how to move transporter based on order and using FIFO method

Creator

Hello,

I want to ask about how to move transporter based on order. So there is order from customer. Then based on the order transporter retrieve the product from the rack. But the produk that is retrieved using FIFO. The first product that store in rack is the first that is oit. How is the method? I hqve tried bit there is eror.

I do wait for the answer

Thank you

Hi Ginalusiana,

 

for the modeling you create a Movable Unit (MU) with two custom attributes:

ProductName (datatype string) and the ManufacturingDate (datatype datetime).

 

You register an incoming product in the entrance control of the Rank.

For this purpose you use a Tablefile (maybe called Inventory) with two columns with the corresponding datatypes.

This Tablefile is used for your delivery strategy, like FIFO. 

You use the methods sort and find of theTablefile.

 

A second aspect of the question could be: 

Depending on the ordered ProductName a Transporter is sent to an object Rank

which is the storage location of the ProductName: This can be done by the Transporter attribute Destination

 

You need a sensor with the destination at the Track of the Transporter.

You use the attribute Stopped of the Transporter and move of the MU.

Peter

Thank you for your reply,

anyway I did not understand some of those. Can you give me an example?

 

Actually, for my model now I use queue file for FIFO. This is the model.

Hi Ginalusiana,

 

firstly I prepared the arrival process. The selection of the Stores is at random.

 

Please note that you must treat the case that all stores are full.

I recommend stopping the simulation.

 

Do the warehouses contain only one or multiple type?

What is the purpose of the Queues? Maybe a storage management.

 

Then I suggest a shape for the track for the Transporter.

Your tracks will require changes of the driving direction (forwards/backwards).

The Transporter must not enter the stores.

 

Regards,

Peter

Thank you for your example,

 

well I would like to explain my model. My objective here to compare the order picking of randomized storage and class based storage.

 

The model that i sent tou you is randomized storage. 

First the product store to storage randomly. After that, there is order and the transporter have to retrieve the product based on the order in right time and right number. The transporter here is like forklift. the transporter only one and its capacity is one entity. The method for retrieving product is FIFO. That's why I use queuefile to know the posistion of first product that come in. So the transporter will know the posistion of the product.

But i stuck that i dont know the method and syntax and the programing to retrieve the product. I dont have any idea and this is for my last project for thursday. T.T

 

Please help me 

 

Thank you

Please help me or do you have another way that more simple?

How a retrieve order for the Transporter is defined?

It is only the product name, like "EnzyplxTab50"?

Maybe the sequence of transport orders isgiven as an input parameter.

Is that right?

So I make tablefile_order that consists of when, what, and how many the product must retrieve. But it has to retrieve based on fifo.
That's it.
how I make it?

How a retrieve order for the Transporter is defined?

So the transporter must retrieve the product based on tablefile_order. in that table,there is datetime when the product have to ship, what the product is, and how many palet of product have to retrieve. To take the product, transporter must retrieve using FIFO. for example in tablefile_order, the first order is "Obical, 8 entities, and retrieve 2015/01/06". So the transporter must take that product which is the 8 obical first come in to storage in January 6th,2015.

 

So how is the method?

Thank you 

 

here I attach my model

Hello Ginalusiana,


Most of requirements have been met.
You see that the disposition of the orders is according to FIFO

The controlling the Transporter by the sensor controls is an interesting example.

It is a challenge to manage multiple Transporters.

Peter
