I have a system that starts a undecided number of similar processes (P) at different times, before terminating its activity. Some of these processes will overlap and some will end before others.
How do I indicate an undecided number of processes in an activity diagram like this:

            O
____________|_____________
     |             |
    (P)           (P)
     |             |
_____|_____________|______
            |
            O

O: start/end,
(P): process,
__: and-split/join

Here are only two processes, but I need lots of them and without writing them all out explicitly.

好吧，这就是我最终得到的解决方案。并行模式下的扩展区域。文本是瑞典文，但相关的是不言自明的。此处第 6 节详细描述了扩展区域。

也许解决方案是创建一个活动分区，它将引用一个属性（具有 0..* 基数），并包含我们的流程，但我不是 100% 确定这就是你的意思......
