Abstract

During up-peak, a dispatcher selecting method chooses among three dispatching algorithms: (i) an up-peak sectoring scheme triggered when two cars leave the lobby fully loaded, (ii) static sectoring, and (iii) dynamic sectoring, in response to any of three criteria: car load, floor population, and average waiting time, allowing a group of elevators to be operated under any three of the dispatching algorithms, not locked into any two.
