在 TeX 中生成系统环境图？

Question 1

答案是热情的，是的! 有很多选项可用，包括

tikZ（在这个网站上非常受欢迎，你可能很快就会看到解决方案）
PSTricks（示例如下）

下面的代码使用了该pst-node包，详细信息请参阅文档。

控制车辆驱动 mk1

\documentclass{article}

\usepackage{pst-node}

\begin{document}

\begin{pspicture}(0,0)(10,10)
 %\psgrid % useful during construction
 % draw the main nodes
 \cnodeput[shadow=true](5,5){control}{\begin{tabular}{c}Control\\Carpark\\(System)\end{tabular}}
  \rput(2,8){\rnode{vehicle}{\psshadowbox{Vehicle}}}
  \rput(8,2){\rnode{driver}{\psshadowbox{Driver}}}
  % connections from vehicle to control
  \nccurve[angleA=-90,angleB=180,linestyle=dashed,arrows=->]{vehicle}{control}
  \ncput*{Entry}
  \nccurve[angleA=-45,angleB=145,linestyle=dashed,arrows=->]{vehicle}{control}
  \ncput*{Arrival}
  \nccurve[angleA=0,angleB=125,linestyle=dashed,arrows=->]{vehicle}{control}
  \ncput*{Exit}
  % connections from drive to control
  \ncdiag[armA=2cm,armB=1cm,linearc=0.5,angleA=25,angleB=0,arrows=<->]{driver}{control}
  \ncput*{Paid-ticket}
  \nccurve[angleA=45,angleB=-15,arrows=<-]{driver}{control}
  \ncput*{Ticket}
  \nccurve[angleA=180,angleB=-90,arrows=->]{driver}{control}
  \ncput*{Issued-Ticket}
  \nccurve[angleA=135,angleB=-45,arrows=->,linestyle=dashed]{driver}{control}
  \ncput*{Request}
  % arrows
  \psnode(1,1){S}{}
  \psnode(1,3){N}{}
  \ncline[arrows=->,linestyle=dashed]{S}{N}
  \ncput*{Control Flow}
  \psnode(1,4){S1}{}
  \psnode(1,6){N1}{}
  \ncline[arrows=->]{S1}{N1}
  \ncput*{Data Flow}
\end{pspicture}

\end{document}

如果你以前没有使用过PSTricks，有几件事不需要注意。使用以下命令编译代码：

latex myfile.tex
dvips myfile.dvi
ps2pdf myfile.ps

或者

xelatex myfile.tex

如果您要使用pdflatex，则使您的序言看起来如下：

\documentclass{article}

\usepackage[pdf]{pstricks}
\usepackage{pst-node}

\begin{document}
....

然后你可以运行

pdflatex -shell-escape myfile.tex

编辑

这是另一个版本，比我的原版稍微好一点（恕我直言）；它使用\ncarc而不是\nccurve

控制车辆驱动 mk2

\documentclass{article}

\usepackage{pst-node}

\begin{document}

\begin{pspicture}(0,0)(10,10)
 %\psgrid % useful during construction
 % draw the main nodes
 \cnodeput[shadow=true](5,5){control}{\begin{tabular}{c}Control\\Carpark\\(System)\end{tabular}}
  \rput(2,8){\rnode{vehicle}{\psshadowbox{Vehicle}}}
  \rput(8,2){\rnode{driver}{\psshadowbox{Driver}}}
  % connections from vehicle to control
  \ncarc[arcangle=-45,linestyle=dashed,arrows=->]{vehicle}{control}
  \ncput*{Entry}
  \ncarc[linestyle=dashed,arrows=->]{vehicle}{control}
  \ncput*{Arrival}
  \ncarc[arcangle=45,linestyle=dashed,arrows=->]{vehicle}{control}
  \ncput*{Exit}
  % connections from drive to control
  \ncarc[ncurv=1,arcangle=-90,arrows=<->]{driver}{control}
  \ncput*{Paid-ticket}
  \ncarc[arcangle=-25,arrows=<->]{driver}{control}
  \ncput*{Payment}
  \ncarc[ncurv=0.75,arcangle=-60,arrows=<-]{driver}{control}
  \ncput*{Ticket}
  \ncarc[arcangle=45,arrows=->]{driver}{control}
  \ncput*{Issued-Ticket}
  \ncarc[arrows=->,linestyle=dashed]{driver}{control}
  \ncput*{Request}
  % arrows
  \psnode(1,1){S}{}
  \psnode(1,3){N}{}
  \ncline[arrows=->,linestyle=dashed]{S}{N}
  \ncput*{Control Flow}
  \psnode(1,4){S1}{}
  \psnode(1,6){N1}{}
  \ncline[arrows=->]{S1}{N1}
  \ncput*{Data Flow}
\end{pspicture}

\end{document}
