Queue -weight limiting

hi

I am having some problem to complete my example model. Here each of the item has weight value as label. after process it will go to queue and i wanted to setup of a weight carrying limit for the queue.

1. I have added currentweight to count total weight , when it will be >=12 , the output will open and transporter will move all the items. But after first transportation finish , how i can reset the value of currentweight in the Queue ?

2. and how i can tell the transporter that when the simulation end (no more items to come) even if the weight is below 12 , transport all of them.


Please help

1. onexit of the queue, either subtract the weight everytime an item leaves or make the your label 0 when the last one leaves (content(current) == 1, because the in the exit trigger the item is still in the queue)

2. You don't tell the transporter but you tell the queue to release all items by sending a message (probably a delayed message) to the queue when the last one is processed and on this message you open the output.

ok i fix my 1st problem

Can you kindly give me more hints about the code for sending message ?

i mean what can be the code actually for using senddelayedmessage in my model now? i was looking the manual also,.. cant get it properly. please anyone help?

Suppose you know on your processor when your last product (in this case your 100th) has been processed then you can state something like:

if( getoutput(current) == 100 ) {
  senddelayedmessage( outobject( current, 1 ), 0.1, current, 1, 0, 0);
}

Assumed is that the queue is connected to the first output port of the processor

and on the onmessage of your queue you could write

if( msgparam(1) == 1) openoutput(current);

THANKS !

so the first code will be in Processors ONExit Triggers ?
and if i have more than 1 processors will this code remain the same ?

also dont understand why u said "(in this case your 100th)"

yes as long as your queue is the first output port of the processor.
But considering your questions have you worked your way through the tutorials?
And might I suggest to follow a basic training somewhere

yap.. i look through some tutorials also. but not become the expert yet

if( getoutput(current) == 100 ) ; here by 100 you are meaning the number of item get out from the process ? so it should not be 15 ? as i have 15 items to come.

I tried with putting the first code OnExit trigger of Processor and second code Onmessage trigger of Queue ! but still not working..

Thanks again for your time !
