Modeling Dynamic Architectures Using Nets-Within-Nets

Current modeling techniques are not well equipped to design dynamic software architectures. In this work we present the basic concepts for a dynamic architecture modeling using nets-within-nets. Netswithin-nets represent a powerful formalism that allows active elements, i.e. nets, to be nested in arbitrary and dynamically changeable hierarchies. Applying the concepts from nets-within-nets, therefore, allows us to model complex dynamic system architectures in a simple way, which us to design the system at different levels of abstractions using refinements of net models. Additionally to the conceptual modeling of such architecture, we provide a practical example where the concept has been successfully applied in the development of the latest release of Renew (Version 2 of the multiformalism Petri net IDE1 ). The overall monolithic architecture has been exchanged with a system that is divided into a plug-in management system and plug-ins that provide functionality for the users. By comb...
