摘　　要：首先定义了区间数贴近度,并讨论了相应的性质;然后在联系数的基础上定义了区间型联系数及运算法则,并给出了区间型决策矩阵的规范化公式,提出了一种基于区间型联系数相对贴近度的决策方案排序方法.运用该方法进行多指标决策和评价,概念清楚、涵义明确,决策和评价结果准确、可信、不具有主观随意性.最后通过实例分析验证了该方法的有效性和实用性.Firstly,the interval number similarity degree is defined and its quality is given.Then this paper takes the definition of interval connection number based on connection number,and discusses the corresponding operation principles.Some formulas for normalizing the decision matrix with interval numbers are given.A priority method,based on relative similarity degree of interval connection number,for the uncertain multi-attribute decision-making problem is also proposed.Using the new method to make decision,the exact and reliable evaluation results without subjectivity can be reached.Besides,the new method also has explicit concepts and a wide range of applications.Finally,an illustrative example is given to demonstrate the feasibility and practicability of the proposed method.
