摘要
根据模糊聚类的基本原理以及传递闭包法、模糊相似矩阵和模糊等价矩阵等算法,选取了7个相对有效的评价指标对我国7个具有代表性省份的建筑业发展水平进行了分析,在不同水平下得到相应的模糊等价矩阵。利用模糊等价矩阵对我国7个省的建筑业发展水平进行模糊聚类,并使用MATLAB软件编程得出聚类结果,根据聚类结果对各省的建筑业发展水平进行了纵向和横向的比较分析。
According to the basic principles of fuzzy clustering, transitive closure method, fuzzy similar matrix and fuzzy equivalent matrix methods, this paper analyzed development levels of construction industry in seven provinces based on seven relatively effective indexes and reaches corresponding fuzzy equivalent matrix. It carried out fuzzy clustering for the development levels using fuzzy equivalent matrix and got clustering results based on MATLAB software. Finally, vertical and horizontal comparatively analysis were conduct for construction industry development level in seven provinces.
