Abstract
The invention improves control of wear and tear of the elevators in an elevator group having a plurality of elevators and at least one group control unit. The actual usage of each elevator is recorded, and the group control unit executes at least one allocation algorithm for selecting which elevator of the elevator group is used to serve a call. The allocation algorithm compares the actual usage of at least two elevators against respective target usages and selects the elevator having its actual usage most deviating from the target usage to serve an outstanding call. With the invention, the wear and tear of elevators may be balanced, or certain elevators may be set to reach the end of the maintenance period sooner.
