首先建立突发事件群体决策的Q学习模型,给出决策者的Q值表,以及智能体行动规则;然后基于Netlogo软件平台,编程实现突发事件群体决策的元胞自动机仿真系统;再对决策群体应激能力相同和不同两种情况研究其群体决策,模拟其演化过程。最后,分析这两种情况的仿真结果,并得出结论:对于一个应急决策团队而言,在决策者风险偏好不同的情况下,决策者应激能力差异越大,其群体决策集结的效果越差。
Firstly, the Q learning model of emergency group decision-making is established, the Q-value table of decision makers and the action rules of agent are given. Then, based on the Netlogo software platform, a cellular automata simulation system for emergency population decision-making is programmed. The decision-making groups have the same and different stress ability to study their group decision-making and simulate their evolution process. Finally, the simulation results of these two cases are analyzed and the conclusion is reached: for an emergency decision-making team, the greater the difference in decision-makers’ stress ability under the different risk preferences of decision-makers, the more the effect of their group decision- difference.
