People module, avoid collision for people waiting elevators

[ FlexSim 19.1.1 ]

Hello,

I am using Flexsim 19.1.1 with the people module, A* and an elevator bank. When people are waiting for the lift in front of the elevator bank, they are all on the same position (they all overlap), so that we cannot see how many people are actually waiting for the lift. This is not convenient when presenting the model to clients and it also make the heatmap less accurate.

Could you please let me know how to avoid this ? I tried to activate the collision detection in the A* but it does not work

Thank you very much for your help,

Kind regards

Aurelien

You could possibly create a waiting line that they would have to pass through first in before entering the elevator and then if the elevator wasn't available they would be waiting in line rather than stacking within themselves.

Could you attach your model so that we can better help you?

Dear @Zac H,

Have you had the opportunity to look at the model please, it's becoming quite urgent please ? One of the project goal is to evaluate if the floor space in front of the elevator is sufficient, therefor a waiting line would not help, people don't queue to wait lift.

Thank you for your help,

Regards

Aurélien

Hi @Aurélien FR,

There are two options that might allow you to gather the data you need about space in front of the elevator.

1) Zac suggested moving the people into a waiting area. This could be done with a queue, so that you can see the people being stacked up in front of the elevator. It would be good visually, but not any better than it is now in terms of getting data for analysis.

2) You could measure the potential space in front of the elevator, measure how much space (on average) a person takes up, and then create a label value on the elevator that tracks available space. For example, if the elevator has 35 sq. ft. in front of it, make a label with a value of 35. Then, if a person takes up 3 sq. ft. on average, you can have each person that "waits" at the elevator detract 3 from 35. From there, you can create alarms for when space hits 0 or even graph the "space" (in sq. ft.) over time.

Hopefully this helps give you some direction! Let us know what specific questions you have.
