ProbReach: A Tool for Guaranteed Reachability Analysis of Stochastic Hybrid Systems

Abstract: In this paper we present a summary of our work on probability reachability in stochastic hybrid systems (SHS). In particular, we give an overview of ProbReach, a tool for computing probabilistic reachability in SHS which we introduced in [18]. We also present and an overview of our recent theoretical extensions and modification of the tool.

“…Abstractions of stochastic models are well-studied (Abate et al 2008;Alur et al 2000), with applications to stochastic hybrid Lavaei et al 2022), switched (Lahijanian, Andersson, and Belta 2015), and partially observable systems (Badings et al 2021;Haesaert et al 2018). Various tools exist, e.g., StocHy , ProbReach (Shmarov and Zuliani 2015), and SReachTools (Vinod, Gleason, and Oishi 2019). However, these papers only reason over uncertainty in a probabilistic way but do not ensure robustness as we do.…”

“…Other Formalisms. Several existing formalisms for stochastic hybrid models do not fit into the proposed classification, as they focus e.g., solely on randomly distributed initial states [18] or on a non-deterministic choice over discrete probability distributions for choosing a successor state [21].…”
