The Simulation Research On Group Decision Making

With the further development of social science,the emergence of some macroscopic phenomena in the complex network gets more and more attention from scholars.In which one of the most concerned phenomenon is the evolution of opinions as well as the emergence mechanism in network.And the usual research method to study the evolution of group opinions is to consider it by modeling,moreover,a number of significant results could be observed in previous studies.In this article,we proposed some model improvements which are more realistic on the basis of the existing opinion models,and the relevant model is improved so to performed the numerical simulation.In the simulation,we introduced a variety of network structure and obtained the influence of some important parameters by changing them in the process and comparing the result.Furthermore,we observed the effect of improved factor in the convergence process.We also made some comments and suggestions for the actual phenomenon besides.Research in this article would contribute to a better understanding of the opinion interactions and the emergence phenomenon that performed by individuals in network,as well as the influence of individual features on the opinion dynamic.The result of this article also could provide some effective reference to the studies of network individual behavior and the trend forecasting of public opinions.
