Overview

PARAM is a tool with the purpose of handling parametric variants of models specified in a variant of the PRISM language. PARAM is capable of computing the unbounded reachability probability for parametric discrete-time Markov chains. Apart from this, it can also handle special classes of Markov decision processes, as well as reachability rewards for Markov reward models. To speed up computations, it can compute the (strong and weak) bisimulation quotient of parametric models.
