To effectively reconfigure General Bill of Material, reconfiguration process of GBOM based on data-mining was proposed. BOM instances were represented by the weighted unordered tree graph generally, and the algorithm of similarity measurement between two similar BOM instances were presented based on the minimum weighted symmetric difference. In terms of the results of the similarity measurement, all the typical BOM instances were clustered based on the k-Means clustering method.

为有效地重构新型的通用物料清单，提出了基于数据挖掘的通用物料清单重构过程，运用赋权无序树形图表示产品物料清单实例，基于最小赋权对称相异度给出了相似物料清单实例之间的相似度度量算法；基于物料清单实例之间的相似度度量结果，采用k-Means聚类方法对物料清单实例进行聚类。

The average interspecies genetic distance was 0.213. Thrips individuals of the same species were successfully clustered by NJ tree.

Into the F0 contour. And based on the idea of optimization, this paper inversely extracts the parameters associated with optimization (namely the top-line, the bottom-line, the smoothness, the distortion, the stress) from the clustered F0 contour using the MMSE principle for the monosyllable, the disyllable, the trisyllable chunks.

基于这种优化思想，该文针对聚类后的单音节、二音节和三音节韵律块的基频曲线，利用最小均方误差准则通过反演提取了各个单元的优化相关参数(高音线、低音线、平滑因子、形状失真度、重音强度)。
