1、首先,我们分析调查到的数据,发现学生流符合泊松分布,服务时间符合指数分布,由此我们的模型就变成了排队论中典型的MM
模型,根据MM
模型中的各效率指标的公式,我们可得到学一食堂拥挤情况的各方面数据。
2、根据模型求解得到的数据,我们对模型进行了更精确的量化分析。我们发现,解决本模型的关键就在于分析顾客平均排队时间,我们对其与窗口数之间的关系进行了拟合,并就两者之间关系进行了灵敏度分析。
3、针对窗口数与顾客平均排队时间之间的关系,我们从经济学的角度进行了分析,即比较增加窗口后成本的增加量与减少排队等待时间所带来的收益之间的大小关系。

用递归的方法实现以下算法:
1.以二叉链表表示二叉树,建立一棵二叉树(算法5.3);
2.输出二叉树的中序遍历结果(算法5.1);
3.输出二叉树的前序遍历结果(见讲稿);
4.输出二叉树的后序遍历结果(见讲稿);
5.计算二叉树的深度(算法5.5);
6.统计二叉树的结点个数(算法5.6);
7.统计二叉树的叶结点个数;
8.统计二叉树的度为1的结点个数;
9.输出二叉树中从每个叶子结点到根结点的路径。(The following algorithm is implemented using a recursive method:
1., the two fork list is used to represent the two fork tree, and a two fork tree is established (algorithm 5.3).
2. output two order tree traversal results (algorithm 5.1);
3. output two prefix traversal results (see lecture notes);
4. output the result of traversal traversal of two fork tree (see lecture notes).
5. calculate the depth of the two forked tree (algorithm 5.5);
6. statistics the number of nodes of the two fork tree (algorithm 5.6).
7. statistics of the number of leaf nodes of the two forked tree;
8. the number of nodes of the two forked tree is 1.
9. output the path from each leaf node to the root node in the two fork tree.)
