摘要: B is a formal method which enables the automatic generation of an executable code through successive refinements from abstract specification. Unified Modeling Language (UML) specifications can be formally verified by analyzing corresponding specification, and integration UML overcomes drawbacks UML. In this paper Class diagram flight control system presented each class operation mapped to machine. The software behaviors are in form statecharts adopted translate into specification software.Using method, refined failure management added. Finally proof obligations ensure safety for ertical artificial navigation UAV.
