Default random tasks


I am a new flexsim user. I need some helps for my model. I have some problems that i want to ask.

My model has 10 queues and 10 processors. My source creates task executers flow items. I want every task executers go to 5 queues randomly. I attached my model.

Thank you all...

If I understand you correctly you would like each individual task executor to visit 5 queues/processors then enter the sink?

If this is the case the following should be a simple solution:

Connect the output ports of all of the processors to the input ports of all of the queues.

Create a label on the flow items to track how many queues they have visited (incremented on all queues on entry trigger).

Create a flow rule for each processor that looks at the label to see how many queues have been visited/are left to visit. If all queues have been visited it returns the port that connects to the sink, otherwise it will return a random port from the others available. This will be easier if you always connect the sink as the last output port.

If it is important that the same flow item does not enter the same queue twice then you will need to add some extra logic to track where they have been and ensure they do not select these again.

Hope that helps!
