基于广义可能性测度的线性时间性质定量模型检验

Quantitative Model Checking of Linear-Time Properties Based on Generalized Possibility Measures

Yongming Li

摘要:

基于可能性测度的线性时间特性的模型检验在以前的工作(Y。Li和L. Li,模型检验基于可能性度量的线性时间特性,IEEE Transactions on Fuzzy Systems,21(5)(2013),842-854)。然而,在以前的工作中考虑的线性时间性质是经典的和定性的,系统的可能性信息没有考虑在所有。本文将研究基于广义可能性测度的模糊线性时间性质的定量模型检验。使用可能性信息来描述系统的模型以及系统需要遵守的属性,以识别模型/属性中的不确定性。系统采用{ \sl广义可能性Kripke结构}(GPKS,简称)建模,其性质用模糊线性时间性质描述.具体地,研究了GPKS系统的可达性、总是可达性、约束可达性、重复可达性和持续性的模糊线性时间性质。介绍了GPKS中的模糊正则安全性质和模糊$ω-$正则性质,深入研究了模糊有限自动机对模糊正则安全性质和模糊$ω-$正则性质的验证.证明了有限GPKS中模糊正则安全性和模糊$ω-$正则性的验证可以转化为本文所介绍的产品GPKS中(总是)可达性和重复可达性(持久性)的验证.文中给出了几个算例来说明本文所提出的方法。

英文摘要:

Model checking of linear-time properties based on possibility measures was studied in previous work (Y. Li and L. Li, Model checking of linear-time properties based on possibility measure, IEEE Transactions on Fuzzy Systems, 21(5)(2013), 842-854). However, the linear-time properties considered in the previous work was classical and qualitative, possibility information of the systems was not considered at all. We shall study quantitative model checking of fuzzy linear-time properties based on generalized possibility measures in the paper. Both the model of the system, as well as the properties the system needs to adhere to, are described using possibility information to identify the uncertainty in the model/properties. The systems are modeled by {\sl generalized possibilistic Kripke structures} (GPKS, in short), and the properties are described by fuzzy linear-time properties. Concretely, fuzzy linear-time properties about reachability, always reachability, constrain reachability, repeated reachability and persitence in GPKSs are introduced and studied. Fuzzy regular safety properties and fuzzy $ω-$regular properties in GPKSs are introduced, the verification of fuzzy regular safety properties and fuzzy $ω-$regular properties using fuzzy finite automata are thoroughly studied. It has been shown that the verification of fuzzy regular safety properties and fuzzy $ω-$regular properties in a finite GPKS can be transformed into the verification of (always) reachability properties and repeated reachability (persistence) properties in the product GPKS introduced in this paper. Several examples are given to illustrate the methods presented in the paper.
