In domain-specific modeling languages a variety of constraints originating from different resources have to be considered and integrated into a verification process to ensure a model's correctness. The basis of common model checking methods are constraints derived from meta-model specifications. Besides the meta-model, these constraints often derive from a domain's knowledge. In principle, the heuristic rules and data formulated by domain experts are not precise. To cope with vagueness in the domain knowledge, the concept of fuzzy sets is used. This work therefore describes an approach to integrate fuzzy sets and constraints expressed in the Object Constraint Language (OCL) in a combined constraint reasoning process. The approach is exemplified by introducing a domain-specific modeling language (DSL) for the scope of arrival management.
