A METHODOLOGY FOR DESIGNING HIGH CONFIDENCE PATTERN VIA EVENT B

The correct formal design is an achievement in software engineering, but we faced with
challenges to satisfy that. The informal problems types are general or special. The special informal
problems depend on the case study and the general informal problems come from an inexperienced
designer called anti-patterns". In this paper we discuss these two types on Insulin Infusion Pump (IIP)
and sample of UML class diagrams. The proposed approach to formalize IIP is based on using event B.
Finally, we could verify that the code generated from the proposed approach is correct and formal to
use as a pattern. The accuracy of the proposed verification steps are suitable for using to any systems
or medical device. We applied the proposed approach on the sample of eight famous UML class
diagrams used as templates. The method ameliorates the proofpercentage
