Abstract

A procedure for allocating the calls entered via landing call devices of the elevators in an elevator bank forms several allocation options. Each allocating option contains, for each active landing call, a call data item and an elevator data item which together are used to determine which elevator should service the call. The value of a cost function is calculated for each allocation option; one or more of the allocation options is repeatedly changed with respect to at least one data item, and the values of the cost functions of the new allocation options are calculated. Based on the values of the cost functions, the best allocation option is selected and the active elevator calls are allocated to the elevators in the elevator bank accordingly.
