Modeling and Simulation of Synchronous Threshold in Vent Collective Behavior

الملخص EN

With the strengthening of the social contradiction, the outbreak of vent collective behavior tends to be frequent.

The essence of vent collective behavior is emergence of synchronization.

In order to explore the threshold of consensus synchronization in vent collective behavior, a mathematic model and a corresponding simulation model based on multi-agent are proposed.

The results of analysis by mean field theory and simulation experiments show the following.

(1) There is a threshold Kc for consensus synchronization in global-coupling and homogeneous group, and when the system parameter K is greater than Kc, consensus synchronization emerge.

Otherwise the system cannot achieve synchronization.

The conclusion is verified by further study of multiagent simulation.

(2) Compared with the global-coupling situation, the process of synchronization is delayed in local-coupling and homogeneous group.

(3) For local-coupling and heterogeneous group, consensus dissemination can achieve synchronization only when the effects of the parameters meet the threshold requirements of consensus synchronization.
