Study On Simulation Of China's Dairy Industry Crisis Spread Based On Opinion Dynamic

Industry crisis is the emerging research object of crisis management.The financial industry,energy industry,and the dairy industry are all part of the manufacturing industry crisis hit hard.Generally,industry crisis is not formed immediately,but from small to large,from part to whole,gradually forms,which involves the spread of the industry crisis problem.The spread of the industry crisis has caused the industry and the wide attention of scholars.Dairy industry is a typical crisis spread industry.In recent years,the dairy industry crisis events have occurred many times in industry,brought huge losses to the whole industry.In this background,this paper combines with opinion dynamics theory and multi-agent simulation tools,to simulates of the dairy industry crisis spread,masters the regular pattern of the dairy industry crisis spread,finds the key factors,which influence the industry crisis spread,and provides scientific evidence for scientific and reasonable strategies to suppress the spread of industry crisis for enterprises and government departments.This paper first introduces the development of the dairy products at present situation and industry characteristics from the general situation of the dairy industry,then analyzes the connotation of the dairy industry crisis,and expounds the dairy industry crisis from three aspects of the definition,source of crisis,the form of crisis,and analyzes the connotation of the dairy industry crisis spread from four dimensions such as crisis spread factors,main body,the model of spread,the channel of spread.This laiesa foundation for the modeling and simulation of the dairy industry crisis spread.Then it introduces the opinion dynamic model,and demonstrates the rationality of the combination of dairy industry crisis spread and opinion dynamic model.And elaborates the idea of the dairy industry cisis spread model based on opinion dynamic,analysing the state transition equation and putting forward the crisis spread algorithm process based on the detailed attributes analysis of the subjects of the dairy industry crisis spread.Finally,it conducts experiments about dairy industry crisis simulation using Netlogo,and analyzes the different situation,the influence of different parameters on the dairy industry crisis spread,and it gives crisis control strategies from the point of enterprises and government according to the previous analysis and the simulation results.The thesis research results will help to grasp the spead regularity of the dairy industry crisis,and find out the key factors of crisis spread,and provide evidences to develop the strategies to suppress and eliminate the dairy industry crisis spread.
