"315","Use case scenarios as verification conditions: Event-B/Flow approach","Model-oriented formalisms rely on a combination of safety  constraints and satisfaction of refinement obligations to demonstrate model correctness. We argue that for a significant class of models a substantial part of the desired model behaviour would not be covered by such correctness conditions, meaning that a formal development potentially ends with a correct model inadequate for its purpose. In this paper we present a method for augmenting Event-B specifications with additional proof obligations expressed in a visual, diagrammatic way. A case study illustrates how the method may be used to strengthen a model by translating use case scenarios from requirement documents into formal statements over a modelled system.","http://deploy-eprints.ecs.soton.ac.uk/315/","Iliasov, Alexei","Troubitsyna, Elena","       <span class=\"person_name\">Iliasov, Alexei</span>     (2011)  <a href=\"http://deploy-eprints.ecs.soton.ac.uk/315/\"><em>Use case scenarios as verification conditions: Event-B/Flow approach.</em></a>              In:         Software Engineering for Resilient Systems, Proc. of 3rd International Workshop.
