Design and Control of Lift Systems Using Expert Systems and Traffic Sensing

We describe an approach to lift traffic analysis and control based on traffic sensing and rule-based expert systems. The system is implemented using standard packages, based on a spreadsheet in the first instance. Simulated input traffic is generated and dynamically linked to the simulator, showing car movements. An expert system linked to a traffic sensing system continuously calculates optimum car movements. Practical aspects of the implementation are discussed.
