Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
307 words
A method of dispatching a plurality of elevator cars in a building comprising: providing a plurality of signals representing a basic fuzzy set for a single passenger including basis elements of the possible amounts of weight which one passenger may add to an elevator car and corresponding membership values indicative of the likelihood that one passenger has added the related amount of weight to the car ; providing a plurality of signals representing a factor fuzzy set for a single passenger including basis elements indicative of additional amounts of weight which each passenger may have compared with the likelihood of weight expressed in said single passenger fuzzy set, including basis elements of possible additional passenger weight and corresponding membership values indicative of the likelihood of a passenger having the related additional weight; providing a plurality of signals representing a plurality of composite fuzzy sets, one for each possible number, N, of passengers which may be in the elevator, each reflecting N times the fuzzy summation of said basic fuzzy set and said factor fuzzy set; providing a weight signal indicative of the weight of passengers in an elevator; providing a plurality of signals representing a passenger count fuzzy set in which each of the terms corresponds to a related term of one of said composite fuzzy sets which has a basis element equaling the weight indicated by said weight signal, each term of said passenger count fuzzy set having a basis element equaling the number of passengers corresponding to the composite fuzzy set of the related term and a degree of membership the same as the degree of membership of said related term; and dispatching elevators to provide service in said building in response to a process using the signals of said passenger fuzzy set to provide corresponding representations of the number of passengers in said elevator.
