How to send items to Queue based on item type

Thillaiarasu — Thu, 18 Jan 2024 12:15:00 GMT

[ FlexSim 22.2.4 ]

I am a beginner, and I am practicing the Flexsim model.

As a part of my regular practice, using Separator, I am trying to split the incoming item into two items ( Item 1 and Item 2 ) and set the label and color. Then, based on the item type, I would like to send the item Type 1 to Queue 1 and to Queue 2 for Item Type 2

I am having difficulty setting the trigger at the exit; what "value" do I need to select, or am I missing something? I have added my port settings and trigger info for your reference.

Appreciate your help

Regards,

Thillaiarasu

There are two events that can evaluate that there are more items by split mode:

Send to Port
On Exit

if you want to divert items an On Exit event is to late. You have to do it in function "Send To Port" in Output Properties pane.

Unfortunately there aren't any templates that allows you to manipulate labels. You have to write a source code script to assign label values right behind the header of this function source code.

AND you have to choose before you add this code your template, otherwise selecting a new template destroys any previously entered code.

AND this function gets executed for each leaving item once. This means after a first item has left this object any code will evaluate all staying items again. This said there are two scenarios in relation of counted item as staying inside of this object. Items are exiting instantly or items are waiting inside of object because they are transported or are blocked by next object entrance allowance.

forobjecttreeunder(current){ // recursively look for each object subnode at start node
a.Type = a.cnt; // "a" is found object of step 
a.cnt +=1; // intermediate count label at item, can be destroyed on exit
}
item.color = Color.byNumber(item.Type);

cnt label at item must be initialized on Entry with value of 1.

code to destroy label "cnt on exit:

item.attrs.labels.subnodes["cnt"].destroy();

Thanks for the info and answer; I will check this. I am a beginner; can it be done in object mode without code?

@Thillai, split mode in a separator object creates items. Then there are only a few events. And only function "send to port" is able to fetch created items first and tell instantly FlexSim where they must go.

You can set a separator to send items in round robin fashion. And you can set a label value by local variable called "port" on Exit. And you can set by this variable name also colors of leaving objects. This is a functionality where you do not need to write source code. But this is not what you requested to achieve. This result is similar. But it is a more like creating two items from one. You send one to output port one and a second to output port two. When they are leaving you tell them to record the output port number in a label and chooose by this output port number a color. It is more a passiv observation then really actively doing something.

If it's always 50/50 then you can just use round robin for the send to port and set the color and type on exit trigger based on the port. Example model attached.
