As an aside, I've worked at Flora Holland, the company (a cooperative owned by a hundred and then some growers) that orchestrates a lot of the logistics; the clip in the article with the carts is a small part of their transit halls. They start in the early morning with the flowers and plants coming out of cold storage and auction them off early on; before midday, the halls are quiet and empty again, hundreds if not thousands of trucks full of carts and containers having been filled and sent off by then. Each and every day.
Besides the actual shipping of plants etc, one of their major logistical challenges is managing the hundreds of thousands of iron carts (pallet sized) and millions of plastic containers (where they put the actual flowers in), those all have codes and deposits to manage, and every day they have to calculate how many they need. (same with how many temps they need, they can vary the amount of people they employ by hundreds if not thousands per day. Highest amounts are around valentine's day and mother's day).
Software-wise it's also interesting. I can't mention much about their current day development, but one factoid is for example the auction hall itself. It's a Dutch auction (see wikipedia), so response times is crucial. It turns out that the exact position you're sitting in that hall already has an effect on the response time and whether you win or lose an auction. They tried to put it on the internet as well so the buyers could do it from home, but they couldn't solve the latency problem (at least not to the satisfaction of the buyers).
Nowadays though, less and less is sold via the auction, and less and less actually passes through the main venue; there's a lot more orders in advance (like shops ordering roses a year in advance for valentine's day), and there's a lot more direct grower-to-customer traffic.
