ABSTRACT:
An elevator system includes a controller that uses one of a plurality of fuzzy logic algorithms for assigning an elevator car to service a passenger request. One example uses a passenger's desired destination as indicated by the passenger service request prior to the passenger entering an elevator car. One example includes multiple fuzzy logic algorithms, each corresponding to a particular relationship between an elevator car's current assignments, a passenger's desired destination, a source landing of the passenger's request, or a combination of them.
