Well, Overproduction is a problem when you make big batches and then need to store them. A lot of "inputs" outside of food production can be stockpiled reasonably longer, so without breaking with JIT/Lean philosophy all you need to do is to create a bigger buffer at the start of the value chain, which might mean that missing X deliveries won't stop your production rate instead of 1 missing delivery stopping the whole factory.
