Decision Support Method Based on Default Rules
基于缺省规则的决策支持方法

The Rough set theory was deeply researched,and algorithms for mining default rules based on Rough set theory was proposed.An analysis method for decision support based on default rules was presented.This method could make the best use of the information of decision system,and reason in absence of knowledge under strict time constraints.Probation showed that this method was less susceptible to noise,and can provide powerful decision support.
