运用主成分分析和模糊数学的方法对艺术体操运动员选材的评价体系进行了研究,旨在提供一套适用于中国艺术体操运动员的科学选材综合评价模型和计算机软件工具。首先,我们引入主成分分析法,建立了艺术体操运动员选材评价的指标体系。然后,根据综合评判及多维决策过程中普遍存在的模糊性,在模糊数学的方法指导下,我们建立起多层次模糊综合评价体系模型。最后对该综合体系的可行性及结果的可靠性进行了必要的检验。
The main body of component analysis and fuzzy mathematics are used to evaluate the selection system of rhythmic gymnastics athletes. The aim is to provide a comprehensive scientific evaluation model and computer software tools for Chinese rhythmic gymnastics athletes. First of all, we introduce the principal component analysis method and establish the index system of the selection of art gymnasts. Then, under the guidance of the fuzzy mathematics method, according to the fuzziness in comprehensive evaluation and multidimensional decision-making process, we establish a multi-level fuzzy comprehensive evaluation system model. Finally, the feasibility of the integrated system and the reliability of the results of the necessary tests.
