Control restricted area in conveyor system with decision points

I would like to have multiple decision points. When an item crosses one, I would like the others to control items from crossing them. All these decision points are on different conveyors.

Software Version:

FlexSim 16.0.1

It sounds like you are trying to use decision points to define a section of your conveyor system where only one item should cross at a time.

Here are two example of how to do that:

Acquire and Release Area Pickoptions in On Arrival Triggers

This model uses the Acquire Area pickoption in the On Arrival triggers of decision points that represent the start of the restricted area and the Release Area pickoption in the On Arrival triggers of the decision points that represent the end of the restricted area.

You can find more information on these pickoptions in Help > User Manual > Conveyors > Pick List Behaviors > Area Restriction.

Process Flow with a Zone

This model uses Process Flow to listen to the On Arrival of the various decision points. It uses a Zone to restrict access to one item at a time.

Thanks @regan.blackett for the models!
