Some people are bound to ask "What's with all this obsession with elevator control circuits anyway?"
Elevator control is one of the classic (and oldest) problems of servo and feedback systems...and actually skirts on the topic of artificial intelligence.
They first started thinking analyitically about this when building the Empire State Building....and the IDEAL solution still is not at hand.
There are a lot of aspects of this problem. WHO gets first dibs? First come first served may SEEM simple enough. However, it can be REALLY inefficient in energy, wear and tear, etc. Is it always most efficient to make a "milk run"...the elevator always moving in the same direction as far as possible?
It's one thing if all the INPUTS are addressed before the "route." But how about AFTER the "route" is started? What is the most equitable method to allow "interrupts?"
There's a lot more to this than meets the eye...which is why elevator problems will not go away soon...if ever.
