基于“收益—风险”的课时分配模型

根据选定组合分配课时风险的一个上界值,使学生总体知识掌握率达到最大的原则,建立课时分配问题的线性规划模型.然后通过分析整理闽清第二中学高三第一学期理科班质量检查考试成绩,带入上述线性规划模型,并运用单纯形法求解带有参数的线性规划问题,从而得出组合分配课时的风险控制值与相应的组合分配课时的成绩最大提升率及课时分配比例向量的关系.

Class Assignment Model which Based on "Income - Risk"

According to an upper bound value of the selected combination of the risk of the allocation hours,students can master the overall knowledge to the maximum rate.We can establish the linear programming model of the class distribution.By analysing the mark of the quality inspection examination of the first semester of science class,grade three,No.2 school in Minqing.We can bring it into the linear programming model,and apply the simplex method for solving linear programming problems with parameters,so we can educe the cost of risk control of the class allocated and the largest increase rate of the relevant combination& allocation of class hours and the relation of distribution of proportional vector.
