摘要
考虑决策者在时间紧急及信息不完备的情况下给出评估值时可能会出现犹豫不决的情况,提出基于犹豫模糊集的网络舆情突发事件应急群决策法.首先,通过犹豫模糊信息熵及交叉熵建立各评价指标的权重确定模型;其次,利用犹豫模糊加权平均算子及得分函数计算各突发事件评价指标的犹豫模糊评估值得分;然后结合各评价指标的权重值及评估值得分,计算出各网络舆情突发事件综合危害性得分,进而辅助应急部门确定各网络舆情突发事件的处置顺序;最后通过案例分析证明了方法的有效性.
Considering that decision maker may hesitate to give the assessed value in the scenario of time urgency and incomplete information,the emergency group decision making method of internet public opinion outbreak based on hesitant fuzzy set is proposed.Firstly,the weight determination model of each evaluation index is established by hesitant fuzzy information entropy and cross entropy.Secondly,the HFWA and score function are used to calculate the evaluation score of each evaluation index.Then,using the weight value and evaluation score of each index to calculate comprehensive harmfulness score of internet public opinion emergency to assist emergency departments to determine the disposal order.Finally,the effectiveness of the proposed method is proved by a case study.
