Quantitative reasoning mechanism and optimum reasoning environments in intelligent diagnosis 智能诊断的定量推理(QR)机制和最优推理环境
To solve the deficiencies of traditional fault diagnosis methods in equipment maintenance, virtual prototyping was firstly adopted into fault simulation and prediction fields as a new quantitative reasoning mechanism. The modeling process and designing idea of fault simulation and prediction system based on virtual prototyping was illustrated. 为解决传统故障诊断方法在装备维修保障方面的不足,将虚拟样机作为一种新的定量推理(QR)机制引入到故障仿真和预测领域,提出了基于虚拟样机的装备故障仿真预测模型。
To deal with uncertainty of aero-engine maintenance level decision, a fault and performance evaluation knowledge representation model based on fuzzy Petri nets ( FPN ) is proposed. Qualitative and quantitative reasoning algorithm of knowledge base is researched. 在逻辑层次建模方面,针对发动机维修等级推理中的不确定性,建立基于模糊Petri网的发动机故障评估、性能评估知识表达模型,研究知识库的定性和定量推理(QR)算法。
Integrated quantitative reasoning mechanism of fault detection and diagnosis at different hierarchies of underwater vehicles 基于层次模型定量推理(QR)机制的潜水器故障诊断系统设计
