基于序关系的多准则粗集决策方法及应用

从序关系的角度研究多准则决策问题,提出了基于序关系和粗糙集理论的多准则决策方法的系统流程.针对传统定性转换方法信息丢失和导致信息表不一致的缺陷,提出了一种新的定量转换方法,将有序表转换成两两比较表.给出了基于粗糙集的改进RG序规则挖掘算法,并将其应用于两两比较表上以获取供决策使用的排序规则.最后,将该决策方法应用于航材偏好选址问题,决策结果说明了该方法的可行性和有效性.

Research and Application of Multi-Criteria Decision Making Method based on Order Relation and Rough Set

The problem of multiple criteria decision is considered from the perspective of order relation in this paper.The systemic flow of decision-making method based on order relation and rough set theory is put forward.A novel quantitative method transforming ordered information tables to pairwise comparison tables is proposed,to overcome the shortage of information losing and inconsistency which qualitative method induced.The Rough Set based approach to mine ordering rules corresponding to quantitative transforming is discussed.At last,the application of the proposed decision-making method to select the preference aeronautic material supply sites demonstrates its usefulness and effectiveness.
