【摘要】 本文利用模糊数学方法,对图书馆工作的几个主要环节,提供了一个比较合理而实用的数学模型。主要的做法是,首先根据教学与科研工作两个中心任务,确定图书建设的指标,然后用[0.1]中的一个非负实数,賦予权数,构造典藏结构表。然后按降半正态分布,给出图书分类的隶属函数,并利用最大隶属原则,确定图书编目的类目。最后定义采购函数为:更多还原

【Abstract】 In this paper, we applied fuzzy sets to the library work, built a feasible fuzzy model for book-storage, classification and purchase. Our main approach as follow: According to the center requirement of teaching work and seientific research, fixed the index of library construction, we construct a table for book-storage by weights using the positive real numbers in [0,1],then the fuzzy decision of classification is made by a grade of membership, and applied the principle of maximal membership determines the class Subject.Finally, the purchase function is given by the formula:更多还原
