帮助改善我的网络

Question

我写了以下代码：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{arrows.meta,decorations.pathmorphing,backgrounds,positioning,fit,petri}

\begin{document}
\begin{tikzpicture}

[place/.style={circle,draw,thick,inner sep=0pt,minimum size=6mm},transition/.style={rectangle,draw,thick,inner sep=0pt,minimum size=4mm}]

\node[place]      (c1)      at (-3,6)  {};
\node[place]      (c2)      at (0,6)   {};
\node[place]      (c3)      at (0,3)   {};
\node[place]      (c4)      at (1.5,2)   {};
\node[place]      (c5)      at (-1.5,2)   {};
\node[place]      (c6)      at (0,0)   {};
\node[place]      (c7)      at (-3,1)  {};
\node[place]      (c8)      at (2,1)  {};
\node[place]      (c9)      at (-2,0) {};
\node[place]      (c10)     at (-2,-4) {};
\node[place]      (c11)     at (-2,-8) {};
\node[place]      (c12)     at (2,-4)  {};
\node[place]      (c13)     at (2,-8)  {};
\node[transition] (r1)      at (-1,1)  {};
\node[transition] (r2)      at (1,1)  {};
\node[transition] (r3)      at (1,4.5)  {};
\node[transition] (r4)      at (-1,4.5)  {};
\node[transition] (r5)      at (-3,4.5)  {};
\node[transition] (r6)      at (-3,2)  {};
\node[transition] (r7)      at (-1,-2)  {};
\node[transition] (r8)      at (-2,-6) {};
\node[transition] (r9)      at (1,-2)  {};
\node[transition] (r10)     at (2,-6)  {};

\draw [->,thick] (c11) to (r8);
\draw [->,thick] (c10) to (r8);
\draw [->,thick] (c12) to (r10);
\draw [->,thick] (c13) to (r10);
\draw [->,thick] (r8)  to [bend right=45] (c10);
\draw [->,thick] (r10)  to [bend left=45] (c12);
\draw [->,thick] (r7) to (c10);
\draw [->,thick] (r9) to (c12);
\draw [->,thick] (c6) to (r7);
\draw [->,thick] (c6) to (r9);
\draw [->,thick] (c1) to (r5);
\draw [->,thick] (r5) to (c3);
\draw [->,thick] (r4) to (c3);
\draw [->,thick] (c3) to (r3);
\draw [->,thick] (r3) to (c2);
\draw [->,thick] (c2) to (r4);
\draw [->,thick] (c3) to (r1);
\draw [->,thick] (c3) to (r2);
\draw [->,thick] (r1) to (c6);
\draw [->,thick] (r2) to (c6);
\draw [->,thick] (c9) to [bend right=45] (r7);
\draw [->,thick] (r7) to [bend right=45] (c9);
\draw [->,thick] (c7) to (r6);
\draw [->,thick] (r6) to [bend right=45] (c5);
\draw [->,thick] (c5) to [bend right=45] (r6);
\draw [->,thick] (c7) to [bend right=45] (r1);
\draw [->,thick] (r1) to [bend right=45] (c7);
\draw [->,thick] (r2) to [bend right=45] (c8);
\draw [->,thick] (c8) to [bend right=45] (r2);
\draw [->,thick] (c4) to [bend right=45] (r2);
\draw [->,thick] (r2) to [bend right=45] (c4);
\draw [->,thick] (r1) to (c5);

\end{tikzpicture}
\end{document}

结果是：

我怎样才能通过这种方式改进它：

为了使圆圈的颜色和大小、箭头的尖端以及矩形的形状和颜色如下图所示（我不需要所有矩形都是垂直的，有些是垂直的，有些是水平的）：

Answer 1

我做了一些调整来回答你的问题。当然，你稍后应该再次微调定位。

改编

• 删除选项前的空行tikzpicture
• 添加, minimum size=9mm, draw=blue!50, fill=blue!20​place/.style
• 定义transitionh（水平）和transitionv（垂直）minimum width并minimum height设置
• 改变箭头尖>=latex
• 删除了未使用的 tikzlibraries：decorations.pathmorphing,backgrounds,fit
• 您可以插入多个令牌，使用tokens=1等等。

建议

• 我离开positioning那里，因为我建议使用它进行相对定位而不是绝对定位。
• 看看pgf/tikz 手册第 64 章“Petri-Net 绘图库”（有一些很好的例子）。

结果
