Finally, I don't think any of those are good solution.
When I think about this subject, I see two kind of way:
- static value (current implementation) where the company don't want
to receive product at all (because it can not manage it).
- non-static value where the company wants to optimise the shipment
and warehouse cost. But this one can not be managed correctly by
static rules because such optimisation will depend on many
parameters like: sale frequency, quantities, stock quantities,
supplier delivery cost etc.
So this are too much parameter to be computed on the fly which
means this optimisation should be done by a background process
which will update the static value for the period until the next
run.
