Modelling Architecturally Neutral Realtime Systems

The current trend in Model Driven Architecture is to use model transformation to refine a model from a platformindependent model to a platform-specific model, resulting in a linear development process. With the advent of commercially available realtime and safety critical Java implementations as a basis for platform neutral realtime systems, one could raise the level of reuse in modeling realtime systems by keeping platform independent information completely separate from platform specific information, so that model refinement is done by adding modeling aspects and maps between aspects rather than by model transformation. The result is a modeling process that is less order dependent, thereby supporting the full flexibility of Java Technology even for realtime system design.
