一类加权自动机的模型检验

Model Checking for a Class of Weighted Automata

Peter Buchholz, Peter Kemper

摘要:

在过去的十年中,已经提出了大量不同的模型检验方法。不同的方法适用于不同的模型类型,包括不定时,定时,概率和随机模型。本文提出了一种新的模型检验技术框架,其中包括一些已知的方法,但扩大了可将模型检验应用于一般加权自动机类的模型类别。该方法允许一个简单的适应模型检验的模型,尚未考虑为此目的。可以应用模型检验的那些新模型类型的例子是max/plus或min/plus自动机,它们是描述不同形式的动态系统和优化问题的良好建立的模型。在这种情况下,模型检验可用于验证系统的时间或定量属性。本文首先简要介绍了我们的类加权自动机,作为一个非常一般的模型类型。然后给出了值计算树逻辑(CTL)的$) is introduced as a natural extension of the well known branching time logic CTL. Afterwards, algorithms to check a weighted automaton according to a CTL$公式。最后,给出了加权自动机和CTL$的互模拟。

英文摘要:

A large number of different model checking approaches has been proposed during the last decade. The different approaches are applicable to different model types including untimed, timed, probabilistic and stochastic models. This paper presents a new framework for model checking techniques which includes some of the known approaches, but enlarges the class of models for which model checking can be applied to the general class of weighted automata. The approach allows an easy adaption of model checking to models which have not been considered yet for this purpose. Examples for those new model types for which model checking can be applied are max/plus or min/plus automata which are well established models to describe different forms of dynamic systems and optimization problems. In this context, model checking can be used to verify temporal or quantitative properties of a system. The paper first presents briefly our class of weighted automata, as a very general model type. Then Valued Computational Tree Logic (CTL$) is introduced as a natural extension of the well known branching time logic CTL. Afterwards, algorithms to check a weighted automaton according to a CTL$ formula are presented. As a last result, a bisimulation is presented for weighted automata and for CTL$.
