作业车间调度问题的析取图

Question

有人能帮我在 TikZ 中绘制以下图表吗？

我从这样的事情开始：

\begin{tikzpicture}[  ->,  >=Stealth,  shorten >=1pt,  auto,  node distance=2cm,  thick,  main node/.style={circle,draw,font=\sffamily\Large\bfseries}  ]

  % Nodes
  \node[main node] (b) at (0,0) {b};
  
  \node[main node] (7) at (2,2) {7};
  \node[main node] (4) at (2,0) {4};
  \node[main node] (1) at (2,-2) {1};
  
  \node[main node] (8) at (4,2) {8};
  \node[main node] (5) at (4,0) {5};
  \node[main node] (2) at (4,-2) {2};
  
  \node[main node] (9) at (6,2) {9};
  \node[main node] (6) at (6,0) {6};
  \node[main node] (3) at (6,-2) {3};

  \node[main node] (e) at (8,0) {e};

  % Solid edges
  \draw (b) -- (1);
  \draw (b) -- (4);
  \draw (b) -- (7);
  
  \draw (1) -- (4);
  \draw (2) -- (5);
  \draw (3) -- (6);
  
  \draw (4) -- (7);
  \draw (5) -- (8);
  \draw (6) -- (9);
  
  \draw (7) -- (e);
  \draw (8) -- (e);
  \draw (9) -- (e);

  % Dashed edges
  \draw[dashed] (1) -- (8);
  \draw[dashed] (8) -- (1);
  \draw[dashed] (2) -- (3);
  
  \draw[dashed] (4) -- (5);
  \draw[dashed] (5) -- (6);
  
  \draw[dashed] (7) -- (8);
  \draw[dashed] (8) -- (9);
  
\end{tikzpicture}

但按照现有文档完成它非常耗时。谢谢（图片中看到的细箭头可以画成虚线，如代码片段所示）。

Answer 1

从这里开始放置节点并将它们与两个循环中的值连接起来。

为此，该chains库有助于以规则的方式放置和连接节点。它们的距离通过 给出node distance。

该0节点放置在节点 1/3 和 1/4 西侧中间左侧，以便垂直居中放置。

graph最后，我通过语法/库在现有节点之间添加了一些简单的连接。
