Abstract: Embodiments herein relate to an elevator system of a facility with multiple floors. The elevator system can comprise elevator cars and an elevator controller. The elevator controller includes a memory and a processor. The memory stores computer program instructions executable by the processor to cause the elevator system to determine a current utilization of the elevator system, automatically activate an adaptive split group operation on a per floor basis when the current utilization of the elevator system is greater than a threshold utilization of the elevator system, and dispatch the elevator cars under the adaptive split group operation in accordance with elevator calls.
