模糊数字的数字特征包括乐观价值,悲观价值,期望的价值,和变化。我们主要基于可靠措施提供模糊数字的几个数字特征的计算公式。特别,对称的模糊数字的变化被提出,并且为模糊数字的变化的超级界限是 presented.Meanwhile,相对可靠的一些结论测量,乐观、悲观的价值也被给。
The numerical characteristics of fuzzy numbers include the optimistic value, pessimistic value, expected value, and the variance. We mainly provide the calculation formulae of several numerical characteristics of fuzzy numbers based on credibility measure. Especially, the variance of symmetric fuzzy numbers is formulated, and a super bound for the variance of fuzzy numbers is presented. Meanwhile, some conclusions relative to credibility measure, optimistic and pessimistic values are also given.
