vIRONy: A Tool for Analysis and Verification of ECA Rules in Intelligent Environments

Intelligent Environments (IE) are a very active area of research and a number of applications are currently being deployed in domains ranging from smart home to e-health and autonomous vehicles. In a number of cases, IE operate together with (or to support) humans, and it is therefore fundamental that IE are thoroughly verified. In this paper we present how a set of techniques and tools developed for the verification of software code can be employed in the verification of IE described by means of event-condition-action rules. In particular, we reduce the problem of verifying key properties of these rules to satisfiability and termination problems that can be addressed using state-of-the-art SMT solvers and program analysers. We introduce a tool called vIRONy that implements these techniques and we validate our approach against a number of case studies from the literature.
