For the first two choices, a single sequential execution path results, while the choice of Task 3 and Task 4 results in both branches executing in parallel.

对于前两个选择，将只导致一条后续执行路径，而同时选择Task 3和Task 4将导致并行执行这两个分支。

To make the model more simple, a method based on the network vector graph has been proposed, which don't differentiate the choice structure and parallel structure in the design interface.

本文提出了一种基于有向网络图的建模方法，不在模型表面区分选择结构与并行结构，简化了建模过程。
