how to set a "setup time" only for first item

[ FlexSim 18.2.0 ]

Hello everyone, I already made a model with a "setup time" only for the first piece with process flow and I think I did it in a complicated way.

Is there a simpler way to do it? maybe with 3D or process flow

I attach the model

Since the Processor already has a Setup Time function, I would just use the built-in feature, but change the time to 0 after the first time. I did this by putting a piece of conditional code in the Setup Time field:

getoutput(current) ? 0 : 15

That code returns 15 when the output of the processor is 0 (i.e the first time) and then returns a 0 whenever the output is not 0 (every time after).

@Matthew Gillespie

thank you, and I managed to do it, your answer was very useful another question, how could I set a "set up time" for the first item, according to the item.Type?

I did this, although it seems that I am doing it in a general way, could you help me to do it for the item. Type?

I attach the model, thank you

I'm not sure what you're asking. Are either of these interpretations correct?

1. The very first item should have a setup time and no other items should. The setup time for that first item should vary based off the item type of the first item.

2. The first time an item with a certain item type is processed the processor should do a setup time for that item. For example:

Item	Type	Setup Time
1	1	5
2	1	0
3	2	10
4	1	0
5	2	0
6	3	7
