Abstract:
A method of allocating calls of a lift installation with at least one lift and at least one car per lift to move passengers in a journey from at least one input floor to at least one destination floor, a system for executing the method and a computer readable memory with instructions for executing the method. The method includes receiving input calls from passengers travelling from an input floor to a destination floor, each call identifying at least one floor as an input floor or a destination floor. A start zone with identified input floors and a destination zone with identified destination floors are determined from the input calls and destination calls. Each identified floor within a corresponding zone is considered using at least one selection criterion and a stopping floor is selected which satisfies the criterion. The car is caused to stop at fewer than all the identified input floors and identified destination floors during the journey.
Abstract:
An exemplary method of controlling an elevator system includes determining that a new passenger requests elevator service from a departure floor to a destination floor. Any candidate elevator cars are ranked. A number of stops for each assigned passenger for a ranked candidate elevator car is determined if the new passenger were assigned to that car. A determination is made whether any ranked candidate elevator car is a qualified car that can accept the new passenger and limit a number of stops for each passenger assigned to that car to a desired maximum number of stops. The new passenger is assigned to a qualified car that has a most favorable ranking of any qualified cars.

Abstract:
An exemplary method for handling passenger requests during elevator system modernization includes modernizing elevator cars over time. The modernized elevator cars are capable of servicing destination requests placed outside of an elevator car and include an indication of a desired destination. The exemplary method includes assigning an elevator car to respond to a new pending destination request according to a selected criterion for selecting between a modernized elevator car and an elevator car that has not yet been modernized. The method includes automatically updating the selected criterion responsive to a change in a number of modernized elevator cars. A percentage of the elevator cars that are not yet modernized are reserved and new pending requests are assigned to a modernized elevator car if a percentage of modernized cars plus the reserved percentage is greater than a current percentage of pending requests assigned to modernized elevator cars.

Abstract:
An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators.
Abstract:
An elevator system including a car call registration device by which an elevator user registers a car call before riding on a car and a group supervisory controller with a building specification data storage section in which building specification data including specially-assigned floors is stored. Further, a specially-assigned floor judgment section judges whether a departure floor is a specially-assigned floor when a car call is registered, and a traffic condition judgment section judges the traffic condition of elevators within a building. A car assignment is performed based on the traffic condition judgment section judging by the specially-assigned floor judgment section that the departure floor is a specially-assigned floor, and a car assignment is performed based on a building specification stored in the building specification data storage section when the specially-assigned floor judgment section judges the departure floor is not a specially-assigned floor.
Abstract:
The present invention pertains to a method for optimal routing of the elevators in an elevator system in a situation where the supply power received by the system is limited e.g. due to emergency power operation. In the invention, routes are optimized by using a cost function to which has been added a term containing the summed instantaneous power consumed. Power consumption is monitored in real time, and the elevators need a start permission from the control system. A route alternative that exceeds the power limit is penalized in the cost function by a so-called penal term. With the elevator routing obtained as a result, the instantaneous power consumed by the system remains continuously below the set power limit. Some call can thus be postponed to be served later. By the method of the invention, the number of elevators serving passengers in an emergency power situation can be varied dynamically.
Abstract:
In an elevator system floors each include: a hall registration device that places a plurality of car calls for moving a car to destination floors different from one another; and a display device that displays the car that has been assigned the plurality of car calls. A limit value setting mechanism sets, for each of the plurality of floors separately, a limit value for limiting a count of the plurality of car calls that can be assigned to the same car. A count-up mechanism obtains, when a new car call is made, a call count of each car by a given method, based on information about the plurality of car calls that have been assigned to the car. A candidate car selector compares the limit value set to a floor where the new car call is made and the call count of the each car, to thereby select, as a candidate car, the car to which the new car call can be assigned from among the cars.
