基于人因可靠性的核电厂数字化人机界面功能单元数量优化方法

摘要

T he quantity of components of a function block in digital human‐computer interface of nuclear power plant brings heavy burden to operators and influences human error event to occur .In this paper ,a complete optimizing process for the quantity of pa‐rameters in function block was established ,and a few key points in the complete optimi‐zing process were discussed . Using dynamic fuzzy method , the fuzzy segment was formed by quantity of factor ,the middle search fetching method that could well improve search performance for fuzzy quantity of segments included quantity of optimization factor was established ,and an error affinity probability function was proposed as well . T he experimental results show that the middle search fetching method of fuzzy quantity of segments is superior to sequence search fetching method ,and error affinity probabili‐ty function has good stabilization ,convergence and sensitivity .%核电厂数字化人机界面功能块中的构件数量给操纵员带来了极大负荷并影响人误事件的发生。本文对功能块中的参数数量建立了一完整的优化流程图，对流程图中的几个关键部分进行详细研究：对因子数量采用动态模糊分段法产生模糊数量段；在模糊数量段因子的搜索中，建立了模糊数量段的取中查找提取方法，大幅提高了搜索性能；对人机界面参数量设计了失误亲和率函数。试验结果表明：模糊数量段的取中查找提取方法明显优于顺序查找提取方法，失误亲和率函数具有较好的稳定性、收敛性及灵敏度。
