Actually, yes...they do. I work in a building with an elevator control system designed by an internal engineer.
More importantly, the elevator control system uses mathematical expertise that is normally used solving variants of the multi-commodity flow problem, used extensively in the Supply Chain.

- reledi 14y agoHeh, that's pretty cool. How does it compare to the average elevator?
- sib 14y agoWhen load is not particularly high, it works well (seemingly efficient for passengers and in energy consumption). When load gets high (think ~noon), it tends to perform pretty badly in terms of latency.
- saosebastiao 14y agoSib has it about right. It is an NP complete problem, and I'm pretty sure the solution is using a Heuristic, but it does seem to be pretty suboptimal during lunch time. Then again, maybe it just seems worse because you wait longer as a tradeoff to having a faster ride to your floor.
