Abstract
Fuzzy sets indicative of likelihood of additional weight elevator passengers may have in a given country compared with a standard international low passenger weight, indicative of packages which may be carried up at certain times of day or carried down at certain times of day by passengers in the elevator, and indicative of the weight of additional clothing which may be worn due to different seasons in temperate climates are all added to a basic single passenger fuzzy set so as to more accurately reflect the likely weight of a single passenger. From this are derived fuzzy sets for any number of passengers which may possibly occupy an elevator, which in turn are utilized to provide a passenger fuzzy set indicative of a given weight of the elevator having been caused by various numbers of passengers. Processing details are also disclosed.
