Summary

Two main activities in design are synthesis and analysis of alternatives. Modeling and simulation is mostly used in the analysis phase, although an advantage could be gained by using it in the synthesis phase. This advantage is the possibility to analyze each design decision while still in the synthesis phase. To achieve this, a gap needs to be closed between this approach and the current modeling and simulation formalisms. We consider this gap to mainly lie in the inability to incrementally construct, structure, and evaluate alternatives for a design process within a modeling and simulation environment. This paper introduces a formalism for the development of such an environment, capable of actively supporting the design of complex engineered systems through modeling and simulation. This formalism provides the ability to structure intermediate models, allowing the generation of, and the navigation through multiple worlds.
