框图子节点

Question

我只是想用 LaTeX 制作任何框图，但我遇到了一个麻烦，我不知道如何制作节点的子节点，

我想要的只是将名为“Antrian”的框移动到红色位置，并将其下方的两个框作为其子节点。

\documentclass{article}
\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows, arrows.meta, calc, positioning}
\begin{document}
    \pagestyle{empty}

    % Define block styles
    \tikzstyle{block} = [rectangle, draw, 
    text width=22mm, text centered, rounded corners, minimum height=4em]
    \tikzstyle{line} = [draw, -latex']


    \begin{tikzpicture}[node distance = 2cm, auto]
    % Place nodes
    \node [block] (operasional) {Operasional};
    \node [block, right of=operasional, node distance = 3cm] (proses) {Proses};

    \node[block, right of= proses, node distance = 3cm] (antrian){Antrian};
    \node[block, below of= antrian] (kasir){Jumlah kasir yang beroperasi};
    \node[block, right of=kasir, node distance = 3cm](kedatangan){Rata-rata tingkat kedatangan};
    \coordinate[below = of $(kasir.south)!0.5!(kedatangan.south)$](temp1);
    \node[block, below of = temp1, node distance =3cm] (kinerja) {Kinerja};
    \node[block,left of= kinerja, node distance = 3cm](pelayanan){Pelayanan yang optimal};

    % Draw edges
    \path [line] (operasional) -- (proses);
    \path[line] (proses) -- (antrian);
    \path [line] (antrian.south) -| (kasir);
    \path [line] (antrian.south) -| (kedatangan);
    \path [line] (kinerja) -- (pelayanan);
    \draw   (kasir.south) |- (temp1) -| (kedatangan);
    \draw[-Latex]   (temp1) -- (kinerja);
\end{tikzpicture}
\end{document}

我真的需要你的帮助，非常感谢

欢迎使用 TeX.SE！您正在加载但未使用positioning。我也\tikzstyle用相应的\tikzset语法替换了。

\documentclass{article}
\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows, arrows.meta, calc, positioning}
\begin{document}
    \pagestyle{empty}

    % Define block styles
    \tikzset{block/.style={rectangle, draw, 
    text width=22mm, text centered, rounded corners, minimum height=4em},
    line/.style={draw, -latex'}}


    \begin{tikzpicture}[node distance = 1.5cm, auto]
    % Place nodes
    \node [block] (operasional) {Operasional};
    \node [block, right=of operasional] (proses) {Proses};

    \node[block, right=of  proses] (antrian){Antrian};
    \node[block, below left=of  antrian] (kasir){Jumlah kasir yang beroperasi};
    \node[block, below right=of antrian](kedatangan){Rata-rata tingkat kedatangan};
    \coordinate[below = of $(kasir.south)!0.5!(kedatangan.south)$](temp1);
    \node[block, below of = temp1, node distance =3cm] (kinerja) {Kinerja};
    \node[block,left=of  kinerja](pelayanan){Pelayanan yang optimal};

    % Draw edges
    \path [line] (operasional) -- (proses);
    \path[line] (proses) -- (antrian);
    \path [line] (antrian.south) -- ++(0,-0.5) -| (kasir);
    \path [line] (antrian.south) -- ++(0,-0.5) -| (kedatangan);
    \path [line] (kinerja) -- (pelayanan);
    \draw   (kasir.south) |- (temp1) -| (kedatangan);
    \draw[-Latex]   (temp1) -- (kinerja);
\end{tikzpicture}
\end{document}
