Statistical model checking

We have designed a logic HASL for stochastic systems that can express elaborated performance indices related to path behaviours [46] . We have shown how it can be integrated in the design process of flexible manufacturing systems [47] . We have developed a tool COSMOS for statistical model checking of HASL formula over a stochastic Petri net with general distributions [45] . In parallel, we have developed the first importance sampling method for rare event that still produces a confidence interval (rather than an estimated value) and we have integrated this method in COSMOS [48] .
