针对当前装备体系(system of systems，SoS)任务建模研究深入程度不足问题，提出装备SoS使命任务的概念模型和描述模型，在此基础上，首先对各层级任务的任务线程进行分析与规划，改进传统Petri网，提出一种基于层次确定与随机 Petri 网(hierarchical deterministic and stochastic Petri nets，HDSPN)的装备 SoS 任务线程建模方法，构建面向多层级使命任务的装备SoS任务线程模型。然后，结合基于可达性分析算法(reachability analysis algorithm，RAA)的装备SoS总体任务成功性仿真评估算法，启动仿真模型运行，实现对装备SoS总体任务成功性的有效评估，并通过案例分析，验证了模型的适用性。
Overall evaluation of mission success of SoS based on HDSPN
Aiming at the problem of insufficient research on mission modeling of the equipment system of systems(SoS),the concept model and description model of missions of the equipment SoS are proposed.On this basis,mission threads of each level is analyzed and planned and a modeling method of mission threads of the equipment SoS based on hierarchical deterministic and stochastic Petri nets(HDSPN)is proposed by improving traditional Petri nets.A multi-level mission-oriented mission thread model of equipment SoS is constructed.Then,combined with the simulation evaluation algorithm of the overall mission success of the equipment SoS based on reachability analysis algorithm(RAA),the simulation model is started to run to realize the effective evaluation of the overall mission success of the equipment SoS.The applicability of the model is verified through the case study.
