A method of operating a dispatcher of an elevator group of a building elevator system having a plurality of elevator systems organized into multiple elevator groups including: receiving an elevator call, the elevator call including a desired destination; transmitting elevator status data from the elevator group to one or more other elevator groups of the building elevator system; receiving elevator status data from each of the one or more other elevator groups of the building elevator system; determining a verdict depicting whether an elevator car of the elevator group is best to serve the elevator call in response to the elevator status data of each of the one or more other elevator groups of the building elevator system; and calling an elevator car in response to the verdict.

A method of operating a building elevator system within a building having a plurality of floors is provided. The method including: controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further include a first elevator car; controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further include a second elevator car; monitoring usage of the first elevator group and second elevator group; and reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to usage of the first elevator group and usage of the second elevator group.

A method of operating a building elevator system within a building having a plurality of floors including: controlling a building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car; determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simultaneous up peak or inter-floor traffic, the one or more sectors comprising a first sector having a first plurality of floors and a second sector having a second plurality of floors; assigning the first elevator car to the first sector; and assigning the second elevator car to the second sector.

An elevator system includes at least one elevator group control with a destination control system, at least one elevator group having elevators with a different destination range, destination operating panels at each landing including an input for issuing destination calls, car operating panels located in the elevators having an input for the input of destination calls, hall lanterns for each elevator indicating the moving direction of the corresponding elevator, a signaling device for each elevator indicating the arrival of an elevator at the landing, the destination control system controls hall lanterns to indicate a moving direction of the elevators and activates the signaling device when elevators arrive at a landing. The destination control system displays, after the issue of a destination call, a range identifier indicative of the elevator's destination range, and the next arriving elevator by activation of its signaling device before its arrival at the landing.

A ropeless elevator system may include a plurality of elevator cars, a first hoistway, a second hoistway, an upper transfer station, and a lower transfer station. Movement of each of the plurality of elevator cars may be controlled according to a predetermined assignment in which: a plurality of floors is divided into a plurality of floor groups, each of the plurality of elevator cars is assigned to at least one of the plurality of floor groups, and each of the plurality of elevator cars is dispatched only to floors within the at least one floor group assigned thereto.

An illustrative example embodiment of an elevator system includes: a plurality of elevator cars; a plurality of elevator machines, respectively associated with the elevator cars to selectively cause movement of the associated elevator car, at least some of the elevator machines respectively operating in a first mode including consuming power and in a second mode including generating power; a power source having a power output threshold and a power intake threshold; and at least one controller that is configured to determine when the power source is providing power for the elevator system, and dynamically adjust how the plurality of machines move the elevator cars to maximize a number of the plurality cars being used to move passengers while keeping power consumption by the elevator system below the power output threshold and keeping power generation by the elevator system below the power intake threshold.

A method of operating a building elevator system within a building having a plurality of floors is provided. The method including: controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further include a first elevator car; controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further include a second elevator car; monitoring usage of the first elevator group and second elevator group; and reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to usage of the first elevator group and usage of the second elevator group.

An elevator controller that enables enhancement in serviceability, avoids a collision between multiple cars that ascend/descend inside a common shaft, and suppresses increase in the number of floors a car cannot reach. The elevator controller includes: multiple cars arranged inside a common shaft such that each car can ascend/descend independently; an occupied area setting mechanism setting, for each of the multiple cars, a maximum area of a travel section necessary for the car to make an emergency stop as an occupied area for the car based on a running speed, a running direction, and a call registration status; and a running speed setting mechanism setting a running speed of a car so a number of floors the car can service is maximized within a range in which the car can make an emergency stop without entering an occupied area set by the occupied area setting mechanism for the other car.

Lift systems may include a first shaft unit and a second shaft unit, each of which may include a number of lift shafts. One or more single-car systems and/or multi-car systems may be disposed in the first shaft unit, whereas one or more shaft-changing multi-car systems may be disposed in the second shaft unit. A transporting operation may be carried out from an initial floor to a destination floor wherein a control unit determines whether to utilize one or more cars from the single car systems, the multi-car systems, the shaft-changing multi-car systems, or some combination thereof depending on factors such as the destination floors of the passengers, traffic density, energy demand, and/or availability of cars.
