Abstract: A genetic allocation method in an elevator group for allocating a landing call to one of several elevator cars in the elevator group, the cars moving and stopping within the area of several different floors. The elevator travel routes are encoded into alternative chromosomes. Using genetic methods, alternative chromosomes are developed and the best chromosome is selected. The elevator group is controlled in accordance with the best chromosome. The floors served by the elevator group are divided into a first group and a second group. On the floors of the first group, landing calls are given as passenger-specific destination calls. On the floors of the second group, landing calls are given as floor-specific up/down calls. When the destination calls and up/down calls are encoded into the same chromosome, the best chromosome represents an allocation decision, in which the gene values indicate which elevator car is to serve each passenger and each up/down call.

Abstract: An elevator group control method for the allocation of calls, in which method a given service time of the elevator group is assigned a target value. The service time may be passenger waiting time, call time, traveling time, riding time or an average value of one of these quantities. The method aims at fulfilling the assigned target value in such a way that the energy consumption of the elevator system is minimized. Optimization is implemented using a model of the elevator system, by means of which the desired service time can be predicted. This prediction is utilized in a controller controlling the optimizer. This makes it possible to improve the construction and operation of the controller and optimizer so that the energy consumption of the elevator system can be reduced while the condition regarding the target service time is fulfilled at the same time.

Abstract: A method for allocating calls entered via the landing call devices of elevators belonging to an elevator group so that there are simultaneously at least one floor to be signaled according to the service routes of the elevators. The allocation decision is is made by a genetic allocation method. The allocation decision is input into a call fixation control unit, which takes care of the reservation and release of landing calls and the control of signaling. In the case of a reserved landing call, the range of values of the gene is limited.

Each allocating option contains, for each active landing call, a call data item and an elevator data item which together are used to determine which elevator should service the call. The value of a cost function is calculated for each allocation option; one or more of the allocation options is repeatedly changed with respect to at least one data item, and the values of the cost functions of the new allocation options are calculated. Based on the values of the cost functions, the best allocation option is selected and the active elevator calls are allocated to the elevators in the elevator bank accordingly.

Abstract: A method and apparatus for controlling doors of an elevator includes a passenger sensor and load sensor. The passenger sensor detects the presence of passengers in a lobby, and the load sensor generates a load signal indicating only a load of the elevator. A processor then determines passenger movements between the lobby and the elevator, and passenger movements within the elevator based on the load signal. Next, an elevator door controller controls the elevator doors based on output from the processor and the passenger sensor.
