摘　　要：对数据的性质、数据之间的关系进行了讨论,并由此对决策表进行了分类。研究了协调决策表所需要的必要的数据个数,这对数据采集有着实际的指导意义和经济意义。讨论了协调决策表的数据约简,并证明其不影响进一步的属性约简和规则提取。基于数据的协调性,对协调决策表的属性约简进行了研究,并提出了一种规则提取方法。最后,用实例验证了该方法的有效性。The classification of the decision table is discussed based on the study of the data properties and the relations between them, The necessary data numbers about the consistent decision table is discussed too. The method of the data reduction about the consistent decision table is presented and it does not affect the next processes such as attribute reduction and rule extraction of the decision tables, The methods of the attribute reduction and a method of the rule acquisition of the consistent decision table are given based on the data consistency, The example proves that the methods are valid.

关 键 词：协调决策表 属性约简 数据约简 规则提取
