论文部分内容阅读
线性规划的内容,多数教材安排是数学模型,图解法,一般标准形,矩阵表示,以矩阵为工具,引入一系列概念,最优解的判定,进一步是单纯形表的结构原理及解题步骤。电大教材也是如此。这个体系系统完整,但是,对电大学生来说,知识的衔接上遇到一个大的跳跃。矩阵写起来简单,用起来抽象。能否避开抽象的矩阵理论,采用计算机便于接受的初等变换或初等的消元法,教材安排上更渐进些,使具有初中程度的学生能通过自学基本掌握这部分内容呢?出于这些想法,根据我们的教学体会和对线性规划课程的认识,对单纯形方法的原理及其写法提出一个设想。
The contents of linear programming, most of the textbook arrangement is mathematical model, graphic method, general standard form, matrix representation, matrix as a tool, the introduction of a series of concepts, the optimal solution to determine the structure of the simplex form and solving steps . TV University teaching material is also true. The system is complete, but for the undergraduates, there is a big jump in the convergence of knowledge. The matrix is simple to write and use abstractly. Can avoid the abstract matrix theory, the use of the computer is easy to accept the elementary transformation or elementary elimination method, textbooks arranged more gradual, so that junior high school students can self-learning basic grasp of this part of the content? From these ideas According to our teaching experience and knowledge of linear programming courses, we put forward a tentative idea of the simplex method and its writing method.
