在DHGF算法中,不同白化权函数的选择会产生不同的评估结果.专家在确定函数类型上具有主观性,针对结果会受到主观影响的问题,基于中心点三角白化权函数,构造动态梯形白化权函数,增强结果客观性,推广了经典DHGF算法.该方法给出的评估值是区间形式,有利于决策者清楚目标所在风险等级的概率,提高评价准确性.最后结合实例表明该方法的合理性和有效性.
The selection of different whiten weight functions produces different evaluation results in the DHGF algorithm. Experts have subjectivity in determining the function type. For the problem that the result will be subjectively affected
the dynamic trapezoid whiten weight function is constructed in this paper based on the center point triangular whiten weight function
which is used to enhance the objectivity of the result
and promote the classical DHGF algorithm. The evaluation value given by this method is in the form of intervals
which is beneficial for the decision makers to know the probability of the risk level at which the target is located and improve the accuracy of evaluation. Finally
an instance is given to verify the effectiveness and rationality of the method.
