摘要
重新定义了广义模糊数,引入了"序"、"运算"及"度量",得到了一些基本性质,并研究了广义模糊数序列的极限及性质,给出了单调收敛、闭区间套等重要定理,使模糊数对应理论得以拓广.
In the paper,the generalized fuzzy number is redefined,the order,operations and metrics are induced on it,some basic properties are obtained.The limit and properties of sequences of generalized fuzzy numbers are discussed,some important theorems such as monotone convergence theorems,closed interval set theorem are given,these have make the corresponding theory of fuzzy numbers extend.
