Problems solved by technology
[0006] The present invention aims to provide a reliability analysis method and device for operator state evaluation, so as to solve the problem that the relevant technology does not consider the influence of the situation and environmental factors on the operator itself and their causal relationship, which may lead to double calculation and other factors. The possibility of impact, the problem of wrong estimation of the probability of state assessment errors

Embodiment Construction
[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0026] Based on the fact that the relevant technology does not consider the influence of the situational environmental factors and their influence causality on the operator itself, which may bring the possibility of double calculation of its influence, and may cause wrong estimation of the error probability of state assessment, the present invention implements The example provides a reliability analysis method for operator status evaluation, the flow of the method is as follows figure 2 As shown, including step S202 to step S206:
[0027] Step S202, determining multiple PSFs to be used, wherein the PSFs are used for state assessment;
[0028] Step S204, determining the association relationship between each PSF and other PSFs except itself among the multiple PSFs, and the association relationship between each PSF and the status eval...

Disclosed are a reliability analysis method and device for the state evaluation of an operator. The method comprises: determining a plurality of PSFs to be used, wherein the PSFs are used for the state evaluation; determining correlations between each PSF in the plurality of PSFs and other PSFs except for themselves, and correlations between each PSF and a reliability node for the state evaluation; and establishing a reliability analysis model of the state evaluation of the operator on the basis of a PSF causation in accordance with each of the above-mentioned correlations to analyze the reliability of the operator. By using the present invention, the problem of possibly estimating the failure probability of the state evaluation by mistake because of the influence of situation environmental factors on the operator himself and the influence causations thereof are not considered in the related art, and thus the possibility that repetitive computation of the influences thereof may be caused is solved; and then, a qualitative and quantitative method is provided for the reliability analysis of the state evaluation of the operator, and a countermeasure is provided for a power plant to reduce the failure probability of the state evaluation of the operator.
Description
technical field [0001] The invention relates to the fields of nuclear power plant detection and human factor reliability analysis, and more specifically, relates to a reliability analysis method and device for operator state evaluation. Background technique [0002] When an abnormal state occurs in a nuclear power plant, the operator will construct a reasonable and logical explanation based on the state parameters of the nuclear power plant to evaluate the state of the power plant as the basis for subsequent response planning and response execution decisions. A series of behavioral processes is called a situation assessment (Situation assessment or situation awareness, referred to as SA). The operator's correct state assessment of abnormal events is crucial to the correct response of the operator's behavior. [0003] So far, Endsley has divided it into three levels in the state assessment model established in the journal "Human factors" titled "Toward atheory of situation a...
