基于 OODA 循环的应急物资协作网络关键主体识别

In order to identify the key subjects in the material support collaboration system and improve the efficiency of emergency organization, on the basis of considering the participation of multiple social subjects, the OODA cycle theory was used to construct the emergency material support collaboration framework. According to the contribution of the subject in the formation of the collaboration ring and the performance of the collaboration, the identific ation method of the key subject was established. The phased development of the novel coronavirus pneumonia epidemic was taken as an empirical case to verify the effectiveness of the method. The results show that the three key subjects in the case collaborative network are the information subject S₃, the information subject S₅ and the execution subject I₁₈. More than 70% of the collaborstion ring structures are complex. The amount of information subjects is the least, but the average collaboration efficiency is the highest. The executive subjects have an important role in the expansion of the collaboration ring, and the decision-making subject has obvious advantages in the collaboration efficiency. The efficiency distribution of the three types of collaborative relationships in the task delivery process is balanced, among the three types of collaborative relationships in the task collaboration process, the number of execution relationships is the largest and the efficiency is the highest.
