An exercise necessity degree determination unit (13) determines an exercise necessity degree being a degree to which an elevator user needs to exercise, who uses an elevator (50) provided in a building provided with an inter-floor travel means other than the elevator. A floor decision unit (14) changes based on the exercise necessity degree of the elevator user determined by the exercise necessity degree determination unit (13), at least one of a boarding floor and an alighting floor of the elevator (50) from a floor that the elevator user prefers to another floor so as to let the elevator user use the inter-floor travel means before the elevator user reaches a destination floor to which the elevator user intends to go.

Provided are embodiments for a system and a method for performing passenger grouping in an elevator system. Embodiments includes receiving a call request placed by a user, and receiving user condition data for a user obtained using one or more sensors operably coupled to the controller. Embodiments also include calculating a final exposure rating based at least in part on the user condition data, and assigning the user to an elevator based at least in part on the final exposure rating.

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.

The invention improves control of wear and tear of the elevators in an elevator group having a plurality of elevators and at least one group control unit. The actual usage of each elevator is recorded, and the group control unit executes at least one allocation algorithm for selecting which elevator of the elevator group is used to serve a call. The allocation algorithm compares the actual usage of at least two elevators against respective target usages and selects the elevator having its actual usage most deviating from the target usage to serve an outstanding call. With the invention, the wear and tear of elevators may be balanced, or certain elevators may be set to reach the end of the maintenance period sooner.

An elevator system is configured to be capable of accepting an internal call made by a user operating an elevator operating panel and an external call made from an external apparatus using a communication network. The elevator system is provided with a processor that assigns a car to be an arranged-car candidate to an internal call or an external call from among one or more cars. The processor is configured to, when an external call is accepted, execute an operation condition judgment process for judging whether each of the one or more cars is in an operating state or in a non-operating state and an external call assignment process for preferentially assigning a car in the non-operating state as the arranged-car candidate over a car in the operating state.

Apparatuses, methods and computer programs for elevator call allocation with adaptive multi-objective optimization are disclosed. At least some of the disclosed embodiments may allow adaptively and smoothly changing an objective function according to passenger traffic. This in turn may allow minimizing waiting times in all traffic situations compared to using a fixed objective function. Furthermore, at least some of the disclosed embodiments may allow adaptively and smoothly changing the objective function according to the traffic while taking user preferences into consideration via a single transit time target parameter.

An elevator system in a building having a plurality of levels, the system having elevator cars, a controller operationally coupled to the elevator cars, and configured to receive a service request, and render a first determination to select one of the elevator cars to respond to the service request, wherein the controller is configured to render the first determination from a determination of one or more of an elevator health and usage state of the elevator cars, and a travel time to respond to the service request by each of the elevator cars.
