RE: [plcs-dex] Representation of scrap

All,

A product_as_scrapped entity type sounds a little too domain-specific to be standardized in the modules. Reference data makes more sense to me – “scrapped” is just one kind of “disposed of”.

Cheers,

David

The option that comes to my mind is to use product assembly structure to link together the two or more "scrapped" product_as_realized bits to the product_as_realized original. The constituent links would have dates that reflect when the original was broken. The original would have the same date to reflect the breaking. I do not think that breaking destroys the identity of the original part. If glue can put the parts back together then the temporary existence of two parts might be considered to be of no business significance and those parts need never be given an identity.

Cheers,
Tim.

Hi
Sean has raised the following issue against: Capability (C045): representing_product_as_realized

Issue: SMB-1 by Sean Barker (04-06-23) minor_technical issue
Resolution: Accept. Status: open
How are scrap items to be designated? (I would suspect that merely classifying them as "scrap" would be unsafe, and would not cope with items broken in two.)

I think that there are two ways of addressing this. Either by classification, or adding the entity "product_as_scrapped" to the product_as_individual module.

In other words, modifying the EXPRESS to

ENTITY Product_as_individual
ABSTRACT SUPERTYPE OF (ONEOF (Product_as_planned,
Product_as_realized,
Product_as_scrapped))
SUBTYPE OF (Product_version);
END_ENTITY;

ENTITY Product_as_planned
SUBTYPE OF (Product_as_individual);
END_ENTITY;

ENTITY Product_planned_to_realized;
realized_product : Product_as_realized;
scrapped_product : Product_as_scrapped;
END_ENTITY;

We may want a different term to scrapped.

Any views?
Regards
Rob
