2014-08-26: Seminar Prof Vladimir Estivill-Castro on Correctness by Construction with Logic-Labelled Finite-State Machines – Comparison with Event-B
Formal methods have seen emergent success recently with the deployment of Event-B. However, Event-B explicitly postulates that models there are not executable. This seems to contradict the parallel emergence of model-driven development (MDD). We show here that logic-labelled finite-state machines (LLFSMs) are effective in carrying out the “correct from construction” agenda of formal methods such as Event-B and simultaneously achieve the aims of MDD. As a result, we obtain models that are directly interpretable, compilable, and executable enabling traceability, transparency and rapid maintainability; while at the same time enabling simulation, validation and formal verification with model checking. Moreover, the Event-B capacity to develop closed models is also very natural with arrangements of LLFSMs; and therefore further safety analysis such as failure-mode effects analysis (FMEA) can be performed. We demonstrate this with two well-known examples in the literature.
