摘要
给出了折线模糊数的定义及其有序表示,并结合两个具体例子讨论了折线模糊数与其有序表示的对应关系.提出了折线模糊数的重心定位计算公式及其指标排序准则,并通过实例验证了折线模糊数排序方法的有效性.
The definition of polygonal fuzzy number and its ordered expression are given and the corresponding relationship between polygonal fuzzy number and its ordered expression is discussed through two specific examples. The calculation formulas of the centroid positioning of polygonal fuzzy number and the criterion of the index ranking are put forward. The effectiveness of the ordering method of polygonal fuzzy numbers is verified through a practical example.
