A method for a passenger-allocation in a multi-deck elevator group where the decks of the elevator cars are stacked above each other and being mounted in a car frame to be moved synchronously in an elevator shaft utilizes an improved allocation strategy. The method is performed by a control unit to dispatch the elevator cars for serving any passenger call which can be entered as a landing call or a car call, wherein a call creates plural allocation proposals calculated by an optimization algorithm carried out by the control unit for dispatching an elevator to a passenger call. The allocation proposals are then processed in a routing algorithm defining one serving deck to be taken for the allocation of a specific call, which routing algorithm is restarted for any further incoming call independent of whether a further incoming call is creating new elevator allocation proposal(s) or when a reallocation timeout has passed. A computer program carrying out the method is further disclosed.

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.

An elevator that incorporates a framework that allows multiple autonomous mobile lifts to move independently inside and outside a building or a group of buildings in shafts and corridors in such a way that multiple lifts can share a shaft and/or corridor.

Systems and Methods for controlling a movement of cars of an elevator system. A processor determines for each car an individual waiting time of each hall call. Determines for each pair of hall calls assigned for each car, a pairwise delay over the individual waiting time of each hall call in the pair caused by a joint assignment of the car to the pair of the hall calls. Approximate a cumulative waiting time of an assignment of the cars to the hall calls as a sum of individual waiting times for each hall call with the assigned car and a sum of all pairwise delays determined between all pairs of hall calls assigned to the same car. Determine the assignment of the cars using a greedy optimization algorithm that greedily assigns hall calls to the cars to minimize the approximated cumulative waiting time, and control the movement of the cars.

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.

The invention refers to an elevator system having a plurality of elevator cars, which elevator cars comprise several first cars and at least one second car, which second car differs from the first cars in its size and/or technical configuration, whereby the first cars and the second car run together within one and the same elevator shaft, which elevator system comprises an elevator control comprising a call allocation control having a first part connected to at least one call input device for allocating the first elevator cars and a second part connected to at least one call issuing means for the call allocation of the second car, whereby the first and second part of the call allocation control are configured to work independently of each other.

A method of operating an elevator system includes: receiving an evacuation call from a first evacuation floor; moving a first compartment of a multi-compartment elevator car to the first evacuation floor; opening a first door of the first compartment when the first compartment arrives at the first evacuation floor; monitoring, using a first sensor system, a remaining capacity within the first compartment; and closing the first door when at least one of a first selected period of time has passed and the remaining capacity within the first compartment is equal to a first selected remaining capacity.

An elevator control of a one-shaft multicar system includes: a collision predictor predicting occurrence of a collision of cars against each other in a same shaft in a case a predetermined collision prediction implementation condition is held; a waiting-with-door-open determination mechanism determining whether or not a car is caused to be on standby with the door thereof kept open in a case the collision predictor predicts the collision of cars against each other in the same shaft; a waiting-with-door-open floor determination mechanism determining a waiting-with-door-open floor of the car in a case the waiting-with-door-open determination mechanism determines the car is caused to be on standby with the door thereof kept open; and a controller causing at least either of the cars, for which occurrence of a collision is predicted, to be on standby with the door thereof kept open at the waiting-with-door-open floor determined by the waiting-with-door-open floor determination mechanism.
