本文提出了一种工具辅助分析和验证安全关键联锁和信号数据的方法。我们展示了如何将联合收割机多个非同质的数据源结合起来,并将这些数据作为数学实体的集合,即集合、关系和函数。然后,我们展示了如何顶级的铁路安全问题可以被分解,通过非正式的结构化论证和正式推理相结合,到正式的验证目标,适合自动验证工具。
This paper presents an approach to a tool-assisted analysis and verification of safety-critical interlocking and signalling data. We show how to combine multiple, non-homogeneous sources of data and render such data as a collection of mathematical entities, namely sets, relations and functions. We then demonstrate how top-level railway safety concerns can be broken down, via a combination of informal structured argumentation and formal inference, into formal verification goals suitable for automatic verification tools.
