Devices, methods and computer programs for elevator call allocation with stochastic multi-objective optimization are disclosed. At least some of the disclosed embodiments allow an elevator group control to take into account knowledge about possible future passenger arrivals when allocating new calls. At the same time, the new elevator calls can be allocated via optimizing multiple objectives, such as the waiting time, the time to destination, and/or the energy consumption. In other words, the invention makes it possible to both take into account the uncertainty related to future passengers and control the trade-off between different optimization objectives.

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 control method is implemented by a computer and comprises: receiving a board request from a board-standby robot; determining a priority of the board-standby robot based on information relating to the board-standby robot and operation information of the elevator; and controlling operation of an elevator car based on the priority of board-standby robots and the priority of on-board robots within the elevator car.

In an elevator installation, an elevator control system is configured to receive an elevator call from a person via a call terminal and from a robot via a radio transceiver. A current transport capacity of the elevator installation is determined. An elevator call originating from the robot is recognized by the elevator control system, the call including a priority level set by a dispatcher, wherein the priority level is one of a high, a medium and a low priority range, wherein the elevator call is indicative of a boarding floor. The allocation of the elevator call originating from the robot to the elevator car is delayed if the priority level is set to the medium priority range and the current transport capacity is lower than a first threshold value, or if the priority level is set to the low priority range and the current transport capacity is lower than a second threshold value.

An elevator system is provided. Aspects includes an elevator car, a sensor affixed to the elevator car, wherein the sensor is operated by a controller, the controller is configured to receive occupancy data associated with the elevator car. The occupancy data is analyzed to determine an occupancy of the elevator car. A first hall call is received and based at least in part on the occupancy and the first hall call, adjusting operation of the elevator car in the elevator system.

A system includes an elevator system including an elevator car. The system also includes a control system configured to receive a crowd reduction indicator, determine an elevator car load reduction for the elevator car based on the crowd reduction indicator, adjust an elevator car load limit based on the elevator car load reduction, and trigger a mitigation action in the elevator system based on detecting a condition that exceeds the elevator car load limit.

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.

According to an aspect, a method includes receiving a passenger request to reserve an elevator car of an elevator system to travel to a targeted destination. At least two different travel options to the targeted destination are determined based on a plurality of elevator car travel plans comprising at least two elevator cars having different travel ranges. The at least two different travel options are output to an interactive display. At least one of the at least two elevator cars is reserved responsive to a user selection of one of the at least two different travel options.

In the present invention, a process of receiving an image obtained by capturing a measurement target place with a camera, calculating a number of people in the measurement target place based on the image received, and allocating a car according to the calculated number of people is performed. Here, when an abnormality that an image from the camera cannot be received is determined, a process of referring to a detection value of a sensor or the like installed in a car or in the measurement target place to calculate the number of people in the car or the measurement target place is performed.

An illustrative example embodiment of a method of managing risk associated with at least one individual moving within a building includes: determining a beginning location and a destination of an individual, wherein the beginning location and the destination are on different levels of the building; determining a risk contribution of the individual based on an indication of at least one characteristic of the individual; determining a plurality of routes between the beginning location and the destination; determining a risk factor of each of the plurality of routes based on the risk contribution of the individual and other risk information regarding the respective routes; and determining a recommended route from among the plurality of routes for the individual to arrive at the destination, wherein the risk factor of the recommended route is lower than the risk factor of at least one other one of the plurality of routes.
