https://doi.org/10.1007/978-3-322-96269-0, we introduce a deduction system that allows to reason in a two-valued logic if new proof obligations called well-definedness lemmas are also proved. We define this deduction s ystem and the new proof obligations that ensure the well-definedness of B components. The practical benefits on the proof mechanisms are then outlined.

Kognitionstheoretische Modelle,enerator. The formalisation is based on the B-Book. First we present an encoding of the mathematical basis. Then we formalise generalised substitutions by the before-after model and we prove the equivalence with the weakest precondition axiomatic model. Finally we define operations and abstract machines.

This permits more of the informal aspects of design to be formally captured and checked. The details are worked out for the B-Method.

Perspektiven der Mathematikdidaktikow how this is achieved. We prove formally that our design meets its informal specification with the help of B-Toolkit Release 3.3.1. We illustrate the approach by the B specification of A Computerized Visitor Information System (ACVIS). Using Object Modeling Technique diagrams allows us to make ACVIS more readable and open for changes.

Synthesising structure from flat specifications,e, the rich type constructions of VDM are useful for the former..In this paper we propose a method which synthesises a structured B design from a flat VDM specification by analysing how type definitions are used within the VDM state in order to generate a corresponding B machine hierarchy.
