Statistical model checking for cyber-physical systems

Abstract

Statistical Model Checking is useful in situations where it is either inconvenient or impossible to build a concise representation of the global transition relation. This happens frequently with cyber-physical systems: Two examples are verifying Stateflow-Simulink models and in reasoning about biochemical reactions in Systems Biology. The main problem with Statistical Model Checking is caused by rare events. We describe how Statistical Model Checking works and demonstrate the problem with rare events. We then describe how Importance Sampling with the Cross-Entropy Technique can be used to address this problem. © 2011 Springer-Verlag.
