摘要
介绍了基于Rough集理论的知识表达及知识获取方法。通过深入研究Rough集的相关理论 ,发现了分辨矩阵的若干有用性质 ,利用这些性质使Rough集理论中的求核与约简问题得以解决。并且将所得结果应用于智能维修决策支持系统中 ,建立了基于Rough集理论的维修资源配置知识的表达、获取和应用体系 ,提高了智能维修决策支持系统的智能决策水平。进而重点讨论了有决策信息系统的约简与规则获取的问题。
Recommend a method of knowledge representation, acquisition based on Rough set theory. Find out several useful nature of the discernable matrix through further research on the relevant theory of Rough set, and as a result the problems of finding core and reduction of Rough set theory have been solved in the end by using these nature. With the use of these results in intelligent maintenance DSS, a system of knowledge representation, acquisition and application based on Rough set theory can be found and be put forward to improve intelligent decision-making level of intelligent maintenance DSS. Furthermore, especially discuss the matters of reduction and rules obtaining on the information system with decision. Regard the decision-making process of configuring maintenance resources as an example to prove the validity of the result obtained finally.
