Embodiment Construction

[0100] The present invention is a human error mechanism modeling method considering path dependence. The British Harrier aircraft crash case is selected for analysis, and the case description is as follows.

[0101] In 1997, the British "Harrier" fighter jet crashed. The process of the accident was that the pilot found that the engine temperature sensor alarmed during the approach process, indicating that the temperature of the nozzle was too high. In fact, the engine temperature sensor failed, resulting in a false alarm. Pilots need to judge the engine status based on engine temperature, speed, thrust and other information. In this case, the pilot judged the engine to be faulty and tried to fix the nozzle temperature, but was unsuccessful. In the end, the pilot chose to eject and escape in the event of an "difficult to repair" engine failure, causing the plane to crash.

[0102] In the present invention, a human error mechanism modeling method considering path dependence is ...

Abstract

A human error mechanism modeling method considering path dependence comprises the following steps that 1, human-computer interaction tasks are analyzed, and bottom layer operation types and specific cognitive functions called by the bottom layer operation types are clarified, including basic task analysis, cognitive behavior analysis and human error mode analysis; 2, defining an abnormal information mode, and judging the correlation between the abnormal information mode and a human error mode caused by cognitive confusion; 3, determining basic cognitive resource requirements of each task; 4, evaluating six stable performance forming factors, namely the PSFs level; 5, performing correlation adjustment on the human error probability after PSFs adjustment according to cognitive overload and cognitive confusion so as to obtain a human error probability considering path dependence; Through the above steps, a human error mechanism model is provided, the correlation between human errors and other abnormal events in the same human-computer interaction evolution path is established, and on the basis, the problem of influence of path dependence on the human error probability is solved.

Description

technical field [0001] The invention provides a human error mechanism modeling method considering path dependence, which is a modeling and quantification method in the field of man-machine system safety analysis, and focuses on solving the problem of the influence of human-computer interaction evolution path on human error from the information level . Background technique [0002] Man Machine Interaction (MMI) is one of the most common and typical scenarios in engineering practice. With the continuous improvement of system hardware automation and reliability, the man-machine system (Man Machine System, MMS) has higher and higher requirements for human-computer interaction, and man-machine interaction errors have become a weak link in the overall security of the man-machine system. Accident investigations show that the main cause of human-computer interaction errors is cognitive errors in the process of human-computer interaction. In fact, cognitive errors are affected by h...
