Kann mir jemand helfen, dieses Flussdiagramm in LaTeX zu erstellen?

Question

Was ich bisher getan habe, ist bei weitem nicht das, was ich will:

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\usepackage{mathtools}
\usepackage{ifthen}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}



\begin{document}
%Flow diagram Node Definitions
\tikzstyle{prof} = [rectangle, rounded corners, minimum width=2cm,     minimum height=0.5cm,text centered,text width=8em, draw=black, fill=red!30]
\tikzstyle{process} = [rectangle, minimum width=3cm, minimum height=1cm, text centered, text width=15em, draw=black, fill=green!30]
\tikzstyle{arrow} = [->, >=latex', shorten >=1pt, thick]
\tikzstyle{cloud} = [draw, ellipse,fill=red!20, node distance=2cm,minimum width=2.5cm, minimum height=2em, align=center]
\tikzstyle{cfr} = [rectangle, rounded corners, minimum width=3cm, minimum height=1cm,text centered,text width=15em, draw=black, fill=blue!40]
\tikzstyle{cbr} = [rectangle, rounded corners, minimum width=3cm, minimum height=1cm,text width=15em,text centered, draw=black, fill=blue!40]
\tikzstyle{hyb} = [rectangle, rounded corners, minimum width=4cm, minimum height=1cm,text width=25em, text centered, draw=black, fill=green!30]


\begin{figure}
\begin{center}
\begin{tikzpicture}[node distance=2cm]


\node (bt) [cfr] {Phase 7};
\node (pp) [cbr, right of=bt, xshift=8.5cm] {Phase 1};
\node (newuser) [cfr, below of=bt,yshift=-2.5cm, xshift=-3cm] {Phase 2};
\node (olduser) [cbr, below of=pp,yshift=-2.5cm, xshift=2cm] {Phase 3};
\node (dm) [cbr, below of=bt, yshift=-7cm] {Phase 4};
\node (dmo) [cbr, below of=pp, yshift=-7cm] {Phase 5};
\node (ver) [cloud, below of=bt, yshift=-2.5cm, xshift=5cm] {Phase 6};

\end{tikzpicture}
\caption{Process Flow}

\end{center}
\end{figure}

Answer 1

Ich bezweifle wirklich, dass Sie diesen Code erstellt haben, um dieses Bild zu zeichnen, da es keinen Sinn ergibt, eine Reihe von Stilen zu erstellen, die Sie nie verwenden, mit einer veralteten Syntax und Farben, die Sie nicht möchten. (Deshalb frage ich mich, ob der Code wirklich aus einer nicht angegebenen Quelle stammt.)

Es gibt Pakete für Flussdiagramme, die Sie sich am besten einmal näher ansehen sollten.

\documentclass[border=10pt]{standalone}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes.arrows,arrows.meta,positioning,shapes.geometric}

\begin{document}
\begin{tikzpicture}
  [
    node distance=2cm,
    >=Latex,
    cbr/.style={text centered, draw=black, minimum height=1cm, rounded corners, minimum width=3cm, text width=15em, },
  ]
  \begin{scope}[local bounding box=c]
    \draw (-.5,-.75) coordinate (a) [out=-30, in=120] to (.5,-.75) |- (-.5,.75) coordinate [midway] (b) -- cycle ;
    \clip  (a) |- (b) -- ++(0,1) -- ++(-2,0) |- cycle ;
    \begin{scope}[shift=(135:.25)]
      \draw (-.5,-.75) coordinate (a1) [out=-30, in=120] to (.5,-.75) |- (-.5,.75) coordinate [midway] (b1) -- cycle ;
    \end{scope}
    \clip  (a1) |- (b1) -- ++(0,1) -- ++(-2,0) |- cycle ;
    \begin{scope}[shift=(135:.5)]
      \draw (-.5,-.75) coordinate (a2) [out=-30, in=120] to (.5,-.75) |- (-.5,.75) coordinate [midway] (b2) -- cycle ;
    \end{scope}
  \end{scope}
  \foreach \i [count=\j] in {60,120,...,360}
  {
    \node (p\j) [cbr] at (\i:7) {Phase \j};
    \draw [<->] (p\j) -- (c);
  }
  \foreach \i/\j [remember=\i as \ilast (initially 6) ] in {1,...,6}
  {
    \pgfmathor{\i==1}{\i==4}\ifnum\pgfmathresult=1\draw  [<->, densely dotted] (p\ilast) |- (p\i);
    \else\pgfmathor{\i==2}{\i==5}\ifnum\pgfmathresult=1\draw  [<->, densely dotted] (p\ilast) -- (p\i);
    \else\draw [<->, densely dotted] (p\ilast) -| (p\i);
    \fi\fi
  }
  \node (w) [right=of p6, double arrow, draw, text width=20mm, text centered] {Arrow};
  \node [right=of w, draw, cylinder, shape border rotate=90,  anchor=center, minimum width=15mm, minimum height=30mm] {Drum};
