【摘要】 为适应故障诊断中动态变化的环境和满足求解复杂系统全部任务的要求,本文以诊断决策问题的结构及建模过程的层次性为基本思想,提出用立体分层Petri网作为可视化建模支持工具支持嵌套式建模,研究了诊断系统重构的立体分层Petri网框架,并详细分析了诊断系统资源调度的Petri网模型、多智能体诊断系统重构的Petri网模型以及功能智能体执行重构的Petri网模型,全文通过实例说明了Petri网模型的设计方法,最后给出了立体分层Petri网模型的求解方法。更多还原

【Abstract】 To adapt the model in reconfiguring fault diagnosing to dynamic environment and the needs of solving the tasks of complex system fully, based on the thought of the structure of diagnostic decision and hierarchy in modeling, the paper presents cubic hierarchy Petri Nets used as visualized modeling tools to support the nesting modeling, researching the cubic hierarchy Petri Nets framework structure of reconfiguring multi-agent diagnosis system and analyzing the resource scheduling Petri Nets model, cubic hierarchy Petri Nets model of reconfiguring multi-agent diagnosis system and Petri Nets model of executing reconfiguring function agent. Examples are used to illustrate the design method of Petri Nets model. Finally, the paper gives a computing algorithm for cubic hierarchy Petri Nets.更多还原
