Cyber-Physical Systems (CPS) are controlled complex technical systems. On one hand they do exist and behave in the physical world with their dedicated physical and technical rules. On the other hand they are controlled according to certain policies -- frequently by a "tandem" of control systems and human operators. Modern cars, aircrafts, power grids,(More)
Critical infrastructures (CI) such as telecommunication or the power grids and their dependencies are getting increasingly complex. Understanding these – often indirect –dependencies is a vital precondition for the prevention of cross sector cascading failures of CI. Simulation is an important tool for CI dependency analysis, the test of(More)
