远程UUV指挥控制流程分层Petri网建模及延时分析

摘要

Command and control process of remote UUV has many control nodes and is complicated,modeling and analysis of the process is difficult by using traditional modeling methods.In order to improve the modeling ability,hierarchical modeling method based on Petri net is introduced and in order to depict the time character,timed transition is introduced and the computing algorithm is given,based on which,the command and control process model of remote UUV is constructed based on hierarchical timed Petri net model.The simulation results verify the applicability of the proposed model and the effectiveness of the analysis method.This model can be used to in-depth analysis and research on the command and control process of the remote UUV and can also provide reference for the evaluation and improvement of the command and control system of the remote UUV.%对于控制节点多、流程复杂的远程UUV指挥控制流程建模及延时分析问题,传统建模方法往往难于对其进行详细描述和分析.文中建立远程UUV指挥控制流程分层延时Petri网模型,采用基于Petri网的层次化建模方法提升模型对复杂流程的表达能力,将变迁引入时间参数,使模型具备对时间的描述和分析能力,并给出不同结构的延时计算方法.仿真结果表明所建模型可用于对远程UUV指挥控制流程进行分析和计算,分析方法正确、适用性好,可为远程UUV指挥控制系统评价及完善提供参考和技术支持.
