Census Vs Time Chart for predefined Zones

Hi all,

To generate a Census vs Time Chart for predefined zones in the model (General environment), please refer to the attached model created by @Jason Lightfoot.

floorzoneexample.fsm

@Jason Lightfoot In the repeat interval, I have noticed that when a person passes through a zone in a time less than the repeat interval (currently the repeating Interval is 10, meaning 10 minutes?), the chart fails to capture that data. However, when I decrease the repeat interval in the Static Collector, it captures more passings. Can you confirm if my assumption is correct?

For example, if an operator passes a door in a second or less with Reapeting Interval 10 it won't capture it on the chart.

Yes - it was just to capture snapshots at periodic intervals as you described in the other post. You could sample more frequently and we could optimize the code if the zones are non-overlapping ( to remove operators already found in a zone).

The idea of having non-overlapping zones sounds great.

I've been thinking about how to group different zones into one larger zone, but in FlexSim, it doesn't seem possible to create irregular shapes, like the one in the picture below. Any thoughts or ideas on this?

So with data and relationships you can do anything. All you need for that is, instead of having the zone object as the identifier you have a label on the object denoting the zone and use a map to keep at track of the count by label value. The stats collector would need modifying to enumerate the label values rather than the zone objects.

It's slightly curious to me that you endorse the non-overlapping areas and then show an image that has them overlapping.

@Jason Lightfoot

If we attach a label to the operator for tracking the 'Zone,' what type of map can monitor the 'Zone' values?

When it comes to overlapping zones, I was thinking about two different ideas:

  • First, we can implement non-overlapping zones to prevent the operator from being counted again if they have already been included in a specific zone.
  • Second, we can consider the opposite concept, where we utilize overlapping zones, much like the example I've presented earlier, to aggregate the counts of operators across all of those intersecting zones.
