Statically Defined Dynamic Architecture Evolution

There are a variety of contexts where dynamic architecture evolution is needed. The context we have been working in is that of providing architecture models of NASA training simulations for manned space exploration. In this context, as in many others, we do not need unrestricted dynamic evolution, but only a limited form of dynamic evolution where the transitions and boundaries of that evolution are well understood. We present our approach to this restricted form of dynamic evolutions in the context of an abstract architecture model and use an architecture of architectures with transition connectors as the means of prescribing our statically defined dynamic architecture evolution. Further, we present an incremental mechanism for generating the needed architectures and validate our approach with an implemented prototype.
