Peter Bulychev, Franck Cassez, Alexandre David, Kim Guldstrand Larsen, Jean-François Raskin, Pierre-Alain Reynier
2012 Lecture Notes in Computer Science  
We apply our approach to timed systems. We have developed a tool prototype and analyze the performance of our optimization algorithm on two case studies.  ...  We consider the problem of controller synthesis under imperfect information in a setting where there is a set of available observable predicates equipped with a cost function.  ...  One of the applications of Timed Automata is controller synthesis, i.e. the automatic synthesis of a controller strategy that forces a system to satisfy a given specification.  ...

Maximizing the Robustness of TDMA Networks with Applications to TTP/C

Bruno Gaujal, Nicolas Navet
2005 Real-time systems  
If one wants to minimize the probability of losing all replicas of a given message, then the optimal policy is to spread the replicas over time.  ...  On the contrary if one wants to minimize the probability of losing at least one replica, then the optimal solution is to group all replicas together. This is proved by using majorization techniques.  ...  Acknowledgments The authors would like to thank the anonymous referees for their helpful comments and suggestions.  ...
