Interface-oriented classification of DEVS models

Model classification is a way to structure and handle knowledge about systems. Using the models external message interface as the classification criterion lays emphasis on the fact that atomic and coupled DEVS models are modular and interchangeable model components. Interface-oriented classification is a means to formalize the conditions of component replacement and coupling validity. It can be used as the basis of advanced modeling methods like multi-modeling and modeling of structurally variant systems.<>
