Abstract (en)

[origin: EP1873106A1] An elevator group-management-control device is provided in which the device selects an elevator car, taking into account the number of floors that the elevator car skips and a passenger's walking time, when a call-register device is placed away from an elevator lobby. The elevator group-management-control device includes: a walking-time estimating means 9 for estimating a walking time for a passenger to walk to the elevator lobby; a predictive calculating means 10 for predictively calculating a time until each elevator car 2 arrives at the lobby; a waiting-time conversion means 11 for converting into an actual waiting time or a lost time the difference between the predicted time until the elevator car 2 arrives, calculated predictively by the predictive calculating means 10, and the estimated actual waiting time; an evaluation-value calculating means 12 for calculating an evaluation value that increases with increase in the actual waiting time or the lost time; an assigning means 13 for determining, as an assigned elevator car, an elevator car for which evaluation value has been calculated to be minimum, by the evaluation-value calculating means 12; an operation control means 15 for instructing the assigned elevator car to move to the floor from which the call has been registered; and a door opening/closing means 14 for keeping open the door 2 of the elevator car assigned until the estimated walking time has elapsed after it is opened.
