Every time I use the lifts in the building I work in I think of this question. There's only 7 floors, yet the software appears to be rubbish. The idle time question is an interesting/important one, arguably the more important for elevators for relatively low utilisation, where the capacity is there, but you wait for a lift as they are all elsewhere. In my building it seems that not only do the elevators not have sensible 'resting points' at peak times of the day, it seems that it also doesn't weight requests at all, so you get a massive number of people waiting at the ground floor, as only one lift is sent at a time. And even if there are multiple elevators waiting at the ground floor, they will only open one at a time, once another lift has left.
