线性规划是运筹学的一个重要分支,也是近几年高考命题的热点,它在实际生活中有广泛的应用。但在实际教学中,受教材教学先后顺序的限制,要求我们在教学过程中,必须有一些创新,在创新的过程中还不能丢失数学的思想。本人在教学中利用数形结合思想,借助数轴上数的大小特点,通过平移方法寻找可行域内最左(右)的点,从而得到线性目标函数的最值。 Linear programming is an important branch of operations research, but also the hot topic of college entrance examination in recent years, it has a wide range of applications in real life. However, in practical teaching, the order of teaching materials is limited, which requires that we must have some innovations in the process of teaching, and we can not lose the idea of ​​mathematics in the process of innovation. I teach in the use of mathematical combination of ideas, with the size of the number of axes on the number of features, through the translation method to find the feasible leftmost (right) point, so as to get the most value of the linear objective function.
