摘要
主要讨论如何把形式化方法应用于面向对象的软件开发过程中 ,以提高软件的安全性和可靠性 ,并给出一个小型交通控制系统的形式化规范和验证实例。
OO is primarily based on diagrams or natural language text, which cannot express precise semantics. Formal methods can not only express rigorous requirement,but also verify completeness and consistency of system. How formal methods can be used into object —oriented development in order to improve safety and dependency of software is considered. Moreover, a case study in specification and verification of Generalized Railroad Crossing (GRC) is given.
