摘　　要：随着计算机技术和网络通信技术的高速发展,对于并发分布式系统,已经提出了进程代数以及Petri网等形式化分析方法。近年来由于移动互联网的出现和快速发展,通过在进程代数中增加移动性得到了pi演算,与此同时,Petri网领域也采用谓词/变迁网、颜色网等构建移动系统模型。但它们仍存在一些不足之处。在此基础上,A.Asperti和N.Busi提出了移动网这一系统模型。移动网是在Petri网的基础上增加了移动性并结合了进程代数的优势得到的,适用于描述和刻画移动计算系统。然而,目前并没有对于移动网相应分析方法的研究。为此开展了移动网模型分析方法的研究,给出了移动网可达树的构造算法,提供了移动网模型可达性分析方法,并对移动车辆电话通信系统实例进行了分析。With the fast development of computer technology and network communication technology,process algebra,Petri net and other formal analysis methods were proposed for concurrent distributed systems.Due to the emergence and rapid development of the mobile internet in recent years,pi calculus is developed by adding mobility to process algebra,and at the same time,Petri nets field also uses predicate/transition net and color net to model the mobile system.But there still exist some weakness of them.Based on all previous works,A.Asperti and N.Busi proposed mobile net.Mobile net is obtained by adding mobility to Petri net and combining with the strengths of process algebra.It is suitable for the description of mobile computing system.However,no corresponding analysis method of mobile net has been developed now.Hence,this paper studied the analysis method for mobile net.The construct algorithm of the reachability tree of mobile net was proposed,and the reachability analysis method based on its reachability tree was provided.In addition,an example of the mobile vehicle telephone communication system was illustrated to demonstrate the effectiveness of this method.
