摘要: 用模糊贴近度方法获取模糊类, 在模糊类中通过封装的模糊规则描述属性之间的关系, 根据模糊贴近度和模糊范围定义了用于计算子类和超类、 对象和类之间的隶属函数, 解决了对不精确和不确定复杂信息的获取问题, 所得结果可用于不精确需求建模.

关键词: 模糊贴近度, 模糊类, 不精确需求

Abstract: Fuzzy class can be obtained via fuzzy relevance degrees approach. The relationships among the attributes can be described by fuzzy rule s enclosed in the fuzzy class. And the membership functions, which are used to calculate the membership degree of subclass and superclass, and the members hip degree of object and class, are defined according to fuzzy relevance degrees and fuzzy range. Thereby, the problem of imprecise  and uncertain information acquirement can be settled. As a result, this approach can be applied to model ing the imprecise requirement.

Key words: fuzzy relevance degrees, fuzzy class, imprecise requi rement
