弱公平下活性性质的规范和细化的证明义务

Proof obligations for specification and refinement of liveness properties under weak fairness

Hector Ruiz Barradas, Didier Bert

摘要:

在这份报告中,我们提出了一个正式的模型,公平迭代的事件B事件系统。该模型用于证明基本活性属性的证明义务和一般活性属性的细化下的保存。事件的公平迭代模型使用燕尾算子,Broy和Nelson提出的一种算子来模拟公平选择。证明主要是建立在事件公平迭代和最弱前提演算的不动点计算上。

英文摘要:

In this report, we present a formal model of fair iteration of events for B event systems. The model is used to justify proof obligations for basic liveness properties and preservation under refinement of general liveness properties. The model of fair iteration of events uses the dovetail operator, an operator proposed by Broy and Nelson to model fair choice. The proofs are mainly founded in fixpoint calculations of fair iteration of events and weakest precondition calculus.
