Fuzzy综合评判在标枪运动员等级判别中的应用

Application of FCE (Fuzzy Comprehènsion Evaluation) in Grading Javelin Throwers

本文在把Fuzzy综合评判应用于优秀运动员等级判别的过程中,首先将各评判因子分级,统计出评判对象与评判因子等级间的隶属频率;然后建立其Fuzzy关系矩阵,并计算出各因子的权重;最后根据综合评判模型对待判的样品(运动员)进行等级评判。评判结果符合实际情况,效果与逐步判别分析相近;又经回判验证准确率达98.11％。

The FCE method has been used for dividing elite athletes into various grades. The basic procedures include: 1) Grading all under-deliberate elements and preparing statistics on the subordinate frequency between the objects of evaluation and the elements of evaluation; 2) Setting up a fuzzy correlation matrix and calculating the weight of each element; 3) Using the comprehensive evaluation model to grade the samples(athletes). The results conform to facts and are similar to those obtained by the step-by-step evaluation method. They are 98.11% accurate by back evaluation.
