Method of assigning a car to service a hall call in an elevator system |
(57) In a elevator system, the utility of assigning a car to service a hall call is determined
by using an assignment utility fuzzy set having basis elements corresponding to the
cars of the elevator system and degrees of membership corresponding to the utility
of assigning the associated car to the hall call.
The assignment utility fuzzy set is formed in accordance with a method comprising
the step of constructing a plurality of performance fuzzy sets, each set corresponding
to a particular elevator performance indicator and each term of each set representing
the estimated value of the particular performance indicator which corresponds to servicing
the hall call with a particular car.
