Yeah, intuitively the request floor instead of up-down paradigm always seemed inefficient. However, if the issue is that it forces a single elevator and doesn't allow reoptimisation, I wonder if there's a middle ground where instead of up down there's a button panel for the floors, but you still just take whatever elevator's going up? It technically wouldn't require double work but kind of feels like it does psychologically - anyone seen prior work on this?

#212Simulating Elevators in TLA+ is a fun exercise.

Another interesting, and underrated one: hotel keys.

#213“The elevator did hear you, it just has a lot to think about”
Didn’t anticipate that my day would be bookended by relating to and empathizing with the plight of the elevators while I wait for one in a tall corporate building.
Pressed the kiosk some time ago but watching the sun begin to arc towards setting it does appear the world can change a lot in 30 seconds.

I don't know, what about jerks pressing every button because they want to make you wait? The downside risk here strikes me as much more unlikely than the upside.
Jerks do push all the buttons to make everyone else wait. It's why newer elevator systems are often configured to ignore those if too many floor buttons get pressed at once.
> Jerks do push all the buttons to make everyone else wait.
That's my point. The attack goes away if you can un-press buttons.

If you liked SimTower, Project Highrise is worth taking a look into. https://store.steampowered.com/app/423580/Project_Highrise/
Project Highrise doesn't have elevator simulation. Elevator is just portal that teleports the sim to proper floor.
Yeah, the fact that Project Highrise doesn't handle the transportation part of the game means that it never scratched the same itch SimTower did.

Not to mention maintenance means taking an elevator out of service, meaning average wait times go up during that period.
Someone needs to design an elevator that only breaks down between midnight and 5am. Maybe a different model to accommodate late night crowds returning to large residential buildings.
I mean, "breaks down" is different from "scheduled maintenance". Most definitely the later can be scheduled during less busy hours.

Yeah, maybe that's what was it.
Tbh, while I bring up Project Highrise whenever someone mentions SimTower, I did always feel like it was missing something. Something always felt slightly soulless about Project Highrise.

For me the issue is that it doesn’t look and sound like Sim Tower. Which I’m sure is mainly just nostalgia but that’s still a valid reason why I probably love it so.

Is it because the criteria is wait time not travel time? Destination dispatch would avoid some extra stops on the trip. I just visited a new building with destination dispatch, so it seems to be still around. My EE roommate in college had to build an elevator circuit as a final problem. It was on a bread board and had a bunch of call buttons and had a motor and a clear disk with black squares so it could figure out w…
> Is it because the criteria is wait time not travel time? Yeah, it doesn't make any sense to optimize wait time instead of total time from pressing the button to reaching destination.
It very well could be the case that people get more upset about waiting for the car than total travel time when they are already in the car. Ie, pick them up sooner even if travel time is longer. In fact, I would bet that this is the case.
