Abstract
For any given sensed load weight in an elevator car, the union (30-36) of a fuzzy set (FIG. 2) indicative of the likelihood of possible number of male passengers causing the sensed weight, taking into account the relative mix of males in the total population of the building (12-22) with a fuzzy set (FIG. 4) indicative of the likelihood of possible number of female passengers causing the sensed weight, taking into account the relative mix of females in the total population of the building (14-24), forms a passenger count fuzzy set (FIG. 5) indicative of the likelihood of a given number of passengers corresponding to each sensed or discernible elevator load weight for use in dispatching of elevator cars. A lookup table may be established (FIG. 7) for all possible weights.
