Exploring the Twin Peaks using Probabilistic Verification Techniques

System requirements and system architecture/design co-evolve as the understanding of both the problem at hand as well as the solution to be deployed evolve---the Twin Peaks concept. Modeling of requirements and solution is a promising approach for exploring the Twin Peaks. Commonly, such models are deterministic because of the choice of modeling notation and available analysis tools. Unfortunately, most systems operate in an uncertain environment and contain physical components whose behaviors are stochastic.
