摘要
多准则群体决策环境下,决策个体间存在复杂交互关系,由经验阈值引导的共识过程难以规避非合作行为对共识的扰动,导致群体决策结果的一致性与稳健性较差.本文聚焦于群体共识实现过程中交互网络结构,共识驱动要素和偏好交互模型等三个核心内容,提出了基于BA-BSO交互机制的自适应群体共识模型.鉴于交互关系分布的不平衡性,本文设计了BA无标度交互网络模型,实现对非合作者的动态识别及其交互关系的自适应管理.其次,结合个体贴近度和共识成本设计了满足超模博弈条件的个体交互效用,以引导个体偏好的收敛与群体共识的自发涌现.在偏好交互过程中,本文基于BSO优化算法和“多数原则”设计了偏好交互模型以及最优方案选择规则,既反映了个体与相近观点交互的倾向,又规避了非合作者观点的过度影响,改善了群体决策结果的一致性与稳健性.最后,算例分析与对比分析说明了本文方法的有效性与优越性.
The group consensus reaching process induced by the empirical threshold can be significantly influenced by non-cooperative behavior, reducing the consistency and robustness of decision results. Concentrating on the three core contents of the consensus reaching process:Interaction network structure, consensus driving element, and preference interaction model, we propose the adaptive group consensus model based on the BA-BSO interaction mechanism. Considering the imbalance of interaction relations, the BA free scale interaction network is developed to control the interaction opportunities of non-cooperators adaptively and dynamically. Then,the individual interaction utility function, satisfying supermodular game condition, is designed to induce the spontaneous emergence of group consensus, which consists of proximity degree and consensus cost. Through the interaction process, we propose the BSO algorithm-based preference interaction model to reflect the individual interaction preference and avoid the excessive influence of non-cooperators. Moreover, the optimal alternative selecting rule is proposed based on the “Majority Principle”, enhancing the consistency of group decision results. Finally, the effectiveness and efficiency of the proposed consensus model are illustrated by numerical example analysis and comparative analysis part.
