Abstract: Evolvable architectures are an important design principle in order to cope with the continuously changing requirements for information systems. These changes are induced by changes of the market, changes of the society, and changes of the technology. We propose a design strategy for evolvable architectures, called EVA¹. This approach is component-based and process-centered. We suggest also to consider business process as composed of components. The main focus of this paper are components of business processes in terms of net components and their composition in this approach. We use net components that are based on Petri nets. The nets are restricted FUNSOFT nets. These nets, called FEVA net are used to model business processes as well as their consistent composition.

Keywords: architectures, FUNSOFT nets, temporal logic, components, business processes
