Description

Storm is a tool for the analysis of systems involving random or probabilistic phenomena. Given an input model and a quantitative specification, it can determine whether the input model conforms to the specification. It has been designed with performance and modularity in mind.

Modeling formalisms

Storm is built around discrete- and continuous-time Markov models:
  • Discrete Time Markov Chains
  • Markov Decision Processes
  • Continuous Time Markov Chains
  • Markov Automata

Input languages

Storm supports several types of input:
  • PRISM
  • JANI
  • GSPNs
  • DFTs
  • cpGCL
  • explicit

Properties

Storm focuses on reachability queries and its support includes
  • PCTL
  • CSL
  • Expected Rewards
  • Conditional Probabilities
