ABSTRACT:
An elevator control apparatus for moving free elevator cages to optimal stand-by floors determined according to a plurality of fuzzy rules of if-then format. A learning function is employed for altering the parameters of the fuzzy rules based on statistics of past traffic patterns over a pre-determined time period. Free elevator cages are detected by an operation control element and then moved to optimal stand-by floors. A stand-by control element responsive to fuzzy rules generates a signal directed to the operation control element for initiating movement of the free elevator cages.
