An elevator control method is implemented by a computer and comprises: receiving a board request from a board-standby robot; determining a priority of the board-standby robot based on information relating to the board-standby robot and operation information of the elevator; and controlling operation of an elevator car based on the priority of board-standby robots and the priority of on-board robots within the elevator car.

A method for controlling a passenger flow in a building includes: dividing a group of elevators to sub-groups; receiving a service call; selecting a sub-group to provide a service and generating an indication for indicating the selected sub-group; selecting a first candidate elevator; evaluating a second candidate elevator by comparing the second forecast time to the first forecast time; selecting the second candidate elevator to provide the service if the second forecast time is less than the first forecast time. The evaluation is continued until a selection is locked for the service call due to at least one characteristic relating to the elevator system. The invention also relates to a group controller, a computer program product, and an elevator system.

A method schedules elevator cars in a group elevator system in a building by first generating a set of probability distributions for arrivals of future passengers at any floor of the building, wherein the set of probability distributions are characterized by probabilistic variables that specify arrival information of the future passengers, wherein the arrival information includes a probability of service requests by the future passengers and a probability of possible times of the service requests. A schedule for the elevator cars is based on the set of probabilistic distribution. Then, the schedule is provided to a controller of the group elevator system to move the elevator cars according to the schedule.

A method includes recording a primary destination dispatch request from a primary passenger at a first floor position via a destination dispatch controller 115, identifying a terminal floor, providing a terminal floor call signal to the elevator control system via an overlay controller 110, moving an assigned elevator car in a travel direction of the terminal floor, recording at least one secondary destination dispatch request from a secondary passenger at a respective at least one secondary floor position via the destination dispatch controller, approximating a position of the assigned elevator car, determining a target floor position via the destination dispatch controller, entering a target floor call corresponding to the target floor position at a calculated time to stop the assigned elevator car at the target floor position, cancelling all pending calls via the elevator control system 102, and entering at least one recorded destination dispatch request to the elevator control system.

A method of operating a building elevator system having a plurality of elevator systems organized into multiple elevator groups including: receiving an elevator call from a destination entry device in communication with the building elevator system; obtaining a favorability score from each of the multiple elevator groups of the building elevator system; determining an elevator group of the multiple elevator groups with the highest favorability score; and routing the elevator call to the elevator group of the multiple elevator groups with the highest favorability score.

A method for reassigning a first elevator car of a plurality of elevator cars that includes dispatching the first elevator car from a current location to a first destination location to pick up an occupant at the first destination location. The method includes determining the first elevator car stopped at an intermediate location positioned between the current location and the first destination location. The method further includes determining a number of occupants within the first elevator car is greater than at least a second elevator car of a plurality of elevator cars after the first elevator car stopped at the intermediate location, and directing the first elevator car to a second destination location different from the first destination location.

One embodiment provides a method for optimizing schedules of a plurality of elevators in a building having a plurality of floors, including: receiving, from a user, an indication requesting that an elevator from the plurality of elevators stop at a particular floor, wherein each of the plurality of elevators has a schedule comprising floors where the elevator will stop; identifying the number of users in the elevator waiting area of each of the particular floors where an indication requesting a stop has been received; and updating, in view of the identified number of users at each of the particular floors, the schedule for the plurality of elevators to optimize the stops for the plurality of elevators, wherein the updating comprises dynamically routing the plurality of elevators upon (i) receipt of indications and (ii) identification of the number of users at each of the particular floors.

The invention relates to a method for allocating elevators of an elevator group to landing calls given in the elevator group, the elevator group having a control unit having a destination call control, which elevator control unit is connected to determining means for the prevailing traffic condition in the elevator group. Further the control unit comprises at least a first and second operating mode which are selected according to the prevailing traffic condition, wherein the first operating mode uses immediate call allocation of the elevators which includes the display of the allocated elevator on a destination operating panel immediately after having issued a landing call and wherein the second mode comprises the allocation of an elevator to a landing call before the arrival of the allocated elevator call to the landing where the landing call has been issued. The invention allows an adaption of destination control to different traffic situations.

A method of reassigning an elevator call for an elevator car comprising: receiving an elevator call from a mobile device, the elevator call including a destination request to travel from a boarding floor to a destination floor; assigning a first elevator car to the elevator call; activating an alert on the mobile device that the first elevator car has been assigned to the elevator call; determining that the first elevator car cannot serve the elevator call; assigning a second elevator car to the elevator call; and activating an alert on the mobile device indicating that the second elevator car has been assigned to the elevator call.

A method of reassigning an elevator call for an elevator car comprising: receiving an elevator call from a mobile device, the elevator call comprising a destination request to travel to a destination floor; assigning a first elevator car to the elevator call; determining that the first elevator car cannot serve the elevator call; activating an alert on the mobile device to enter any elevator car; detecting whether the mobile device enters a second elevator car; and assigning the second elevator car to the elevator call.
