Discrete EVent System Specification (DEVS) is a popular formalism which allows specifying and simulating models. Its main drawback is that its implementation is simulator-specific, i.e. models have to be programmed using an Object-Oriented Language (OOL). In this paper, we introduce DEVS profiles, which are specializations/restrictions of DEVS meta-model, and we explain how to create a DEVS Profile for non-computer scientists. We distinguish two kinds of users: the metamodelers and the modelers. Models designed with DEVS profiles can be mapped onto platform specific models and to object code using a Model Driven Architecture (MDA) approach. DEVS profiles improve the reusability of models.
