Abstract

The invention discloses a maintenance task human factor fault modeling analysis method in a space man-machine system cabin, which comprises the following steps of: analyzing and decomposing maintenance tasks, and determining group cognitive behaviors and common performance conditions related to the maintenance tasks; based on the multiplicative group cognitive behavior, establishing a multiplicative group cognitive process model, and determining cognitive behavior cognitive failure modes and failure probability basic values; based on the common performance condition, refining the behavior influence factors, and calculating to obtain a common performance condition level and a multiplication group cognitive process total weight factor; and sequentially calculating to obtain a basic human error probability, a conditional human error probability and a joint human error probability. According to the method, the correlation among influence factor intervention, maintenance task decompositionand maintenance subtasks is considered, the basic human error probability, the conditional human error probability and the united human error probability are calculated more accurately, reference is provided for model designers to predict risks in advance and take response measures, and safe operation of a space man-machine system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of system safety, and in particular relates to a human error modeling and analysis method for maintenance tasks in a cabin of a space man-machine system. Background technique [0002] Human Reliability Analysis (HRA) originated in the 1950s and has a history of more than 50 years. In the late 1950s and early 1960s, people began to discuss the impact of human error on system security and reliability. Today, human error has become one of the key factors affecting system security. [0003] The development of human factor reliability analysis methods can be roughly divided into two stages. In the first stage, the HRA method focuses on the study of human behavior theory and error classification, and forms a human error probability prediction technology similar to equipment reliability analysis ( Technique of Human Error Rate Prediction, THERP) and other methods. The HRA method in the second stage puts more emph...
