Interpreting Invariant Composition in the B Method Using the Spec# Ownership Relation: A Way to Explnent can assume its invariant without having to prove it. But, . users must deal with important architecture restrictions that ensure the soundness of reasonings involving invariants. Moreover, understanding how these restrictions ensure soundness is not trivial. This paper studies a meta-model of i

Chorus Angelorumto that of monotonic ones in general. We explore the impact of this on our theory of substitutions [6], discovering two dual new normal forms for our new substitutions which we exploit to formulate two new first-order tests of refinement between them.

Augmenting B with Control Annotations written for B machines in a verifiable way. Controllers are consistent if they call operations only when they are enabled. Previous work has established a way of verifying consistency between controllers and machines by translating control flow to AMN and showing that a . is preserved. This paper o

Justifications for the Event-B Modelling Notationble. The simplicity of the notation takes also into account the support by a modelling tool. This is important because Event-B is intended to be used to create complex models. Without appropriate tool support this would not be possible. This article presents justifications and explanations for the c

Instantiation of Parameterized Data Structures for Model-Based Testingen involves the use of parameterized data structures in order to be more general (such a model should be sufficient to test many implementation variants) and to abstract irrelevant details. Consequently, the validation engineer is sooner or later required to instantiate these parameters. At the curr

Starting with these patterns as a motivation, this paper discusses various issues concerning the concept of patterns for the . and explores a number of patterns that could be
