摘要
针对环境中存在的不确定性因素对信息物理融合系统(CPS)的影响,提出模型可能性混成自动机,在此基础上给出可能性CPS软件模型属性验证的描述语法和语义以及该模型的可能性动态验证方法。通过验证其可达性和安全性,理论证明和实例分析表明该方法是有效的,可描述不确定环境因素下的CPS系统的验证。
Due to the influence of uncertainty factors cyber-physical systems(CPS)in the environment,the property syntax and semantic of possibility CPS software model based on possibility mixed automaton is given in this paper.Meanwhile,the systematic verification method of possibility CPS model is given.Finally,an example analysis shows this method is valid,and it can describe the verification of CPS on the uncertain environment factors.
