In a method for allocating an elevator in an elevator system, the elevator system including elevator groups, each group including elevators, the elevator groups being formed based on a load unbalance of the elevators, the method includes: detecting received service calls in a predefined time window; evaluating a number of passengers requesting service based on the received number of service calls; selecting, based on the evaluated number of passengers, an elevator group to serve the floor; and allocating an elevator belonging to the selected elevator group to provide service. An apparatus, an elevator system, and a computer program are also disclosed.

According to an embodiment there is provided a building automation system control apparatus comprising building automation system control logic configured to receive signaling from entities connected to a building automation system and to cause transmission of control signaling to the entities connected to the building automation system, wherein the building automation system control logic comprises elevator control logic as an integral part to directly control an elevator system comprising one or more elevators, the building automation system control logic being configured to take into account signaling received from the entities connected to the building automation system when determining control signaling for the elevator system; and the building automation system control logic being configured to take into account signaling received from the elevator system when determining control signaling for the entities connected to the building automation system.

A method of controlling an elevator system incudes collecting one or more frustration indicators of a passenger during usage of the elevator system by the passenger; collecting one or more frustration factors; correlating the one or more frustration factors to the one or more frustration indicators to generate one or more preferences for the passenger; generating a profile for the passenger in response to the correlating, the profile including the one or more preferences; and controlling operation of the elevator system in response to the one or more preferences to reduce frustration of the passenger during interaction with the elevator system.

A group control device according to the present disclosure includes a registration unit, a calculation unit, and a selection unit. The registration unit makes call registration for a boarding floor, a destination floor, and an allocated car when a user makes a hall destination call by a hall destination calling device. The calculation unit calculates an in-car stay time of the user for the hall destination call. The selection unit selects a past hall destination call as an alternative candidate for call registration for a new hall destination call, in a case where the past hall destination call which has already been registered by the registration unit, whose allocated car is different from a car allocated to the new hall destination call, and whose in-car stay time is shorter than the in-car stay time calculated by the calculation unit.

An elevator operation managing device capable of reducing a switching of passengers at a time of getting on and getting out of a car. The elevator operation managing device includes an in-car position acquisition unit and a car allocation acquisition unit. The in-car position acquisition unit obtains an in-car position of a user based on layout information and a congestion degree obtained in a congestion degree acquisition unit. The car allocation acquisition unit performs a car allocation to allocate the user to the car based on a received boarding floor and destination floor and the in-car position obtained in the in-car position acquisition unit.

Provided is an elevator system capable of improving the operation efficiency of an elevator. An elevator system according to the present invention includes: first processing circuitry to receive destination floor information transmitted from a movable body having a movement mechanism and second processing circuitry and being capable of boarding and alighting from a car of an elevator, to assign the car, in which a plurality of onboard positions are set, to a call based on the destination floor information received, and to assign one of the plurality of onboard positions to one movable body based on a destination floor of the movable body. The first processing circuitry transmits to the movable body information indicative of the onboard position assigned to the movable body.

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 control apparatus for shortening the sum of the waiting times of waiting people waiting for elevators on all floors includes an analysis unit configured to analyze each of images obtained by capturing elevator boarding/exiting portions on floors where an elevator car can stop, and to recognize a person in the image, an acquisition unit configured to, based on a result of the analysis by the analysis unit, acquire an elevator usage history of the person, and a generation unit configured to, based on the elevator usage history acquired by the acquisition unit, generate an operation schedule for the elevators.

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.

An elevator installation for serving at least one floor in at least one building can be modernized, the elevator installation comprising at least one elevator with at least one elevator car and at least one elevator control. At least one destination call terminal for input of at least one destination call and/or for recognition of at least one identification code is installed on at least one input floor. At least one destination call control is installed. The destination call terminal is, for communication of the destination call signal, connected with the destination call control. The destination call control can be connected to the elevator control through a serial interface of the elevator control.
