Patent ID: 7694781

Claim:
A method for allocating destination calls in an elevator system, said elevator system including at least one multi-deck elevator, and a destination call device with which a passenger gives his/her destination floor at the beginning of the journey route, thereby defining the starting point and final point of the passenger's journey route in the elevator system, the method comprising: generating possible route alternatives from the starting point to the final point of the passenger's journey route; determining a cost function for the route alternatives, said cost function containing at least one travel time term; determining the value of the at least one travel time term corresponding to each route alternative in the cost function; calculating the total cost of each route alternative by using the cost function; allocating, for the passenger, the route alternative having the lowest calculated total cost; guiding the passenger to a waiting lobby and/or elevator according to the route alternative allocated; and generating a transfer route model in which one or more travel time forecasts for one or more transfer routes in the elevator system are determined on the basis of a criterion dependent on a state of the elevator system.
