Different item type is in queue wait until empty

Hi,

I'm in need of some assistance on how to program my processor to only handle one item type at a time. Meaning that if the processor is currently processing 10 of item type 1, then it needs to finish those 10 before it can start processing 10 of item type 2. The processor is not a batch processor but instead sequential.

I have added setup time if item type changes.

The items is created at a certain time, 250 of item type 1, then 250 of item type 2, then 250 of item type 3

Software Version:

FlexSim 23.0.1

I am currently testing the solution, I'm new to Flexsim, so it is taking abit of time :)

Pull the same item type and for each successful pull increment a counter. When the counter reaches the batch size, change the item type for the next pull.

On Exit trigger leaving item is still counted as a content.

Hi Jason,

first of all thank you for the response :) I have tried now since your response to implement your proposal. I can now conclude that I have not been able to implement it.

Is it possible that you could expand and guide me how to implement. I can attach the model, I'm not very experience in mapping the flow in the process flow mode, but using the modules instead.

@NicolaiNielsen , Jason‘s answer is totally a suggestion of 3D modeling. Object property > Input pane > activate PULL > Pull Requirement by item type or label value > the value is himself a label value driven by a label value (a) in your processor

On Exit trigger increment a counter label at your processor by -1. If a batch is finished, then you change the Type of (a) to pull a different kind. And you reset counter label.
