Operation makes multiple items?

[Christina Arendt]

Hi all, I cannot figure out how to make a single operation make multiple items from one item. We are doing some metal working, rolling foils from an ingot of material. One ingot can make from 2-20 foils at a time, depending on which type of foil we're making. Right now, my "roll [specific] foil" operation is set to only make one foil from one ingot and I can't figure out how to change that so I can specify. We have a very long lead time on purchasing the ingots and primarily want to use frepple for figuring out when to buy them. Thanks!

Hi,

 

I would think you express the consumption of ingots in fractional numbers.
Eg a demand for 1 of foil X requires 0.5 ingots, a demand for 1 of foil Y requires 0.05 ingots, etc…

This will give you a good enough view on the purchasing of ingots.

 

This approach is an approximation. How&which foils can be produced together from a single ingot is not considered in detail.

If you need that level of detail, it’s perfectly possible to create operations that produce multiple items.

You fill the operation-material table as shown below.

We often use such approach to model “by-products” or “scrap material”. When the output is flexible and changes in function of the demand this approach won’t be valid. The approximated approach described first is then the best & simplest approach.

 

operation	item	quantity	type
make foils X and Y	ingot	-1	start
make foils X and Y	X	3	end
make foils X and Y	Y	5	end

 

 

Stay safe,
