If there is one thing most people take for granted, it is food. U.S. supermarkets are always well stocked, and we don’t think much about how all that food gets there. When pushed to consider it, I wager most of us assume there are huge warehouses somewhere filled with enough food to feed the nation for some unknown period of time.
The truth is, as a nation, we have little to no warehousing backup for the event of a supply shortage. Our concentrated supermarket supply system uses a technology known as JIT (just-in-time), a method made possible by computers and the internet.
