Embodiment Construction

[0061] The present invention is a potential fault analysis method based on PFMEA and HRA methods, and the process is illustrated by taking the potential fault analysis in the weapon mounting task stage of a certain type of airborne weapon system as an example. The airborne weapon system has typical multi-stage mission characteristics, which are mainly divided into weapon system maintenance, mounting, flying, launching and unloading stages. There is a complex human-computer interaction process in the maintenance or mounting phase, and the potential faults caused by it may be activated during the flight or launch phase, eventually leading to serious accidents.

[0062] The personnel performance of tasks in the maintenance or mounting phase is affected by the coupling of equipment and environmental conditions, and the operation actions of personnel in the process have a certain correlation. The present invention fully considers the above-mentioned influence relationship, which can...

Abstract

The invention provides a potential fault analysis method based on PFMEA and HRA methods. The potential fault analysis method comprises the following five steps: 1, task analysis; 2, abnormal mode and abnormal reason analysis; 3, quantification of the occurrence probability of the abnormal function mode; and 4, risk priority number calculation and potential fault identification. Through the steps, the problems of man-machine separation and difficulty in quantification of the potential fault probability in the PFMEA method are solved, the man-machine loop coupling effect and the human error correlation are considered by combining the CREAM and THERP methods in the HRA, and quantification of the human error probability and the potential fault occurrence probability is realized.
