摘　　要：针对在实际问题中不完备信息系统普遍存在的情况,提出一种一致性表征填充方法,将信息系统对象的条件属性对它们决策的影响程度进行量化,根据对一致性的影响程度,找出与有缺失属性的对象在一致性程度上贴近的对象进行填充,将不完备信息系统合理完备化。结果证明其是合理有效的。Aiming at the instance under actual circumstance that incomplete information system is ubiquitous, this paper puts forward a coherence representation filling method, makes the degree at which their decision is infected by condition attribute of information system object measurable, finds out and fills the object which is close to the object with missing attribute at coherence degree, according to the degree at which the coherence infected. It makes incomplete information system mature. The result is proved to be reasonable and effective.
