针对装备体系规模大、层次多、成员彼此分离、不断演化的特点,以及体系可靠性预计与分配困难的问题,在充分研究体系内涵的基础上,结合美国国防部体系结构框架(Department of Defense Architecture Framework,DoDAF)和流程分析研究方法,提出了一种基于时间Petri网流程分析的装备体系可靠性建模与分析方法,详细分析了体系结构和使用流程的建模过程,构建了装备体系的可靠性计算模型.以某机场航空保障体系为例,说明了基于流程的体系可靠性建模分析的详细过程,通过ExSpect(Executable Specification Tool)仿真软件,得出了装备体系流程的执行时间和可靠度仿真结果.%Considering the large-scale, multi-level, separated and evolving characteristics of equipment sys-tem-of-systems (SoS), the modeling and analysis method is developed to solve the difficulty of prediction and allocation for equipment SoS reliability. This method, including the Department of Defense Architecture Framework (DoDAF) and process methods, is based on timing Petri net. After detailed analyzing the architecture and service process modeling procedure, the reliability calculation model of equipment SoS is built. A brief example of aviation support SoS in an airport is given to illustrate the process-based procedure of SoS reliability modeling and analyzing. The process execution time and reliability simulation results of equipment SoS are obtained through the Executable Specification Tool (ExSpect) simulation software.
