The revised simplex method is used at first to calculate the optimal line extensions without integer constraints of the variables so that it can be determined which lines should be constructed.

第一步不考虑变量的整数约束，用修正单纯形法求解，由此可确定一部分线路是否需要建设。第二步在缩小的可选线路范围内进行整数规划计算，从而快速形成电网发展方案。

Here, using the mathematica software and the outcome of the computation , we can see which interval is better easily. In chapter 2, the author firstly studies three two-stage simultaneous confidence intervals for the pairwise treatments with the same precision and reliability in a balance one-way classification model ,then work out the optimal sample size of the first stage by numerial computation.

第2章作者讨论了平衡单向分类模型中，成对效应对照的三种两步同时置信区间，接着在保证三种区间可靠度和精度相同的情况下，利用数值计算的方法对最优第一步抽样量及平均抽样次数进行比较。
