摘要： A hierarchical knowledge base system is provided to enhance the efficiencies of constructing knowledge bases, making inferences, and understanding and analyzing the contents and state of a fault in a plant. Hierarchical knowledge bases store plant information on the states of plant equipment, media flowing through the plant, control instructions, and a plant system diagram. This information is used to make inferences for the detection of a fault in the plant, the identification of faulty equipment, and the cause of the fault, in stages from an upper layer to a lower layer, and the results of the inferences are displayed. The hierarchical knowledge base is constructed by synthesizing a knowledge base of an upper layer from a knowledge base of a lower layer.

摘要翻译： 提供分层知识库系统，以提高构建知识库的效率，推断，理解和分析工厂故障的内容和状态。 分层知识库存储工厂设备状态，流经工厂的介质，控制指令和工厂系统图的工厂信息。 该信息用于从上层到下层逐级检测工厂故障的检测，故障设备的识别和故障原因，并显示推理结果。 通过从下层的知识库合成上层的知识库构建分层知识库。
