| 摘 要： | 首先定义了决策规则决策属性的简化,并以此为基础定义了决策表决策值的简化,旨在研究决策表条件值简化的对偶问题,即在保持决策表条件属性集不变的前提下它的条件属性集和决策属性集之间的最简函数关系。在这些定义的基础上,给出了决策规则决策属性简化的表达式和决策表决策值简化的表达式。

| Abstract: | The reduction of decision attribute set for the decision rules was defined, on which the reduction of decision values for a decision table was defined. The dualistic problem of reduction of condition values in a decision table was investigated. The reduction of decision values in the decision table was used to present the simplest functional relation between the condition attribute set and the decision attribute set, when the condition attribute set keeps constant. The expression for the reduction of decision attribute set in the decision rules and the expression for the reduction of decision values in the decision table were given. |
