The Study Of Coevolution Of Epidemic Spreading And Message Diffusion Processes On Multiplex Networks

Since the end of the last century,with the improvement of computer technology and the gradual development of the Internet,the study of complex networks has received tremendous advancement.Compared with traditional disciplines,complex network is an emerging field,which has attracted scholars from different disciplines to work on it to decently understand mechanisms of various complex systems prevalent in reality.Through appropriate methods including data analysis,model generation,mathematical theory development,and numerical simulations,various topics have been explored in which problems in epidemic spreading as well as information diffusion have become a central research object.In the real world,the spreading of epidemics is complicated and often influenced by individual consciousness.Conscious individuals who get epidemic information will take a series of intervention and prevention measures to reduce their risk of being infected by epidemics.At the same time,in real life,the spreading of an epidemic is accompanied by the spreading of other infectious diseases,so it is necessary to study the spreading process of coexistence of multiple epidemics.Inspired by various influences on the spreading process of epidemics,this paper proposes a multiplex network model,which studies the co-evolution of two competitive epidemics and the information dissemination process of transmitting prevention awareness by using microscopic Markov chain approach and Monte Carlo numerical simulation.The former represents the biological inhibition effect and the latter represents the social inhibition effect.Our study shows that when these two factors work at the same time,their combined impact on the spreading of an epidemic is not necessarily inhibiting,but may even promote the spreading of an epidemic.In this paper,this phenomenon is analyzed in detail,and the internal mechanism of this phenomenon is explained.We hope that our study can provide useful insights in formulating the controlling strategies of epidemic spreading under the complicated situations where multiples infectious diseases spread simultaneously.This paper first introduces the background and basic concept of the complex network,and then reviews the epidemic spreading dynamics research history,then introduces the research progress of epidemic and information coupling transmission dynamics and the spreading of the epidemic of multiple Shared on the network evolution model,and shows the epidemic spreading on the network and information diffusion evolution mechanism of the common research results,At last,the thesis makes a general summary of the research content.
