摘要:

针对大群体应急决策中信息不完备、共识达成困难等问题,本文构建应急决策群智知识融合模型融合广泛群体的智慧为应急决策服务,并在此基础上,设计大群体应急决策共识模型提高群体共识水平。首先,挖掘社交媒体中的公众群智知识,得到公众关注主题及权重,将其作为决策属性信息纳入到应急决策过程中;其次,基于专家的信任关系和偏好关系定义内聚系数和耦合系数,确定聚集融合权重,利用群智知识融合模型融合专家智慧和公众智慧,得到综合的群智知识结果;然后,根据应急决策问题特征确定共识反馈调整参数,基于群智知识融合的结果进行共识测度,分析聚集的内聚特征和耦合特征,识别聚集类型,并提出偏好调整建议,通过共识反馈调整得到高一致性的大群体决策结果;最后,将本文提出的模型方法应用到传染病公共卫生安全事件防控案例中,与其他文献方法进行对比分析,验证本文方法的合理性和优越性。

Abstract:

Aiming at the difficulty of incomplete information and reaching consensus in large-group emergency decision-making,a group wisdom fusion modelintegrating the wisdom of a wide range of groups for emergency decision making are constructed. On this basis, a consensus model for large group emergency decision making was designed to improve the level of group consensus.Firstly, the public group wisdom is mined in social media to obtain public topics and weights, which are used as decision-making attribute information to participate in the emergency decision-making process.Secondly, cohesion coefficient and coupling coefficient are defined based on trust relationship and preference relationshipamong experts, and cluster weights were determined. The group wisdom fusion model is applied to integrate expert wisdom and public wisdom, and hte comprehensive group wisdom result is obtained.Then, consensus feedback adjustment parameters are determined according to the characteristics of emergency decision-making problems, and consensus measurement based on the results of group wisdom fusion is conducted. By analyzing the cohesion characteristics and coupling characteristics of cluster, the type of cluster is identified and the preference adjustment suggestions are proposed to achieve a high consistency large group decision result. As a result, the rationality and superiority of the model methodproposed in this paper are verified by applying it to the case of “preventing and controlling of public health safety incident related to infectious diseases”.
