A method including monitoring a plurality of elevators, wherein at least two of the plurality of elevators are set into a shuttle mode in which the corresponding elevator travels between two pre-defined floors; calculating at least one of an arrival time and a departure time of an elevator car of each of the at least two elevators in the shuttle mode at a predetermined floor; determining a time required by a user for reaching each of the at least two elevators in the shuttle mode from an operation terminal location; calculating a preference order of the at least two elevators in the shuttle mode on the basis of the time of arrival and/or departure of the elevator car of each of the at least two elevators in the shuttle mode and the time required by the user for reaching each of the at least two elevators in the shuttle mode from the operation terminal location; assigning one of a plurality of display modes to each of the at least two elevators in the shuttle mode according to the preference order; and causing displaying of an elevator identification according to the preference order by using the assigned display mode.

A method monitors a plurality of elevators, in which at least two elevators are set into shuttle mode in which the corresponding elevator travels between two pre-defined floors. The method calculates at least one of an arrival time and a departure time of an elevator car of each of the at least two elevators in shuttle mode at a predetermined floor; determines a time required by a user for reaching each of the at least two elevators in shuttle mode from an operation terminal location; and calculates a preference order of the at least two elevators in shuttle mode on the basis of the time of arrival and/or departure of the elevator car of each of the at least two elevators in shuttle mode and the time required by the user for reaching each of the at least two elevators in the shuttle mode from the operation terminal location.

The present disclosure relates to a method for operating an elevator system, which is embodied as shaft-changing multi-car system. A number of cars is assigned to at least three elevator shafts. The cars can be moved in upwards direction and downwards direction inside the individual elevator shafts, as well as between the individual elevator shafts. A successive reversal of the travel directions of the respective cars occurs hereby.

A system for allocating elevator use based on an individual request includes a request module that receives a reservation request of an elevator car from a user, an allocation module that identifies a reserved elevator car based on the reservation request; and a mechanical control module that moves the reserved elevator car in response to commands provided by the user and the reservation request.

An elevator system, including at least one first guide rail, which is oriented in a first, in particular vertical, direction, at least one second guide rail, which is oriented in a second, in particular horizontal, direction, a plurality of rotatable rail segments, wherein at least one thereof is transferable between an orientation in the first direction and an orientation in the second direction, at least one elevator cab, which is transportable along the guide rails and which, via the rotatable rail segments, is transferable between the different guide rails, at least one third guide rail, which is oriented in a third, in particular horizontal, direction, and wherein at least one of the rotatable rail segments is transferable between an orientation in the first or second direction into an orientation in the third direction.

According to an aspect, there is provided a method for managing elevator cars in a multi-car elevator shaft system. The method comprises determining, by an elevator control entity, the optimum number of elevator cars for a given time of a day in the multi-car elevator shaft system; and commanding, by the elevator control entity, at least one elevator car into at least one elevator car storage or back to service from the at least one elevator car storage based on the determination, wherein elevator cars in the at least one elevator car storage act as standby elevator cars for the multi-car elevator shaft system.

According to an aspect, there is provided a method for determining the number of elevator cars in a two-shaft multi-car elevator system. The method comprises determining the number of active elevator cars N in the two-shaft multi-car elevator system by

[00001]$N=\frac{\mathrm{RTT}*\mathrm{arr}}{a*\mathrm{carsize}},$

wherein RTT is a round trip time of the two-shaft multi-car elevator system, arr is the arrival rate of passengers, a is a car load factor, and carsize is the number of passengers one elevator car is able to carry.

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.

A method of assigning destination call in an elevator group forms chromosomes including genes where each gene is a correlation of a call and an elevator trip, the possible round trips are calculated, each round trip is evaluated for optimization procedure. The calls are assigned to the elevators by the destination call control based on the best chromosome determined.

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.
