Abstract: Devices, methods and computer programs for elevator call allocation with stochastic multi-objective optimization are disclosed. At least some of the disclosed embodiments allow an elevator group control to take into account knowledge about possible future passenger arrivals when allocating new calls. At the same time, the new elevator calls can be allocated via optimizing multiple objectives, such as the waiting time, the time to destination, and/or the energy consumption. In other words, the invention makes it possible to both take into account the uncertainty related to future passengers and control the trade-off between different optimization objectives.
