【摘要】 在研究当前诊断专家系统的推理控制策略的基础上提出一种称为"会诊式"推理控制策略的诊断推理方法。该方法可有效解决传统推理控制策略容易出现的"匹配冲突"、"组合爆炸"、"无穷递归"及"知识窄台阶"问题,同时在系统简化时保证了推理的精度。建造了基于"会诊式"推理控制策略某型地空导弹的诊断专家系统,仿真表明,"会诊式"推理策略可明显提高诊断精度和提高推理适应能力。更多还原

【Abstract】 Based on the study of the inference and control strategy of ES, a new inferential strategy which named "consultation mode inferential and control strategy" is presented. Fig.(1) shows the structure of this strategy. By definition (4), (5) and eq.(4),(5),(6),(7),(8),we get the mathematical model of the strategy. Based on the new inferential strategy a missile faults diagnosis system (fig.2) is built. Compared with a system (fig.3) based on common strategy, the new system’s performance is perfect. Table 1 gives the result of test of the two systems. It shows the new inferential strategy is effective.更多还原
