如何制作一个类似 HTA 的东西？

我正在尝试实现以下目标：

HTA 示例

但是我不知道如何制作这些箭头。我有一些代码可以给出几乎正确的东西，但有些地方很乱，无法自动选择我想要的路径（重叠节点等）

\path [draw, -latex'] (START) |- (DUMMY) |- (DUMMY2) |- (GOAL);

我制作了两个虚拟节点，试图让这个东西遵循我想要的路径，也就是向下、向左、向下，就像上图中的“预热炉”->“准备工厂和服务”步骤一样。

有人能帮我指点如何更好地引导这些路径吗？如果可能的话，不要让额外的节点造成混乱？我目前被困在这个问题上，不知道该怎么办。我在谷歌上搜索了很多，但只得到了部分答案（比如上面的那个）。

答案1

下次，请提供一个最小工作示例，以便人们不必从图像中复制每个单词，而至少可以剪切粘贴文档的基本结构和图表的文本内容。

此解决方案使用forest并自动构建和添加节点开头的标签。为此，我得到了非常快速、准确的帮助Sašo Živanović 的回答致我的关于避免多重标签的问题。

pstricks具有psmatrix环境和相对较短的代码的解决方案：
