B-Method

From Wikipedia, the free encyclopedia

B is a tool-supported formal method based around AMN (Abstract Machine Notation), used in the development of computer software. It was originally developed by Jean-Raymond Abrial in France and the UK. B is related to the Z notation (also originated by Abrial) and supports development of programming language code from specifications. B has been used in major safety-critical system applications in Europe (such as the Paris Métro Line 14), and is attracting increasing interest in industry. It has robust, commercially available tool support for specification, design, proof and code generation.

The method of software development based on B is known as the B-Method.

Compared to Z, B is slightly more low-level and more focused on refinement to code rather than just formal specification – hence it is easier to implement a specification written in B correctly than one in Z. In particular, there is good tool support for this.
