基于SAS系统的体能测试时间安排模型研究

The Optimization on Arrangements of Time Based on Mathematical Models on SAS Physical Fitness Test

基于不同的考虑,给出了体能测试安排的3个模型.模型Ⅰ,对体能测试的5个项目依据随机服务系统理论,得到每名学生测试完成的平均等待时间;模型Ⅱ,根据SAS系统Proc Univariate过程,得出体能测试班级人数的茎叶图及所有班级的一个分组,给出了各班参加体能测试的具体时问安排表;模型Ⅲ,给出了一个台阶测试与班级人数的关系式,并基于此关系式得出较精确的体能测试时间安排表.基于三个体能测试模型,给出了一种较符合实际的体能测试方案.

This papers gives three mathematical models of physical fitness test based on he difference of considerations： Model Ⅰ, according to the random service system theory, the average waiting time of each student to complete the 5 testing projects is gived; Model Ⅱ, according to the Proc Univariate process in SAS system, we get the stern-and-leaf display of the number of classes in the test, divide the classes into step test and class size is gibed in accordance with the necessary conditions of physicM fitness test, then a more precise schedule of physical fitness test is gived based on this relationship. Based on the three models above, a practical method on arrangements of physical fitness test is gived.
