    Abstract

    This presentation introduces the Markov Reward Automaton (MRA), an extension of the Markov automaton that allows the modelling of systems incorporating rewards in addition to nondeterminism, discrete probabilistic choice and continuous stochastic timing. Our models support both rewards that are acquired instantaneously when taking certain transitions (action rewards) and rewards that are based on the duration that certain conditions hold (state rewards). In addition to introducing the MRA model, we extend the process-algebraic language MAPA to easily specify MRAs. Also, we provide algorithms for computing the expected reward until reaching one of a certain set of goal states, as well as the long-run average reward. We extended the MAMA tool chain (consisting of the tools SCOOP and IMCA) to implement the reward extension of MAPA and these algorithms.
