摘要
用区间数表示各因素权重及评判矩阵,定义新的区间数排序方法,给出了一个区间数的综合评价模型,并用实例模拟验证.该模型有效克服由于模糊性而带来的数值不确定性,能够较好地反映决策者的心理状态,有助于信息检索技术方面的研究.
This paper presents a fuzzy comprehensive evaluation decision model based on interval-numbers.The weights of factors and elements of the evaluation matrix are represented by interval numbers and a new interval numbers sequence method is given.The application example shows that the model is efficient.It can overcome the uncertainty of the numerical value owing to the fuzziness,reflect decision-maker＇s psychology,which will help us with the study on information retrieval technology.
