Abstract
Abstract A control system for operating a transportation system including a plurality of vehicles, such as elevators, is disclosed wherein a history of the past performance of the transportation system is stored. This history is analyzed by a digital computer, and the operating mode of the transportation system is changed in accordance with the analysis in order to optimize the performance of the system.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
In a transportation system including a plurality of vehicles serving a plurality of stations and means for operating said vehicles, an improved adaptive control system comprising in combination: , a. sensor means for producing signals representing the performance of said vehicles over a period of time, b. a digital computer coupled to said sensor means for storing said signals and programmed to analyze said signals to produce a record of control signals for Optimizing the operation of said vehicles in accordance with the analysis, and c. means responsive to said record for controlling said operating means in accordance with said record and said sensor means.
Claim 2
Dependent Claim
105 words
In a transportation system including a plurality of vehicles serving a plurality of stations and means for operating said vehicles, an improved adaptive control system comprising in combination: , a. sensor means for producing signals representing the performance of said vehicles over a period of time, b. a digital computer coupled to said sensor means for storing said signals and programmed to analyze said signals to produce a record of control signals for Optimizing the operation of said vehicles in accordance with the analysis, and c. means responsive to said record for controlling said operating means in accordance with said record and said sensor means.
Claim 3
Dependent Claim
26 words
The improved control system of claim 1 wherein said vehicles are elevators and said stations are floors in a building in which said elevators are operating.
Claim 4
Dependent Claim
73 words
The improved control system of claim 2 wherein said sensor means comprises means for producing first signals representing the demand for an elevator at each floor at selected time intervals, said computer being responsive to said first signals to produce a record for controlling said operating means to return to a floor, at time intervals during which the demand exceeds the capacity of an elevator, an elevator for which there is no demand.
Claim 5
Dependent Claim
90 words
The improved control system as defined in claim 3 wherein said sensor means further comprises means for producing second signals representing the traffic entering and leaving each elevator at different pairs of floors at selected time intervals, said computer being responsive to said second signals for producing a record for controlling said operating means so that at least one elevator is operated in an express mode directly between two floors during those time intervals at which the entering and leaving traffic, respectively, between those two floors, exceeds a predetermined volume.
Claim 6
Independent Claim
85 words
A method of optimizing the performance of a transportation system including a plurality of vehicles operating among a plurality of vehicle stations comprising the steps of: a. continuously sensing over a period of time signals representing the performance of the system, b. storing the signals, c. analyzing the stored signals to derive a history of the system performance over the period of time, and d. modifying the operation of the vehicles in accordance with the performance history to optimize the performance of the transportation system.
Claim 7
Independent Claim
85 words
A method of optimizing the performance of a transportation system including a plurality of vehicles operating among a plurality of vehicle stations comprising the steps of: a. continuously sensing over a period of time signals representing the performance of the system, b. storing the signals, c. analyzing the stored signals to derive a history of the system performance over the period of time, and d. modifying the operation of the vehicles in accordance with the performance history to optimize the performance of the transportation system.
Claim 8
Independent Claim
100 words
A method of adaptively controlling the mode of operation of a plurality of vehicles serving a plurality of stations in a transportation system comprising the steps of: a. continuously sensing over a period of time first signals representing the demand for a vehicle at each of said stations, b. establishing a predetermined capacity for each of said vehicles, c. comparing the demand at each station with the predetermined capacity, and d. when the demand at a station exceeds the predetermined capacity of a vehicle, controlling the mode of operation of the vehicle to optimize the performance of the transportation system.
Claim 9
Independent Claim
100 words
A method of adaptively controlling the mode of operation of a plurality of vehicles serving a plurality of stations in a transportation system comprising the steps of: a. continuously sensing over a period of time first signals representing the demand for a vehicle at each of said stations, b. establishing a predetermined capacity for each of said vehicles, c. comparing the demand at each station with the predetermined capacity, and d. when the demand at a station exceeds the predetermined capacity of a vehicle, controlling the mode of operation of the vehicle to optimize the performance of the transportation system.
Claim 10
Dependent Claim
33 words
The method of claim 6 wherein the controlling step further comprises returning a vehicle for which there is no demand to a station at which the demand exceeds the capacity of a vehicle.
Claim 11
Dependent Claim
86 words
The method of claim 7 further comprising the steps of: a. continuously sensing over a period of time second signals representing the traffic entering and leaving a vehicle at each station b. comparing second signals representing traffic entering and leaving a vehicle at different pairs of stations, and c. when traffic entering and leaving two stations, respectively, exceeds a predetermined volume, further controlling the mode of operation so that at least one vehicle is placed in an express mode to travel directly between the two stations.
