Do you want to execute one process multiple times? If so, you do not need to copy the same process X-times or execute it X-times, you simply can alter the “Number of cycles” in the Edit process window.

Further, if your algorithm will converge onto a single result, you can check the "Loop while something changes only" box and set the number of cycles to infinite. The cycle will then end, when a result is reached. 

A nice algorithm that you might want to test multiple cycles on is the “Pixel-based Object resizing” algorithm. However, you can use it for all! Enjoy!
