基于概率信息系统决策规则的R_0三I决策推理

R_0-type triple-I decision inference based ondecision rules of probability information systems

讨论了一种概率信息系统用于表示对象与属性值之间的关系存在不确定性的信息.使用粗糙集和证据合成理论中的方法,给出了获取概率信息系统的扩展决策规则集的一般方法.使用R0三I推理方法实现了基于扩展决策规则集的R0三I决策推理判断.

Probability information systems, which are used to represent the uncertainty information between objects and attributes, are discussed. Based on rough sets and evidence combining theory, a general method of extracting the extension decision rules of probability information system is given. Based on the idea of R_0-type triple-I inference, R_0-type triple-I decision inference can be implemented by the extension decision rules.
