational information considering, e.g., the poster format will be provided ASAP. We currently plan to organize a joint journal publication for accepted poster contributions.

Solutions to previous challenges (Warehouse Challenge, Collaborative Challenge, Process Challenge) are still welcome. More information on previous challenge editions is provided here.
