田赛成绩的灰色区间预测方法的研究

The research on method of gray area calculation on field performance

灰色区间预测方法是把运动员的原始成绩划分为上、下限线,根据时间和成绩的二维坐标平面的上、下限线的发展趋势,预测出未来的运动成绩.从而为教练员制定训练计划提供精确信息,也为运动员参加比赛时对对手成绩的了解提供依据.灰色区间预测的方法简单,实用,准确性高.

In this paper, 'gray area calculation' is the mode of the dividing an athlete's original data into up and down limit lines demonstrated on two-dimensional coordinate axes of time and performance so that this future performance can be forecast according to their respective tendency. The findings of such analysis not only provide the coach with accurate information, but they also render the player his competitor's data. While simple and practical, this mode ensures accuracy.
