Abstract
The invention discloses a controller workload prediction method and system. The method comprises a first step of determining a back propagation (BP) neutral network topology structure, collecting sector traffic flow state index samples of different times, and building a sample set; a second step of optimizing a weight and a threshold of a BP neutral network by use of a genetic algorithm, performing network training, and outputting an optimized BP neutral network; a third step of predicting the index of the controller workload through the optimized BP neutral network of the second step according to the input real-time data of the sector traffic flow state index; and a fourth step of responding to a warning if a result of predicted index of the controller workload meets a preset condition. Through adoption of the method, the reliability of the prediction result of the controller workload can be improved, actual demands of an air traffic control unit on real-time prediction and warning for the controller workload can be met, and the method can provide data support for improvement of operation management level and optimization of the controlled airspace structure.
Description
technical field [0001] The invention relates to the field of aviation, in particular to a method and system for predicting the workload of controllers. Background technique [0002] With the development of the air transport industry, in order to ensure the safety and order of various flight activities, the air traffic control service came into being and was continuously developed and improved until it became mature in the 1980s. The main content of modern air traffic control services is: Air traffic controllers (referred to as "controllers", the same below) rely on modern communication, navigation, and surveillance technologies to manage and control aircraft under their jurisdiction, coordinate and guide their movement paths and Mode to prevent collisions between aircraft in the air and collisions between aircraft and obstacles in the maneuvering area of the airport, and maintain and speed up the orderly flow of air traffic. The main job of the controller is to closely mo...
