创建一个 tikz 图形

Question

我正在尝试为我的论文创建一个 tikz 图形。我完全是 tikz 新手，找不到可以修改为如下样例：

对于您能提供的任何帮助我都会非常感激。

我的基本开始是这里的代码示例：

\usetikzlibrary{calc,trees,positioning,arrows,chains,shapes.geometric,%
    decorations.pathreplacing,decorations.pathmorphing,shapes,%
    matrix,shapes.symbols}

\tikzset{
>=stealth',
  punktchain/.style={
    rectangle, 
    rounded corners, 
    % fill=black!10,
    draw=black, very thick,
    text width=10em, 
    minimum height=3em, 
    text centered, 
    on chain},
  line/.style={draw, thick, <-},
  element/.style={
    tape,
    top color=white,
    bottom color=blue!50!black!60!,
    minimum width=8em,
    draw=blue!40!black!90, very thick,
    text width=10em, 
    minimum height=3.5em, 
    text centered, 
    on chain},
  every join/.style={->, thick,shorten >=1pt},
  decoration={brace},
  tuborg/.style={decorate},
  tubnode/.style={midway, right=2pt},
}
\begin{tikzpicture}
  [node distance=.8cm,
  start chain=going below,]
     \node[punktchain, join] (Goal) {Goal};
     \node[punktchain, join] (Inventory Analysis)      {Inventory Analysis};
     \node[punktchain, join] (Impact Assesment)      {Impact Assesmen};
     \node[punktchain, join] (Interpretation) {Interpretation};
  \end{tikzpicture}

像这样：

\documentclass[tikz,
               border=3mm,
               preview]{standalone}
\usetikzlibrary{arrows,
                calc,chains,
                decorations.pathreplacing,decorations.pathmorphing,
                fit,
                positioning,}
\usepackage{paralist}

    \begin{document}
\tikzset{
  line/.style={draw, thick, <-},
        }
\begin{tikzpicture}[
node distance = 8mm,
  start chain = A going below,

    PC/.style = {%PunktChain
        rectangle, rounded corners,
        draw=black, very thick,

        on chain},
                    ]

        node[PC, minimum height=\n1,
