一、前言 一切事物间存在着在一定条件下的相似性。人们常常在处理问题时利用这种相似性,它也是“成组技术”的基础。 所谓相似性,是指事物间在某种条件下具有某些相同的特征,它反映了这些事物在某种程度上共同具有人们所关心的某种属性。 所谓相似事物是指这样的一些事物,它们在某种条件下具有某些相同的特征,从而表明它们在某种程度上共同具有人们所关心的某种属性。 事物的相似性是一个模糊的概念。在利用相似性来处理事物时,常常首先要解决对事物的表征问题,也就是根据既定目的,选择表征事物属性的特征指标,从而描述事物的相似性。 本文主要研究特征指标的种类,性质及其定量方式。
I. Preface There is a similarity between all things under certain conditions. People often take advantage of this similarity in dealing with problems, and it is also the basis of “grouping techniques.” The so-called similarity refers to the things under certain conditions have some of the same characteristics, it reflects that these things to some extent in common with people have a particular attribute. The so-called similar things refers to such things, under certain conditions, they have some of the same characteristics, thus indicating that they are to some extent together have a certain attribute of interest. The similarity of things is a vague concept. In the process of using things to deal with things, we must first solve the problem of representation of things, that is, according to the established purpose, choose to characterize the attributes of things to describe the similarity of things. This article mainly studies the type, nature and quantitative way of the characteristic index.
