The paper “A Compositional Semantics for Repairable BDMPs” by Shahid Khan, Joost-Pieter Katoen and Marc Bouissou (EDF) has been accepted for the 39th International Conference on Computer Safety, Reliability and Security. The paper describes a formal compositional semantics of Boolean-Driven Markov Processes and empirically validates the semantics using a discrete-event simulator for BDMPs.
