Verifying Reflex-software with SPIN: Hand Dryer Case Study

Process-oriented programming is a natural way to describe control software as a set of communicating processes with executable states, that allows to speed up its development. The Reflex language is one of the representatives of the family of process-oriented languages. The paper justifies the possibility of applying the model checking method for verification of Reflex programs using the hand dryer case study. The case study includes specification of requirements for the hand dryer, control software in Reflex for it, the result of translation of the Reflex program and the requirements into the input language Promela of the model checker SPIN and LTL formulas, respectively, as well as verification of these formulas in SPIN.
