Abstract

The invention belongs to the technical field of system engineering reliability analysis, and relates to a human error analysis method and system, a computer device and a storage medium. The method comprises the steps of obtaining score values of a plurality of performance factors, wherein the performance factor is a performance influence factor corresponding to each sub-task in a task scene; calculating a score value according to a preset quantization processing mode; obtaining a membership degree value and a confidence degree; inputting the membership degree value and the confidence coefficient into a preset Bayesian network model, to obtain a human error probability value corresponding to the task scene. Human error probability prediction is more accurate, the risk point of the human error probability in the whole operation task can be further provided for subsequent master control room and man-machine interface designers, a theoretical basis is provided for subsequent improved design, and nuclear power station safety operation safety is improved.

Description

technical field [0001] The present application relates to the technical field of system engineering reliability analysis, in particular to a human error analysis method, system, computer equipment and storage medium. Background technique [0002] With the introduction of digital technology in the main control room of nuclear power plants, the operator's task types and situational environment have changed, which affects performance and may lead to human error. For example, in terms of information acquisition methods, the analog control room system obtains information at a fixed position through analog instructions, while the digital control room system is replaced by VDU display screens. Information acquisition needs to be searched and invoked. The state of the situation has changed significantly. Therefore, effective evaluation methods should be adopted to review the digital human-machine interface before it is actually applied in engineering projects. Among them, Human Re...
