People Collision

Hello community,

we have a similar question to the ones already asked in the “Collision of People” or “Understanding of preempting and collision”- thread. Since we were not able to reproduce the same behaviour in a test model, we decided to explain it with the help of a GIF. As you can see in the GIF, there is a female and a male person who cross each other´s paths. The male person leaving a kiosk in the left picture frame; the female person leaving a waiting line in the right picture frame, heading to that same kiosk. Since their ways cross, the male person pushes the female person away (along his path) and away from her “forecasted” path. Like in our test files, we would have expected the two persons turning away from each other, “making space” and then going ahead to their destinations. But this is not the case, unfortunately. People are controlled by a process flow. Do you have an idea how to handle this? Best regards!

Hi @Nip J

Could you post the model that you took this GIF from? As the collision we are seeing is not a normal case scenario it would help to see the simulation and better be able to find out what is happening?

Hi,

unfortunately, we are not supposed to upload the model, neither could we reproduce the above mentioned behaviour in a simpler model to upload. We worked around that behaviour by sending the patients to other locations first, to reduce crossing paths. Nevertheless, we cannot exclude that this behaviour does happen somewhere else in the model´s system. But thanks for responding so quickly.

Hi @Nip J,

It's hard to know how to help further without looking at your model. To receive a more accurate solution, please post your model or a sample model that demonstrates your question.

Proprietary models can be posted as a private question visible only to FlexSim U.S. support staff. You can also contact your local FlexSim distributor for phone or email help.
