复杂诊断系统的MAS分布式协作方法

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,研究一种基于MAS的分布式智能监控系统。以诊断决策问题的结构及建模过程的层次性为基本思想,基于诊断任务的多层次混合分解策略,提出融合不同表达方式和推理机制的多Agent并行诊断结构,建立了具有公共属性的智能体模块化层次结构,实现了基于MAS多层分布式黑板模型的智能监控系统。工程应用效果验证了多智能体结构框架下复杂系统分布式求解的可行性和有效性。

Distributed Cooperation Solution Method of Complex Diagnosis System Based on MAS

To adapt the model in reconfiguring fault diagnosis to dynamic environment and the needs of solving the tasks of complex system fully,the paper introduced multi-agent and related technology to the complicated fault diagnosis,an integrated intelligent control system is studied in this paper.With the basic thought of the structure of diagnostic decision and hierarchy in modeling,and on multi-layer decomposition strategy of diagnosis task,a multi-agent synchronous diagnosis federation integrated different knowledge expression modes and inference mechanisms are presented,the organization and evolution of agents in the system are proposed.Layered structure of abstract agent with public attributes is build.The application shows that the proposed control structure successfully solves the fault diagnose problem of the complex plant,and the special advantage in the distributed domain.
