Denver Airport Automated Baggage System Abandoned
cherylchase writes "Denver International Airport opened in 1995 with an ambitious fully automated baggage system: 26 miles of underground track, thousands of small gray carts, all controlled by a mainframe programmed for just in time delivery. But the system never worked well; bugs delayed the airport's opening for months (at $1M/day). The system has now been abandoned as a cost cutting measure." From the article: "Technology, too, has brought change. Back then, the big-brained mainframe doing it all from command central was the model of high tech. Today the very idea of it sounds like a cold-war-era relic, engineers say. Decentralization and mobile computing technology have taken over just about everything, allowing airlines, warehouse operators and shippers like FedEx to learn with just a few clicks the whereabouts of an item in motion, a feature that was supposed to be a chief strength of the baggage system."
This was on the world news (well nightly network news) almost 3 weeks ago, bleck.
Also, they mentioned that this system was the first one run by PCs! Wikipedia has had this up for quite some time as well.
Reading up on it, it appears more that the lack of PLANNING was more at fault. The system was designed AND implemented with only 2 years left before opening, and with the majority of construction on the airport already completed, meaning the physical aspects of it had to be squeezed in where ever spae was available, given that, the results are not to surprising.
If anything this represents a massive failure on the part of management to allocate enough time for a project, implementations of far smaller systems than the one at Denver spent two years alone in just the research phase!

I did a google search on Denver Airport baggage system and found this: classic case of bad software design.
95% of all sigs are made up.
Not mentioned much these days was that the huge delays in getting the Denver Airport baggage handling system was a huge black eye to IBM who had been bragging loudly about how their OS/2 operating system was running it.
The BAE design includes a number of high-tech components. It calls for 300 486-class computers distributed in eight control rooms, a Raima Corp. database running on a Netframe Systems fault-tolerant NF250 server, a high-speed fiber-optic ethernet network, 14 million feet of wiring, 56 laser arrays, 400 frequency readers, 22 miles of track, 6 miles of conveyor belts, 3,100 standard telecars, 450 oversized telecars, 10,000 motors, and 92 PLCs to control motors and track switches.
Let's make some educated guesses here. How many PCs? 300? Good grief! Later in the article it says the PCs were running OS/2. So what? This is just bad architecture, regardless of OS. So many parts, so many points of potential failure. And the NetFrame Systems "fault tolerant" server is simply...a glorified PC. (It's X86, ~300 MHz P2, and likely running Windows NT, according to other sources.) This article has more on the sad fate of NetFrame.
There's nothing even close to a mainframe computer in this baggage handling system. The New York Times sucks again!
