In a group-control for an elevator system with plural elevator cages, when a hall call is generated, evaluation values of all of group-controlled cages with respect to the generated hall call are calculated by a predetermined evaluation function, as expressed by the following formula: phi n=(WT-kpZp+kcTc+kLLL-KzZZ-ksZs)n n=1, 2, . . ., N wherein N denotes the total number of group-controlled elevator cages, WT, Zp, Tc, LL, and Zs represent evaluation indexes of a waiting time, an equal time-interval operation preferential zone, a riding time, a cage-load factor, a first-arriving cage preferential zone and a stop call, and kp, kc, kL, kz and ks represent control parameters for the last five of the evaluation indexes above, respectively. The generated hall call is allotted to a cage having a minimal evaluation value calculated by the aforesaid evaluation function. The control parameters are selected and set at appropriate values in accordance with a manner of use of a building installed with the elevator system.
