Nuclear power plant organization behavior reliability assessment method, device and equipment

Abstract

The invention discloses a nuclear power plant organization behavior reliability assessment method, device and equipment. The method comprises the steps of obtaining an organization error causal modelobtained through scene environment analysis under a preset scene and behavior forming factors influencing organization behaviors in the model and a causal influence relation of the behavior forming factors; obtaining the state level of the behavior forming factor; according to a preset organization behavior reliability assessment model, obtaining a fault probability of the organization behavior tobe assessed by utilizing the state level so as to assess the reliability of the organization behavior, wherein the preset organization behavior reliability assessment model is a model containing corresponding relations between different state level levels of the behavior forming factors and organization behavior fault probabilities. Namely, the state grade level of the behavior forming factor isutilized, the error probability of the to-be-evaluated organization behavior is obtained according to the preset organization behavior reliability evaluation model, quantitative evaluation on the organization behavior reliability is achieved, and theoretical and data support is further provided for prevention of organization errors and risks.

Description

technical field [0001] The invention relates to the technical field of human factor research, in particular to a method, device and equipment for evaluating the reliability of nuclear power plant organizational behavior. Background technique [0002] The investigation of catastrophic accidents in complex industrial systems has shown that organizational errors are the root cause of human errors. If organizational errors are not detected and corrected, accidents may occur and bring catastrophic consequences. [0003] From the definition of organizational failure, in a complex-sociotechnical system like a nuclear power plant, a wide variety of potential organizational failures can occur due to the complexity of the organization and the system. In order to identify the risk of organizational failure to events and accidents, an assessment of the probability of possible organizational failure is required. However, there are very few studies on the evaluation methods of organizati...

Problems solved by technology

However, there are very few studies on the evaluation methods of organizational failure probability, which basically consider the influence of organizational factors on human reliability, but do not quantitatively estimate the probability of organizational failure, making it difficult to evaluate the reliability of organizational behavior
