一种不一致不完备信息系统的最优选择及规则约简方法研究

Optimization Selection and Rules Extraction in Inconsistent and Incomplete Information System

在分析不一致不完备信息系统规则提取的基础上,提出了先将不完备信息系统分为一致的和不一致的信息系统后再求其最优选择的方法。然后利用改进的分辨矩阵对所求得的不一致最优选择进行决策规则提取,并给出不确定决策规则的决策精度。最后,通过应用例子证明了本文提出方法的有效性。

This paper analyzes the rules extraction in inconsistent and incomplete information system, and presents an advanced algorithm to acquire the optimized selection of incomplete information system which is divided into consistent subsystem and inconsistent subsystem. At the same time, a method based on an amended discernable matrix for rules extraction in inconsistent optimized selection is proposed. The possible rules precision in inconsistent information system is given. The effectiveness of the proposed method in the paper is demonstrated by an application example.
