Abstract
The traffic mode of an elevator system is set according to the number and frequency of passengers departing and arriving at a building lobby. The traffic mode is expressed as a fuzzy logic set having a term indicative of up peak mode, a term indicative of down peak mode, and a term indicative of off peak mode. The degrees of membership of each term are indicative of the degrees to which the elevator system exhibits characteristics of the respective modes.
