摘要
为了深入研究中场球员的跑位对比赛胜负的影响，提出了基于因子分析的评价方法。该方法通过解析比赛日志文件，建立因子分析模型，并计算双方中场球员跑位的综合评价得分。实验结果表明，该方法所推测出的球队排名与近几年RoboCup仿真比赛的排名大致吻合，并且通过对综合评价得分与比赛胜负得分差绘制散点图，可以发现，综合评价得分较大的球队获胜的概率也较大。理论结合实际后得出，对中场球员活动的区域来说，本方中场侧翼位置的跑位对比赛胜负的影响最大。
In order to study the influence of the midfielders＇ positioning for the matches＇ result, a method based on factor analysis was put forward to evaluate the midfielders＇ positioning. This method constructs mathematics model through parsing the log files of the games ,and calculate comprehensive evaluation scores of the midfielders＇ positioning for each team. The experimental result indicates that the team＇s rankings which were inferred using this method are coincide with the result rankings of the RoboCup simulation 2D games in recent years, and through drawing the scatter diagram of the relevance between comprehensive evaluation scores and result of the match, it could find that the team which has a higher comprehensive evaluation score would have a triumph with a great probability. After integrating theory with practice, it indicates that the key of the match is midfield flanks＇ positioning ofmidfielders in their own half for midfielder＇s active area.
