Procedure for controlling an elevator group where virtual passenger traffic is generated
First Claim
1. A method of controlling an elevator group including two or more elevators driven by hoisting machines and collectively controlled by a group control that adaptively assigns elevators to calls comprising:
- a) receiving a new landing call;
b) simulating probable future landing calls responsive to activating the new landing call;
c) allocating the probable future landing calls to the elevator group on the basis of the simulation of step b); and
d) reallocating the elevator group to one or more old calls based on the simulation if a time period for reserving the one or more old calls has not been exceeded.

Abstract
As elevator group including at least two elevator cars is controlled using a group control unit which allocates the calls to different elevators. Based on statistical data and/or statistical forecasts, virtual passenger traffic is generated and used in a simulation that creates events in the virtual passenger traffic, on the basis of which an elevator-specific cost is computed for each call to be allocated. Based on the costs, the best elevator is selected to serve the call. This allocation of a best elevator to answer a specific landing call may be reallocated as the simulation is updated to update the best elevator to answer a specific floor call.
