摘要
本文应用系统工程理论,结合灰色趋势关联度,研究了灰色趋势关联系统及数学模型。作为该模型的应用,提出了灰色趋势关联聚类预测方法。以深成份指数为样本对各类行业进行了聚类分析,得到了一种符合实际的聚类预测结果,阐明了灰色趋势关联聚类预测方法的有效性、方便性和实用性。
Based the gray trend relational degree and systems engineering theory, the model of gray trend relational system is investigated. As an application of this model, the gray trend clustering method is presented. Taking the Shenzhen component stock index as the sample, various industries are clustered by gray trend clustering method, and the clustering result accords with index wave fact. It shows that the gray trend clustering foeeast method is valid, convenient and practical.
