Schedulers for Multi must be fun - I'm sure they must have employed a whole research group for solving this problem. Scheduling simple elavator systems is still a problem nowadays, this one? It's so much harder.

Nothing a little deep learning can't solve. Right? Right guys?

Sounds like it'd be a fun game

    Thank you for sharing this. I've also now lost quite a few hours to it. Also got two of my coworkers into it.

I'm rather sure they haven't. Source: Myself, working in a high-rise building served by ~20 ThyssenKrupp elevators, 10 of which actually share 5 shafts (they're not the ropeless version though, AFAIK), and the scheduling sucks big time. We got them to informally acknowledge that they're being wiped every night to get around some nasty bugs, so they never learn traffic patterns, but even then it's infuriating to see how crap they are even on a Sunday with the building empty.

  I've seen them work ok in an office building with ~15 floors and 6 elevators until lunch time, when the extra traffic made them take far longer than it seemed they should have. I'm guessing those didn't detect if no one got in the car and they still went to all their scheduled floors.

    I'm sure it's more than that: The express lifts remain for too long at the "key" floors to pick up more people. This is probably some energy vs practicality balance that can be adjusted, and that we're very likely guilty of. The normal lifts will happily depart with nobody inside if you don't sprint to them because the consoles are 25ft away. You book 2 adjacent floors, you get 2 lifts scheduled for only those floors. So much for saving energy, and also, now 2 lifts are busy instead of 1. The fancy giant touchscreens are a nightmare: small touch targets, 80% of the screen devoted to static diagrams, the resistive touch film already failed in the hot spots, esp. because you are forced to touch some areas even though you have no choice!! (Choose north or south tower. Oh you chose the south tower but you're in the north one. Sorry you can't do that). I could go on... but, in a nutshell: these people can do hardware. They fail big time at software, both the scheduling engine and the UI.
