Resumen
Modern information systems need to be able to deal with uncertainty and variability, as well as to support the evolution of business processes. In this work, we apply two flexible and configurable modeling approaches to model the process of the student enrollment at a higher education institution. A model based on the configuration of the reference model requires a comprehensive reference model, while the model based on the model structure adaptation contains a minimal reference model. Both modeling approaches proved to be applicable to modeling the process of the student enrollment at a higher education institution.
