摘要
为设计一种简便而又科学的区间数排序方法,在综合考虑区间数的特点、提取区间数中的隐形数据、对数据进行处理等基础上,根据各个区间数与目标区间数相似度程度的不同,提出了一种新的对区间数进行排序的方法,并提出了这种排序方法的一些优良性质,如:序关系完全性、传递性、等价替换性、区间数长度相等且区间数的属性为效益型时中心越大越好、区间数中心重合时区间越小越好等,充分表明了这种方法的科学性与可行性。最后,通过一个算例说明这种简单、方便、科学的排序方法的操作过程。
A new simple and scientific method for ranking interval numbers is proposed,based on analyzing the characteristics of interval numbers,extracting the data contained in the interval numbers and the difference of similarity degree for every interval numbers to the target.And some properties are developed,such as,complete order relation,transitive,equivalent substitution,the larger of the centers the better of the interval numbers when the length of them are equal and the property of them is efficiency,the smaller of length the better of the interval numbers when the centers of them is the same,which illustrate the feasibility of the technique.Finally,an example is presented to verify that the processing of the method is simple,convenient and scientific.
