在科学技术、经济管理中常常要按一定的标准(相似程度或亲疏关系)进行分类。例如,根据生物的某些性状可对生物分类,根据土壤的性质可对土壤分类等。对所研究的事物按一定标准进行分类的数学方法称为聚类分析,它是多元统计“物以类聚”的一种分类方法。由于科学技术、经济管理中的分类界限往往不分明,因此采用模糊聚类方法通常比较符合实际。(In science and technology, economic management, often according to certain criteria (similarity or closeness) classification. For example, according to some biological traits may be of biological classification, according to the nature of the soil on soil classification can be. Studies on the classification of things according to certain standards of mathematics known as cluster analysis, it is a multi-Statistics " Like attracts like" a classification. As science and technology, economic management in the classification boundaries are often not clear, so the fuzzy clustering methods are usually more realistic.)
