    • Each car in a group of elevator cars in a building is determined to be available or not depending on whether it is assigned in the group, whether it is the only delayed car, whether it is fully loaded without intervening car calls which comprise all the car calls, whether it has intervening hall calls, and whether other cars in the group are fully loaded with or without some chance of offloading passengers before reaching a call to be assigned. Among available cars, assignment is made based on each car's membership in fuzzy sets relating to low, medium or high delay in that car responding to the call and each car's membership in fuzzy sets indicative of the extent to which assignment of that car will have no adverse effect or a very high adverse effect on the response to already-assigned hall calls. The call is assigned to the car with the highest summation of weighted memberships in the fuzzy sets.

    • In one embodiment, fuzzy sets indicative of the degree to which the time since the last passenger boarded an escalator can be deemed to be zero, a very long time, or something in between, are combined with fuzzy sets indicative of the extent to which the maximum number of passengers in a recent temporal or cyclic period can be deemed to be a zero passenger, a very large group, or something in between. In another embodiment, fuzzy sets indicative of the degree to which the time since the last passenger exited an empty escalator can be deemed to be nearly zero, a very long time, or something in between, are combined with fuzzy sets indicative of the degree to which the maximum group of passengers on the escalator at any time since the last time it was empty can be deemed to be a single passenger, a very large group, or something in between. T-norms (functions for combining the pair of fuzzy sets) are used to select recommended target speeds; weighted averaging of more than one recommended target speed is used to defuzzify the result to achieve an ultimate target speed, except in the second embodiment, which tailors the speed of the escalator to the current traffic level where the target speed is always maximum if the escalator is occupied and which judiciously slows an empty escalator.
    • 在一个实施例中,指示自上次乘客登上自动扶梯以来的时间的模糊集合可以被认为是零,很长时间或其间的某些事物与模糊集合组合,该模糊集指示 在最近的时间或循环期间,乘客的最大数量可以被认为是零乘客,非常大的群体,或两者之间的东西。 在另一个实施例中,指示自上次乘客离开空自动扶梯以来的时间的模糊集合可以被认为几乎为零,很长时间或其间的某些事物与表示程度的模糊集合 自动扶梯上次最长时间以来的最大乘客数量可以被认为是一名乘客,一个非常大的群体,或者两者之间的东西。 T标准(用于组合一对模糊集的功能)用于选择推荐的目标速度; 除了在第二实施例中,如果自动扶梯将自动扶梯的速度调整到目标速度总是最大的当前交通水平,则使用超过一个推荐的目标速度的加权平均来对结果进行去模糊以达到最终目标速度 被占用,明智地减缓了一个空的自动扶梯。

    • An uncertainty filter is provided with input data which is indicative of a fuzzy logic set having basis elements corresponding to elevator cars of an elevator system having degrees of membership associated therewith corresponding to the utility (suitability) of assigning the associated car to service a hall call. The uncertainty filter chooses a car corresponding to the term from the set having the highest degree of membership. The choice can be delayed until; a predetermined amount of time has passed; the degree of membership exceeds a predetermined amount; or the degree of certainty (the degree of membership of the chosen car over the sum of degrees of membership of the other cars) is more than a predetermined amount; or until either the degree of membership or the degree of certainty meets a value which varies as a function of time from when a hall call was registered.

    • Elevator cars (10) have floors (11) including a matrix of elements (12) including a weight sensing cell (18) to determine weight distribution in the car for controlling the position of a moveable hitch (33-36) on the car and for allocating calls to the cars depending upon the weight distribution. Transmitters (26) borne by passengers (25) transmit identification portions, and may also transmit personal preferences of the passenger with respect to the elevator ride. The system may store personal preferences in a data base indexed by personal identification numbers, limiting the required transmission to only the identification number. Correlation (FIG. 4) of identification numbers with the cell indicating by weight where a passenger is located may be achieved in each element of the floor or in a controller. A group controller (22) may allocate calls based upon weight distribution and/or preferences of passengers.

    • The utility of assigning each car of an elevator system to service a hall call is determined by estimating the performance of each elevator car using a plurality of performance criteria. The performance criteria are then scaled by values indicative of the customer preferences for elevator system performance in order to form a plurality of scaled performance fuzzy sets. An assignment utility fuzzy set is formed from terms of the scaled performance fuzzy sets. The utility of assigning each car to service a particular hall call is then set equal to the maximum value of the degrees of membership of all of the terms of the scaled performance fuzzy sets. Alternatively, the utility of assigning each car to service a particular hall call can be set equal to the minimum value of the degrees of membership of all of the terms of the scaled performance fuzzy sets.
