Abstract:
The present invention discloses a method for controlling an elevator system. In the method an elevator is allocated for the use of a passenger in a first optimization phase in such a way that a first cost function is minimized, a second optimization phase is performed, in which the route of the allocated elevator is optimized in such a way that a second cost function is minimized.
Abstract:
In a group supervisory control apparatus for elevators, car excluding means (31) for excluding a car based on door-open time period of an allocation candidate selecting section (130) receives information of a scheduled door-open waiting time period and a prediction boarding time interval with respect to each of a plurality of cars, from an allocation candidate selection index calculating section (120). The car excluding means (31) for excluding a car based on door-open time period uses the prediction boarding time interval and the scheduled door-open waiting time period for determining whether or not to exclude each of the plurality of cars from selection of an allocation candidate for a new landing call performed by a user.

Abstract:
Floors are each provided with: 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. Limit value setting means 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. Count-up means obtains, when a new car call is made, a call count of the each car by a given method, based on information about the plurality of car calls that have been assigned to the car. Candidate car selecting means 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.
Abstract:
In a vertically movable elevator group management control apparatus for control of a plurality of transversely shiftable cars among plural shafts, control is done by storing route data with respect to each said car, generating target floor data including a target floor, based on car call data obtained in correspondence with each said car and station call data as obtained correspondingly to each floor, estimating the time taken for said car to reach said target floor, based on at least said route data, said target floor data and said car call data, and assigning a certain car to a certain floor call, based on the estimated arrival time.
