our customer, in some manufacturing processes, produces a certain quantity of waste.
Sometimes, for particular processes, he can reuse the waste as input material to produce the next batch.
In this case the workers mix a part of waste with the new input materials.
Technical department has to communicate to manufacturing department what the maximum percentage of input material that can be substituted by waste material is.
In their previous PLM system, they use to communicate this quantity insering the finished good both as output material and as input material in the same recipe.
In this way, when they associated a quantity (in kg or in %) to the input row containing the finished good, the purpose is to show that "this is the maximum quantity of waste material that can be reused".
How can we manage that in Agile?
There are two things that may help you with this use case:
1. You can model the "waste" as an referenced output product or an internal output. Either of these types will allow you to use it in a formulation step. To maintain formulation balance I would recommend a referenced output product.
2. You can also turn on the range calculation paths. With these calculation paths a min and max percentage field will be available for every formulation input. This will allow you to set a max percentage value. To turn on formulation ranges use the following configuration keys. Once they are turned on you will see new range calculation paths in the formulation path drop down.
- this will turn on min and max percentages while the input percent field is editable
- this will turn on min and max percentages while the input quantity field is editable
- this will turn on min and max percentages while the input yield quantity field is editable
You can learn more about how to manage feature configurations in the configuration guide.
thank you for your answer.
I'm still wondering: if I set up an output as waste external (and this means that the system will create an associated material specification, isnt it?), then I can use the waste output as input in the same formulation?
The system prohibits users from using waste as an input into a formulation or a finished good. If it is truly waste then it's waste and is disposed of. If its just waste for that specific process but used again in other formulations then we consider that a product. If its just waste for that specific process but then sold as a finished good we consider that a by-product.
