How can I generate the flowitems from the source like this?

I could like to generate the flowitems from the source like this:

I want the flowitems ( some Boxes) with the different quantity, itemtype and color for each arrival. The Inter- arrival time for the flowitems could follow weibull distribution.

More important, How can I get the same sequence of the flowitems in second time simulation when I reseted the model after first simulation.
( that means, i wanna get the same sequence of the flowitems for each simulation)

( I am a very new users of flexsim) Please give kind advice and hits.
Thank you very much

Source:
You could use Arrival Schedule in the Source. Setting color and Itemtypes are standard functions in Triggers.
To learn more about this, try to do Toturials;-)

Repeating Statistics:
In the Statistics Tab you got the option "Repeat Randoms Streams". Turning this on will repeats all statistic distributions in your model.
As far as I know, it´s not possible to turn it on for only one object.

Thank you for your repley.

I understand Arrival Schedule can set those parameter and set color, Itemtypes in triggers - onCreation

however, if i want to generate the flowitem in weibull distribution, and each time the source can generate 10- 15 flowitems with same itemtype and color, Then next arrival time will generate other 10- 15 flowitems with same itemtype and color. I know Arrival Schedule can set it, but how can make it follow weibull distribution without setting a arrival time.
(The source should generate a set of flowitems follow weibull distribution for each day)

Also, for weibull distribution, what is the meaning of (0, 1, 2, 0) ?
I found the repeat random steams, thank you

This sounds a little more difficult.

Setting Itemtype:
You can set the Itemtype at any point in your model. This means you even could do it in a Queue or somewhere else.


Weibull distribution:
Here you should have a look at the Commands describtion, you can find in Flexsim Help. Think it´s very well explained there.

For your Problem:
I understood it the way, you want to create 10 - 15 Items with same color and Itemtype. Then changing both.
I would set the Weibull distribution in Inter- Arrivaltime option.
Further create three Labels on this Source called "TargetCounter", "Counter" and "NewItemType". If your Itemtype really should change every 10 - 15 you will need another distribution here and some Query.

Attached an example Model. This only works for the first 4 Itemtypes. For more you should think about the logic to color items. Tried to explain what I´ve done in the Triggers.

A more simpler approach would be to use a source with an interarrival time using the weibull distribution and after the source use a separator with a splitting quantity of duniform(10,15). On the exittrigger of the separator you can set any label, itemtype etc. You can use getinput() function to determine which batch you are using.

Thanks Steven,
this even would be much easier. But I understood it the way, that the single items should arrive by weibull distribution!?

Don´t got easier ways in mind. Maybe anybody else?

Is it possible to release Items with weibull distribution out of Seperator?

You could place a processor behind the separator and have a weibull as a processtime maybe.

Thanks Steven,
so there is an easy solution without programming.

Now the source can create 10 - 15 Items with same color and Itemtype. Then changing both. It is similar what I want.

if I want to create 10 - 15 Items with same color and Itemtype at the same time ( not one by one), then changing both for next time, is it possible?

Thank for your reply!

This would be Stevens solution with Seperator. For this you only need 1 Item from Source and Seperator creates 10 - 15.

Can you attach a simply model for me to better understanding?

I have tried to build, but not success

Think this may help!?
Wish you much luck.
