Hello All,
Need suggestions on how to model the following scenario
I am working with Yearly volumes of 100 parts being produced in 15 different machines.
Sample MU values: Part A - 800000 and Part B - 100000 parts being planned for whole year
For Part A on Machine A set up needs to be done once every month for a certain setup time value
For Part B on Machine A set up needs to be done every 15 days.
Likewise have for remaining parts with Monthly & Biweekly set up schedule.
Please suggest modeling approaches for the same.
Regards,
Kavitha

You can use the setting SetupAfterNumParts on the Set-up tab. Hence, N=800000/12~66667 parts.
In reality, the set-up/preventive maintenance may be scheduled at specific times or depend on more complicated aspects. But the above setting can already give you the correct number of set-ups per year at about the correct time.

Its a Product Mix which gets loaded in a station.
My input data is organized like this
Part Name Station Annualvolume SetupFrequency Set Up Time
A StationA 800000 Monthly 30 Mins
B StationA 10000 Bi Weekly 45 Mins
C StationA 80000 Bi Weekly 35 Mins
D StationB 100000 Monthly 30 Mins

Yes, but the question is what causes the set-ups. Is there a set-up at the start of each production run of a part?

Yes.

it could work with the setting: Set-up depends on: user defined atttribute
If you check the last set up date of a part type against the simulation time, you can change a user defined attribute, that triggers the set-up (see example entrance control of the singleProc).

In that case the default settings should already work, as long as the MU Names reflect the part names. If you make sure that the proper amounts of your parts pass a station, the correct set-up behavior will result.

Thanks Steffen for the solution.
