Embodiment Construction
[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0055] In the prior art, because the process of obtaining reliability data is very difficult, and human reliability analysis has complexity, ambiguity, subjectivity and uncertainty, the assessment results of the team's situational awareness reliability are not accurate enough. For this reason, the present invention obtains and the status level of the target behavior influencing factors through the preset team and group situation awareness reliability model that...

The invention discloses a digital nuclear power plant team scene consciousness reliability assessment method, device and equipment and a medium. The method comprises the steps of obtaining a target behavior influence factor which directly influences the team scene consciousness reliability and a state level of the target behavior influence factor; obtaining a team scene consciousness error probability corresponding to the state level by using a preset team scene consciousness reliability model so as to evaluate the team scene consciousness reliability, wherein the preset team scene consciousness reliability model is a model which is constructed by using a fuzzy logic method and contains corresponding relationships between different state level levels of target behavior influence factors and team scene consciousness error probabilities. Therefore, the quantitative evaluation of the team scene consciousness reliability is realized based on the preset team scene consciousness reliabilitymodel constructed by using the fuzzy logic method, the subjectivity, complexity and uncertainty of expert judgment are reduced, and theoretical support is further provided for identifying the team scene consciousness error risk.
Description
technical field [0001] The invention relates to the technical field of human factor research, in particular to a reliability evaluation method, device, equipment and storage medium for situational awareness of a digital nuclear power plant team. Background technique [0002] Any human activity in the system is inseparable from the situational environment at that time, and human error behavior is usually caused by the situational environment. Human cognition of the situational environment, i.e., situational awareness, as a cognitive behavior used to explain what and how is happening between the operator and the environment in complex human-machine systems, is a prerequisite for effective decision-making and high performance . The monitoring of the normal operating state of the digital nuclear power plant system and the successful handling of the abnormal state often require team members to coordinate and cooperate to complete. If an individual situation awareness error occur...
