Modeling and Aspect Weaving

A model is a simplified representation of an aspect of the world for a specific purpose. Complex systems typically give rise to more than one model because many aspects are to be handled. For software systems, the design process can be characterized as a (partially automated) weaving of these aspects into a detailed design model. While verification is usually feasible on each of the aspects, it is seldom possible on the resulting detailed design because of the size explosion. Hence we need weaving processes that exhibit good composition properties from the point of view of verification. We present an example of such a weaving process for behavioral models represented as scenarios
