摘要
针对复杂装备技术状态评估权重确定过程中存在的专家犹豫和权重确定动态性不足的问题,结合区间值犹豫模糊熵、毕达哥拉斯模糊集和Hamacher算子,提出Hamacher区间模糊算法。综合各专家对各元素重要性的打分,构建区间值犹豫模糊集,改进区间值犹豫模糊熵,并对模糊集中各犹豫模糊元运算得到区间值犹豫模糊熵矩阵;令区间值犹豫模糊熵为隶属度,打分区间差值为犹豫度,得到毕达哥拉斯模糊集,运用Hamacher区间模糊算法计算得到各元素重要度得分函数,将得分函数归一化得到最终元素权重。算例结果表明,该验证方法对技术状态评估具有适用性。
In order to solve the problems of experts' hesitation and the lack of dynamics in the process of determining the weights of technical condition assessment for complex equipment,a Hamacher interval fuzzy algorithm is proposed by combining the interval-valued hesitation fuzzy entropy,Pythagorean fuzzy set and Hamacher operator.The interval-valued hesitation fuzzy set is constructed by integrating the scores of each expert on the importance of each element,the interval-valued hesitation fuzzy entropy is improved,and the interval-value hesitation fuzzy entropy matrix is obtained by operating each hesitation fuzzy element in the fuzzy set;The Pythagorean fuzzy set is obtained by t aking the interval value hesitation fuzzy entropy as the membership degree and the scoring interval difference as the hesitation degree,and the Hamacher interval fuzzy algorithm is used to calculate the score function of each element importance,and the s core function is normalized to obtain the final element weight.The results of the example show that the verification method is applicable to the state of technology assessment.
