setup time in processor when item type changes

Hello everybody,

I have several items and a processor in my model.

The operation that I want to do is that the item comes into the processor and it will be setup during a time which depends of its Type. And I am using the option "setup If Item Type Changes (values are set)". It works perfectly for the second or third and go on items but not for the first item that come into the processor, when the first item arrives, it has not setup time and I dont know how can I fix it.

Is there any suggestion?

Thank for your attention.

@Sara W2

Here's an example model that might work for you: processorsetuptime.fsm

I set the Setup Time in the processor to "Values By Case" and had the Setup Time depend on the type of the item:

Hope this helps!

Hi Joseph,

This option is not suitable to my case, I am seeing that this makes my system does setup to each item. I am sorry If I had not explained well my issue, I have a lot of items of several types, and my setup time should take place only once for each type when items come into the processor, it is not necessary make a setup for each item, only to the first item. Therefore, there is not setup time for the rest of items of the same type that follow.

And, thank you for your attention.

@Sara W2

If I understand correctly, you would like the processor to only have a setup time for the first of each item type? Would you like the setup time to still be different based on type?

@Sara W2

Also, you said that "setup If Item Type Changes" worked perfectly for you besides the first item.

Are you saying that you want a setup time every time the type changes or just the first time you encounter a certain item type?

Hi @Joseph Gillespie, if I have more than one processors, is it possible to start with the setup time once they have finished processing one type of item or they necessarily need to wait until receiving the new type of item to start their setup time?

For example, it the setup time is 200 seconds in all the processors when a change of items occurs and the time of processing of the first Processor is 100 seconds, the second Processor stay 300 seconds without doing anything instead of using this time to do their setup and to be ready to start processing the item when the item arrives to it.

Thank you!
