ABSTRACT:
The utility of assigning each car of an elevator system to service a hall call is determined by estimating the performance of each elevator car using a plurality of performance criteria. The performance criteria are then scaled by values indicative of the customer preferences for elevator system performance in order to form a plurality of scaled performance fuzzy sets. An assignment utility fuzzy set is formed from terms of the scaled performance fuzzy sets. The utility of assigning each car to service a particular hall call is then set equal to the maximum value of the degrees of membership of all of the terms of the scaled performance fuzzy sets. Alternatively, the utility of assigning each car to service a particular hall call can be set equal to the minimum value of the degrees of membership of all of the terms of the scaled performance fuzzy sets.
