Abstract:
A system 110 includes an input/output 113 unit for receiving a user request to call an elevator 101, 102 and a processor 111 for processing the user request to assign an elevator to the user 105. The processor performs one of a first assignment process and a second assignment process. The first assignment process includes determining whether a delay condition exists for delaying assignment of the elevator to the user 202, delaying assignment of the elevator to the user based on determining that the delay condition exists 203, and assigning the elevator to the user based on determining that the delay condition does not exist 204. The second assignment process includes assigning the elevator to the user and notifying the user of the assignment, determining whether an assignment change condition exists 206, changing the assignment to another elevator based on determining that the assignment change condition exists 207, and notifying the user of the assignment change 208.
Abstract:
The invention concerns a method for a passenger-allocation in a multi-deck elevator group, the decks of which defining elevator cars, respectively, being stacked above each other and being mounted in a car frame to be moved synchronously in an elevator shaft. 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 can create a number of allocation proposals calculated by means of an optimization algorithm carried out by the control unit for dispatching an elevator to a passenger call. The invention is characterized in that said 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 either for any further incoming call independent of whether said further incoming call is creating new elevator allocation proposal(s) or when a reallocation timeout has passed. The invention further relates to a computer program carrying out the inventive method.
Abstract:
The present invention provides a method and apparatus for use in elevator systems for assigning new hall calls to one of a plurality of available elevator cars. The method comprises calculating for each car a call cost for accepting the new hall call. The call cost is a function of the estimated time to the desired destination of the passenger requesting the new hall call and of the delay that other passagers who are using the elevator car will experience. In one embodiment, a destination is inferred for the passenger requesting the new hall call. In another embodiment, the passenger requesting the hall call may input a desired destination at the time the hall call request is made. The elevator system of the present invention allows for use of both standard up/down hall call entry devices and destination entry devices that allow a particular destination to be entered by a passenger at the time a hall call is requested.
Abstract:
An elevator group comprising at least two elevator cars (Car1, Car2) is controlled using a group control unit which allocates the calls to different elevators. Based on statistical data and/or statistical forecasts, a virtual passenger traffic is generated and simulation is applied to create events in the virtual passenger traffic, on the basis of which an elevator-specific cost is computed for each call to be allocated. Based on the costs, the best elevator is selected to serve the call.

Abstract:
To assign a car to a hall call such that cars A, B, C, D tend to be equally spaced apart and so that bunching of cars is avoided, the position of each car is predicted over a given period by estimating where it will arrive and leave each of its committed stops over that period for a given set of hall call/car call assignments, a bunching measure is calculated and a car to hall call assignment is made in response to the bunching measure.
Abstract:
An elevator control system employing a micro-processor-based group controller ( Fig. 2 ) which communicates with the cars of the elevator system to determine conditions of the cars and responds to hall calls registered at a plurality of landings in the building serviced by the cars under control of the group controller, to provide assignments of the hall calls to the cars based on a weighted summation for each car, wi h reapect to each call, of a plurality of system response factors, some indicative, and some not, of conditions of the car irrespective of the call to be assigned, assigning "bonuses" and "penalties" to them in the weighted summation. In the invention, rather than a set of unvarying bonuses and penalties being assigned based on the relative system response factors, the assigned bonuses and penalties are varied (4,6) based on the perceived intensity of traffic, as measured (3,5) by, for example, a past average waiting time and the elapsed time since registration of the hall call, a selected past five minute average waiting time being exemplary.
Abstract:
PROBLEM TO BE SOLVED: To provide an elevator group management device that improves operation efficiency in consideration of a change of state generated after a destination floor is registered at an elevator hall.SOLUTION: An allocated car review means 21 executes allocated car review processing for each allocation registration information set comprising at least one piece of temporary allocated car registration information managed by a registered destination floor hall call management part 13, in a review period. The allocated car review means 21 modifies the temporary allocated car registration information in the registered destination floor hall call management part 13, on the basis of the content of the modified allocation registration information set when the allocated car review processing ends. Consequently, the allocated car review means 21 registers new temporary allocated car registration information, and deletes the previous temporary allocated car registration information, as well.
