We exhibit local conditions on components which are sufficient to ensure global correctness of a software system. Finally, we show how restrictions on the architecture of software systems may guarantee these conditions.

Kognitionstheoretische Modelle,abelle/HOL). This work aims at a foundation to formalise the full abstract machine notation, in order to produce a formally checked proof obligation generator. The formalisation is based on the B-Book. First we present an encoding of the mathematical basis. Then we formalise generalised substitution

Klaus Hasemann,Erich Ch. Wittmannn different complementary ways, how a system is allowed to evolve. Such descriptions are independent of the proposed evolutions of the system, which are defined, as usual, by means of a number of operations. Some proof obligations are thus proposed in order to reconcile the two points of view. We ha

An alternative notion is proposed called retrenchment, which allows information to migrate between I/O and state aspects of operations at different levels of abstraction, and which allows only a fraction of the high level behaviour to be c

Perspektiven der Mathematikdidaktik formal method. Our goal is to retain some OOM advantages and produce a flexible and reliable specification, and through the use of our example, we show 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 th

https://doi.org/10.1007/978-3-642-65078-9 is shown how the B method can be used to define implementation independent modular specifications. Benefits are related to the re-use of verified and perennial specifications for control systems facing a fast evolution of implementation technologies. Limits are related to the compliance of formal m
