a Sorter

[Pier]

Hi, would it be possible to see an example of a sorter system? Say you have a warehouse (WH) with some incoming doors for trucks carrying goods (A) and out going doors for leaving trucks (B) on the other side of the WH.
The goods are unloaded from the A's and, through a conveyor sent to a sorter which distributes the items amongst the trucks (B) waiting on the other side of the warehouse. Is there a good way of modeling this or shall I model each possible branch at each door as a proc testing an attribute of the simEntity travelling on the conveyor?

(you can tell I am a new user of Jaamsim right?)
thanks
Pier

Pier,

I've built a prototype version of your warehouse model with EntityContainers to represent trucks and SimEntities to represent the individual goods. A working version of the model is attached to this post.

Unfortunately, the prototype model lacks a key feature -- the ability to load only the selected goods onto the departing trucks. To model this properly, I need to add a new keyword to the AddTo object (representing the truck loader) that will specify the type of goods to be loaded. The new keyword will tie in with the Match keyword for Queue.

The new keyword will be included with next week's release (2015-19) and I will provide an updated model at that time.

Dear Harry. Thanks for your help. I will start playing with this. You are very very kind and really helpful.

Pier,

Here is the full model for the Warehouse that I promised -- see attached. I've used the new Match keyword introduced in JaamSim 2015-19 to specify which entities are loaded onto the trucks by the TruckLoadingStation object.

If you run the model long enough, you will notice that the queue of trucks and the warehouse inventory both grow without bound. I thought that this was a mistake at first, but in fact the modelled Warehouse inventory for each product is similar to a random walk so increasingly large inventories can be expected. This behaviour is probably obvious to Industrial Engineers, but it caught me by surprise.
