Picking process

Hi guys,

I need to model a picking process in a warehouse (lets say 20 different racks, 10 operators). Each operator take a cart and a picking order , walk through a network node and stop at each rack from which he need to pick items.

I want to simulate a one day picking based on a picking list (Order number, Racks reference, number of items to pick per rack).

I’m thinking about this modeling approach:
A source creates items “cart” with a label table “Order” created and based on a Global table “Picking list”, than creates a tasksequence based on the label table “Order”.

Is this a good approach to model this case ? Is there a simpler approach ?
Did somebody model this kind of process?

Thanks for ur help.

Here's a sample model I built that uses a very efficient way to model this kind of situation in Flexsim. It is also a good sample of how to interface your model with Excel as you can import the Global Table data using the MTEI.

It uses a custom task sequence to send the pickers to the destinations and delay, but doesn't actually use flowitems in the rack. Rather, it uses values in Global Tables to represent the inventory levels.

The code and theory behind the model is quite simple and elegant. The most complicated part of this model is the stats that are collected.

very nice model thank you Phil, I'm looking into it and I'll ask some questions if needed...

I recently had to update this model to Flexsim v5.1 for a user, so I thought I'd share with all WarehousePickingDemo.zip

hello:

I want to simulate the order picking problem in the model.
I've refer the model, then I try to build the model.
Because I do not need the same length rack, so I use the Queue instead of the rack.
But I meet some problem, in InQueue trigger.

here is my model. thank you..

I've find the problem

Hi Cliff,

I have a few questions regarding the model you shared previously.

1) How did the stock appear on the rack without a source?

2) How is the stock named as per the Sku?

I have looked around in the model and have been unable to find answers to the question above.

Thank you,
Vin Low

Please take a look into the user event "UpdateTables" ( Tools > User Events ). You should look also into Global Tables, Global Variables, User Commands and Flowitem Bin.

Greetings

Carsten

hello guys, how I can download it the wharehouse picking file? I try of download but this is impossible for me, only show me a blank page.

Thank's in advance

I don't remember if it is your expectation.

I attach the warehouse order and picking demo.

Regards.
