针对有序尺度变量，给出了有序信息系统与有序决策表在优势关系下的粗糙集约简定义；
In this paper, with respect to the ordinal variables, the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.
信息系统的属性约简反映了一个决策表的本质信息，为信息系统的数据挖掘奠定的基础。
Attribute reduction of information system is to remove superfluous attributes from information systems while preserving the consistency of classifications the original system provides.
在不改变总体序信息情况下，给出了基于此度量对有序信息系统与有序决策表进行约简的新方法。
Based on this measure, a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.
本文将决策表技术引入管理信息系统作为知识存贮手段，用户可通过决策表自行设置规则集，并用推理机进行演绎推理，从而实现对管理信息系统数据库的智能查询。
Intelligent query for database of MIS is implemented, for storing knowledge with decision table. The user can create rule-set by way of decision table and carry out reasoning.
