Love the article.

> The state of the world 30sec after you called your elevator might be very different but the system is unable to adapt. Turns out the loss in flexibility is not worth the extra information for the optimizer.

Very interesting. I am on a 30 flr 8 car today so guess it made sense for Destination Dispatch. It does mean there is rarely a full elevator and usually 3 stops max allowing it to go fast to high floors.

Other things I thought could factor in elevators is shopping trolleys: both customers and trolley collectors. One level will have people coming in with full trolleys and almost always the other levels will not. I don't think elevators really care they just fill up and you need to call another one.

Also prams but they are 2-way.

> What if the nearest car is full? I wonder how do elevators find out if the car is full or not. I once been to an office building where it obviously didn't work properly. I needed to get down from a pretty high (15+) floor to the bottom during the evening rush. The elevator got full immediately but still stopped almost on every floor on the way down. Each time an awkward scene ensued: a huge crowd of people outside…

I guess it could use weight. Since it should also refuse to go if overloaded.

> Not all elevators have buttons in them. Some of the fancy new elevators have a kiosk on each floor that allows you to specify what floor you're heading to before the elevator even arrives. The kiosk then points you to which elevator you should wait for.

I stayed in a hotel with these. It was horrible. Most people didn't figure it out, would get in the wrong elevator, and just get lost in the building.

Oh my god, every time I'm waiting for the elevator, I think of how annoying it must be to be someone who's building the algorithm to make sure that you minimize the amount of wait times between picking up people and taking them to their destination. Then I also wonder if the people who apply the logic and program the logic into the elevators are actually evil sadists that are doing it on purpose to make us wait longe…

> minimize the amount of wait times between picking up people and taking them to their destination I wish elevators accounted for load. I've been to a couple of larger conferences where on the Monday morning after, the hotel elevator was just hammered. Everyone wanted to go down, and the elevator would dutifully stop on every single floor no matter how full it was. If you were mobility disabled on the 2nd floor, you…

> If you were mobility disabled

In one of the buildings where I worked, "fancy Destination Dispatch kiosk" had a separate button with a wheelchair pictogram that would ensure that the elevator has enough space for a wheelchair.

I'd like to see skyscraper elevators simulated, not just a few floors.

They have to be built a certain way, and need super fancy dispatch algorithms.

For folks that have never seen elevator scheduling the game: https://play.elevatorsaga.com/ Enjoy this rabbit hole :D

I wish there were more games like this. It’s such a simple premise but so satisfyingly difficult after each level. And it even has a bit of randomish failure which makes for even more challenge.

I had the idea to build something like it but for traffic lights. Never got around to actually do it. I have a feeling it probably exists.

My wife always randomly hits the up or down button, then gets upset if I explain why she should only pick the one she really wants. She forgets the next time. I think some people never really understand how elevators work. See also: the keep open / close doors button. I had one building administrator explain to me we should add a delay of 10 seconds to the "quickly shut door" button because otherwise she kept getting…

I fear in both cases, its not a lack of understanding of elevators but of common sense...

For these people, replace the buttons entirely with a voice-activated destination request on proximity.

This is great, but to me, the definitive elevator scheduling game was SimTower.

Sid Meier's Elevator Manager was such a great game... so much nostalgia.

Yoot Saito, actually, although it does really feel like a Sid Meier or a Will Wright game.

That's the guy who created Infiniminer, which was essentially 3D multiplayer Motherlode (a game everyone was playing at school lunch and I never figured out why) and inspired Minecraft.
