摘　　要：利用三角模糊数的特点及两个三角模糊数的位置关系,提出了一种计算简便的比较两个三角模糊数大小的满意度公式,实现了两个三角模糊数大小的比较。特别地,对于正规三角模糊数,该满意度公式有更简单的形式。最后,通过几个数值例子,说明了该比较方法的简捷性和有效性。A satisfactory degree function for comparing two triangular fuzzy numbers was presented by using the characteristics of triangular fuzzy number and the position relations between two triangular fuzzy numbers,and then,the comparison of two triangular fuzzy numbers was realized based on the method.Particularly,the satisfactory degree function has a simpler formula for comparing two normal triangular fuzzy numbers.Finally,the simplicity and validity of the comparing method was illustrated through some numerical examples.
