A Methodology for Analysis of Dependency between Operators in Digital Control System in a Nuclear Power Plant

摘要: 在数字化控制系统中,操纵员行为之间的相关性模式与传统控制室不同。为了评价数字化控制系统中操纵员行为之间的相关性,提出了基于模糊逻辑的操纵员相关性分析方法。首先通过对数字化控制系统中的人因特征的分析,识别操纵员行为相关性的影响因素,建立相关性分析模型,然后基于模糊逻辑方法建立数字化控制系统中操纵员之间的相关性分析方法。该方法不仅能模拟模糊的和不确定性的知识,而且对推理过程及结论的获得给出清晰的解释,具有可追溯性和重复性。Abstract: The dependence between actions of the operators is more prevalent in the digital control system.Fuzzy logic-based approach is provided to evaluate the dependence of operators’ actions.Firstly,through the analysis of the characteristics of human factors in the digital control system,the factors influencing the dependence level of operators’ actions are identified,and the analytical model of dependence is constructed.Then,the methodology for analysis of dependency between actions of the operators is established based on the fuzzy logic approach.This method can not only simulate the vague and uncertain knowledge,but also give a clear explanation of the origin of the results and its reasoning process by tracing the reasoning steps.There-fore,there is traceability and repeatability in the proposed method.
