Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and the embodiments.

[0026] Based on the fact that the related technology does not consider the influence of the operator’s own contextual factors and their influence causality, which may bring about the possibility of recalculating the influence, and the problem of the possibility of incorrect estimation of the state assessment error probability, the present invention is implemented The example provides a reliability analysis method for operator status evaluation. The process of the method is as follows figure 2 As shown, it includes step S202 to step S206:

[0027] Step S202: Determine multiple PSFs to be used, where PSFs are used for state evaluation;

[0028] Step S204: Determine the association relationship between each PSF of the multiple PSFs and other PSFs except itself, and the association relationship between each PSF and the state evaluation reliability node...

Abstract

The invention discloses an analyzing method and an analyzing device for operator state assessment reliability. The method comprises the steps of determining a plurality of PSFs, wherein the PSFs are used for state assessment; determining the incidence relation between each PSF and all the other PSFs in the plurality of PSFs except the PSF itself and the incidence relation between each PSF and a state assessment reliability node; and according to the incidence relations, establishing an analyzing model of the operator state assessment reliability based on the PSF causal relations so as to analyze the reliability of an operator. Through the application of the analyzing method and the analyzing device, the problems that in the prior art, due to the fact that influences of situational environmental factors to the operator and influence causal relations of the factors are not considered, the possibility of repetitive computation of the influences is brought, and false assessment can be caused to state assessment miss probability are solved, therefore a qualitative and quantitative method is provided for analyzing the operator state assessment reliability and strategies are provided for lowering operator state assessment failure probability for an electric power plant.

Description

Technical field [0001] The present invention relates to the field of nuclear power plant detection and human factor reliability analysis, and more specifically, 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 plans and response execution decisions. The series of behavioral processes is called Situation assessment or situation awareness (SA). The operator's correct state assessment of abnormal events is essential for the correct response of the operator's behavior. [0003] So far, Endsley’s state assessment model established in the journal “Human factors” published in 1995 called “Toward a theory of situation awareness in dynamic” divides it into three levels: recognition o...
