Validating Event-B models using PDDL

Abstract

The formal Event-B method makes it possible to obtain systems or software correct by construction. The modeling activity aims to establish formal models in Event-B. As for the proof activity, it aims at correcting these models. A proven Event-B model is not necessarily valid. We propose to open the Event-B formal method on PDDL in order to further validate Event-B models. We aim to validate the dynamic properties related to the sequence of events authorized on Event-B models. PDDL is a de facto standard language for planning problems. It is equipped with planners to automatically generate solution-plans. To achieve this, we successfully used the MDE approach, Xtext to create an integrated development environment specific to the Event-B language and the Xtend tool to implement our transformation EventB2PDDL and produce PDDL descriptions using a top-down approach.
