摘　　要：影响图是决策问题的图形表示,利用影响图可以有效地解决智能Agent的行为选择,而传球问题就是球员Agent选择传球速度和角度的问题。建立了一个基于影响图的传球模型,并根据该模型创建一个评价传球效果的效用函数;然后利用由教练程序改写的记录员程序来记录数据,并进行统计得到效用函数中的概率值;最后通过训练得到效用函数中系数的值,并利用此效用函数作传球训练。训练结果表明该效用函数是可信的。Influence diagram is a diagram of decision- making, using influence diagrams can solve the behavior choice of intelligence agent effectively, while the question of passing help the agent choose the speed and angle. In this paper, first build a model of passing and a utility function which can evaluate passing decision. Second,data are recorded by recorder program which is recomposed by coach program and then calculate these data to obtain the probability of utility function. In the end, the values of coefficients in utility function gain by training, and then use the utility function to train the team. The training result indicates that the utility function is credible.
