Formal specification of a Haemodialysis Machine (HD Machine) using Event-B

Abstract

This archive contains a formal specification of a haemodialysis machine (HD machine) in Event-B using the Rodin Toolset. We utilise ProR for structuring and tracking requirements. We model the HD machine using iUML-B state-machines and class diagrams, and build a corresponding BMotion Studio visualisation. For verification, we use both theorem proving and model checking techniques. We validate the design of the system using (i) diagrams to aid the modelling of the sequential properties of the requirements, and (ii) ProB-based animation and visualisation tools to explore the system&#39;s behaviour. Some of the safety properties involve dynamic behaviour which is difficult to verify in Event-B. For these properties we use (iii) co-simulation tools to validate against a continuous model of the physical behaviour. Assigned DOI: 10.5258/SOTON/401360</span
