related to an enumerator’s religious adherence. We find tha...
针对现有的直觉模糊熵的公理化定义和构造公式未能全面体现直觉模糊集模糊性的缺陷进行分析, 提出一种改进的直觉模糊熵的公理化定义, 据此构造一个新的直觉模糊熵的计算公式, 并将该公式与现有直觉模糊熵公式进行比较. 算例分析表明, 所提出的熵公式能够更充分地反映直觉模糊集的不确定性和未知性程度.
针对多维隐式结构可靠性问题,应用降维可视化技术进行可靠性灵敏度分析。基于iHLRF法求解设计点,根据模型计算精度确定有限差分步长。用一条直线将平面分为安全域和失效域两部分,通过计算直线初始位置附近数据点对应的响应量,来调整并确定直线的最终位置,根据直线上方数据点提供的信息计算可靠性灵敏度。提出的可靠性灵敏度分析方法的准确性不受维度以及非线性的影响,且效率较高。最后计算了两个结构系统的可靠度及各个变...
