Based on rough sets theory, crude domain knowledge rules are extracted; dependent factors and antecedent coverage factors of rules are calculated from sample data 该方法充分利用软计算中的模糊集合理论,人工神经网络,粗糙集理论和遗传算法等计算方法优势,弥补它们相互的不足,进行故障诊断。
Fault information, real-time data and reasoning process can be queried by man-machine interface, and the fuzzy knowledge rule base can be maintained by increasing, decreasing and so on 通过系统的人机接口可以对故障信息、实时数据以及推理过程等进行查询,还可对模糊知识规则库进行修改和添加等维护工作。
On the basis of diesel engine's fault modules, the mining of knowledge rules about diagnosis of diesel engine are outlined in detail, including simple knowledge rules mining, cluster analysis and association rules mining 本文在分析柴油机的各种故障模式的基础上,详细分析了柴油机故障诊断规则的挖掘,包括采用常用油液分析方法的简单规则挖掘、聚类分析挖掘及关联规则挖掘。

Therefore, we can make such a discussion about kb that knowledge rule is framed by using temporal logic and using temporal logic assertion to infer . thus makes temporality as the unified symbol of rules which drive in kb 由此,针对知识库,可以做一个这样的探讨:使用时态逻辑对知识规则进行构架,在知识库内则用时态逻辑断言进行推理,从而使得对知识库的规则驱动有了一个统一的标志??时态。
Firstly, the paper introduces temporal logic and it's knowledge representation . secondly, it describes that knowledge rule's structure on temporal logic and gives inference instance and its simulated realization . lastly, it discusses the temporal-driven of kb 本文从时态逻辑及其知识表达开始介绍,并给出了时态逻辑对知识规则的构架与推理的实例在新应用领域的研究与模拟实现,最后对知识库的时态驱动给出探讨。
In the same time, spatial association rules is one of the upmost knowledge rules in the result of spatial data mining . it emphasizes particularly on confirming the relation of data in different fields . it tries to find out the dependence of data in multi-fields 同时空间关联规则是空间数据挖掘结果的一种最主要的知识规则,它侧重于确定数据中不同领域之间的联系,找出满足给定支持度和可信度阈值的多个域之间的依赖关系。
The paper introduced the research methods, development flat, function and structure design, obtaining for expert knowledge, forming knowledge rules, joining with models, and cases of intelligent consequence etc, in expert system joined with models for management and decision making of grape 摘要本文介绍了模型搭载的葡萄栽培管理决策专家系统的研究方法、开发平台、功能结构设计、专家知识获取、知识规则条理化、模型搭载以及智能推理举例等。
Firstly we discussed and determined the feature of turning and milling process, based on which we set up the knowledge rules of the turning cutting tool and milling cutting tool choice . we applied the knowledge rules to the expert system of nc machining process parameters repository, which realized the cutting tool choice of nc machining . we also added the explaining implements of turning and milling tool and perfected the expert system of nc machining process parameters 首先研究确定了车削加工和铣削加工的加工特征;在此基础上,建立了基于加工特征的车刀选择知识规则和铣刀选择知识规则,并将其知识融入到已研制开发的数控加工工艺参数优化专家系统知识库中,实现数控刀具的优选;本文还增加了车刀选择解释器和铣刀选择解释器,完善了数控加工工艺参数优化专家系统。
