CDS/CIMMS Lunchtime Seminar: Probabilistic Verification of Stochastic Hybrid Systems: Theory, Computations and Applications in Systems Biology Alessandro Abate, Electrical Engineering and Computer Sciences Department, University of California at Berkelely Friday, June 22, 200712:00 PM to 1:30 PM 114 Steele (CDS Library) An important problem in hybrid systems theory is reachability analysis. In general terms, a reachability problem consists in evaluating if a given system will reach a certain set during some time horizon, starting from a set of initial conditions. This problem arises, for instance, in connection with those safety verification problems where the unsafe conditions for the system can be characterized in terms of its state entering some unsafe set. In a stochastic setting, the safety verification problem can be formulated as that of estimating the probability that the state of the system remains outside the unsafe set for a given time horizon. If the evolution of the state can be influenced by some control input, the problem becomes that of verifying if it is possible to keep the state of the system outside the unsafe set with sufficiently high probability by selecting a suitable control input. |
