摘要
基于区间数判断矩阵中一些区间数间的特殊关系 ,本文对取数一致及取数互反的区间数运算进行了讨论 ;然后结合问题的实际意义 ,给出区间数判断矩阵一种新的一致性定义并讨论其判别法 ;最后将魏毅强给出的定义与新定义进行了比较 。
Based on the special relation among some interval numbers in the interval number judgement matrix,this paper gives a discussion of operation between these interval numbers-they take a value in consistency or inversion.Then combined with the real meaning of the question,a new difinition of the consistent interval number judgement matrix and its discriminating methods is given.Finally,gives a comparision between the definition of Wei Yiqiang and the new definition,points out two questions of the definition of Wei Yiqiang.
