如何利用单纯形表上的信息

本文分析了求解线性规划的基本方法－－单纯形法所使用的单纯形表，将表中所提供的信息分为直接信息和间接信息两类，论述了如何充分利用这些信息的方法。例如如何由最终表求原问题、如何利用表中的数据互相推演和校正等。这是一篇教学经验的总结，对初学者可能有一定的帮助。

How to Use the Information in Simplex Tableau

In the paper, the basic method, simplex method with simplex tableau, used for solving linear programming problem is analized. As the result, the information in a simplex tableau can be grouped into direct and indirect information, and then the approach how to use the information is developed. As examples, how the original problem of a linear programming can be recovered from its final simplex tableau, and how the data in the tableau can be deduced or corrected by each other with the approach are showed. The paper is the summary of author's teaching experiment and may be helpful for the leamer in the field.
