WebThe B method is a method of software development based on B, a tool-supported formal method based on an abstract machine notation, used in the development of computer software. [1] [2] Overview [ edit] B was originally developed in the 1980s by Jean-Raymond Abrial [3] [4] in France and the UK. WebFormal development is the use of formal methods as an integrated part of a tool-supported system development process.
