Pulling strategy

[joey_s]

[ FlexSim 19.0.2 ]

Hello everyone.

I have the logic that I want to create a model.

1) I want to pull the list out of the queue 1-4 and Queuetotal. The pull strategy will choose to pull the nearest queue before each item and the number of pull in each work cycle is in the form of statistical distribution

2)I want the truck to pick up items in QueueOut by the time it comes to pick up, but each round is different in the statistical distribution model And the capacity of the truck, but the loading times will depend on the number of items pulled to QueueOut.pull1.fsm

Thank you.

Hi @joey

Which parts do you need help with in part 1?

And in part 2:

What do you want the model to do by the time the truck comes to pick up the items?

What is different on the statistical distribution? The amount of items it picks up? The time between pickups?

How will the loading time correspond to the number of items?

The Process Flow Tutorials should be able to give you all the information you need to program that logic into your model.

Hi @Braydn T

I need help from both parts. I want the truck to work when an order occurs where the order of each item is item 1, exponential statistical distribution and item 2, lognormal statistical distribution.

The amount of items drawn is that I want to be in the statistical distribution format, such as item 1, exponential statistical distribution and item 2, lognormal2 statistical distribution.

(The time between pickups? How will the loading time correspond to the number of items?

The truck will load the goods from the transporter. The loading time of the truck will wait until the amount of items pull in each time is complete.)

I hope I can explain to you what I want to communicate.

Thank you.

Hi @joey

This can be accomplished easily with Process Flow. Make an event triggered source for items arriving in the pickup queue, batch them to the right amount that you want to pick up, and then run a subflow with a load task and a delay for the statistical distribution you want.

The Process Flow Tutorials should be able to give you all the information you need to program that logic into your model.

Was Braydn's answer here helpful to you? Do you have any more questions on this we can help you with?

@Joseph Gillespie

I studied in the tutorial process that he suggested, but I still can't create the logical model that I want.

I'd like to help you with your question, though you'll have to help me understand a few things you're trying to do:

When you say you want to pull the list out of the queue 1-4 and Queuetotal, what do you mean? Are you saying that you want Queuetotal to be a member of the "Queues" list?

When you say the pull strategy will pull the nearest queue, what do you want the queue nearest to?

You said in your comment to Braydn that you want the truck to work when an order occurs. What do you mean by "order" in your model?

The more clearly you explain what you are looking for, the better answer we can get you.

Hi @Joseph Gillespie

Yes, I want Queuetotal to be a member of the Queues list.And when the transporter will go to receive item the Queues It will select the nearest queue first.

An overview of the logic that I want is toten from "INTER-ARRIVAL SOURCE"(1 token from Source PF = 1 truck). It will order the truck to wait at one point and when the amount of item types to pull along the truck will travel to "Queue Out" the truck will wait to load items from transporter.

The next station is when there are trucks waiting and items in Queues, along with the transporter traveling to receive items at Queues from the nearest queue to pull the list out to QueueOut and load the items onto the truck the transporter will process one item at a time until the required amount (item 1 = 5, item 2 = 10) and when the truck receives the full amount of this item, the truck will travel to the sink.

I hope I can communicate for you to understand.

Thanks.

From what I understand so far, you want to have a list that includes Queues 1-4 and "Queue total", and then you want the Out Transporters to pull queues from the list. When do you want them to pull queues? Only when they are full? Only when they have some items in them?

And once a transporter has pulled a queue you want the number of items they pick up from the queue to follow a statistical distribution right?
