How to open and close the queue input/output every 30 sec?

Dear all,

I am doing a transportation traffic road simulation with flexsim 6.0 version.

i have created the 5 sources representing 5 different vehicles and connect them to the queue (for the vehicles can go to random port) and then 2 same direction conveyors and finally sink.

Now i wish to the vehicles can pass through the queue every 30 sec, which means that 30 sec allow the car pass through and stop the car for another 30 sec. But i do not know how to do and i have limited knowledge on programming code.

Great thanks
kevin

Hi,

this looks like you should use Messages to Close and open the Output of your Queue. You also will need a Counter or a request to find out if your ports are open or closed.

In the attached model I did the following:

On reset I´m sending two Messages (OnReset Trigger Queue). The first one with a delay of 30s and a Parameter 1. The second message has a delay of 60s and a Parameter 2.
In the Message Trigger I´m closing/ opening the outputport depending on the Parameter. This you could do with pick Options. What you couldn´t do with pick Options was to send another message of of the messagetrigger to repeat this function. Thatswhy I added the last line of query in the script. From here I´m sending a message with a delay of 60s that repeats the Parameter.
