摘要

给出了一种描述和验证容错实时程序的转换方法。尽管可能发生系统故障,但这样的程序需要根据其功能和实时性要求证明是正确的。本文论证了一个适合实时系统的表达逻辑,可以自然地对系统故障引起的状态变化进行建模,并确定它们对执行的功能和实时性的影响。

Verification of fault tolerance and real time
A transformational method is given for specifying and verifying fault-tolerant, real-time programs. Such a program needs to be provably correct according to both its functional and real-time requirements, despite the possible occurrence of system failures. The paper demonstrates that a suitably expressive logic for real-time systems makes it possible to naturally model the state changes caused by system failures and determine their effect on the functional and real-time properties of executions.
