Abstract
In an elevator system in which an elevator car serves a plurality of floors in response to hall calls and cage calls, the number of, for example, up hall calls originated from, for example, the 2nd floor is counted, and the number of cage calls, classified by destination floors, registered in the elevator car after the elevator car has served each of the up hall calls is also counted. The count of the hall calls and the count of the cage calls classified by destination floors are compared with each other, and, on the basis of the result of comparison, the probabilities of origination of cage calls, classified by destination floors, which will be registered in the elevator car after the elevator car has subsequently served a new up hall call which would be originated from the 2nd floor, are calculated for forecasting future cage calls.
