| 中文摘要: |
| 针对三元区间数距离计算中存在的问题，提出一种改进三元区间数距离公式的多属性决策TOPSIS模型。根据三元区间数的确定性和不确定性特点，用基于加权区间值的三元区间数距离代替三元区间数型TOPSIS模型中的欧氏距离，并以此计算三元区间数相对贴近度，按照三元区间数相对贴近度排序决策。通过一个边坡支护方案评价的例子计算分析，并与用其他方法得到的结果进行了对比，说明了方案的有效性。 |

| Aiming at the problems existing in the calculation of ternary interval number distance, a multi-attribute decisionmaking TOPSIS Model Based on improved ternary interval number distance formula is proposed. According to the certainty and uncertainty characteristics of ternary interval number, the model uses the ternary interval number distance based on weighted interval value to replace the Euclidean distance in ternary interval number TOPSIS model, calculates the relative closeness of ternary interval number, and makes decisions according to the relative closeness of ternary interval number. An example of slope support scheme evaluation is calculated and analyzed, and compared with the results obtained by other methods to illustrate the effectiveness of this method. |
