[Abstract]:With the availability and analysis of real complex system data, people have a deeper understanding of the characteristics of the networked structure of the system. In particular, the analysis of the relationship between structural characteristics and system behavior mechanisms has attracted more and more attention of researchers. In this paper, based on a review of the current research situation of structural characteristics of complex network theory systems, From the angle of network modeling and analysis, the intrinsic characteristics of the object are deeply mined, and the influence of network structure on the dynamic process mechanism on the network is further studied. On this main line, the main contents of this paper are as follows:. 1) in the aspect of complex network modeling and object structure characteristic analysis, complex task-resource network modeling is carried out for refining system of process industry. The network structure is analyzed in combination with the production scheme and the device function. The simplified model established according to the production rules can verify the reliability of the structural features and illustrate the close relationship between the structural features and the production process. The network analysis method can provide the available information for the overall analysis of the system. 2) when the data scale and complexity increase, the network analysis method can further combine the object attribute and the structure characteristic, deeply excavate the internal information of the data, use the online transaction data of a website, construct the city transaction relation network. This paper makes full use of the global connection relationship of nodes in the network, through backbone analysis method and fund flow test, deeply excavates the information contained in the structural characteristics of objects. From the perspective of the network, this paper makes a comprehensive analysis of the level of online transactions in various parts of China. Visualization technology is used to display the results, which reflects the unique perspective of structural feature analysis in data mining. 3) in the research of the relationship between the network structure characteristics and the dynamic mechanism of the system, firstly, the influence of different static network structure characteristics on the dynamic process on the network is discussed, and the analysis of the logistics process in the supply chain network shows that, The common cluster structure in the real system will obviously improve the effective utilization of the system resources and help the supply chain network to obtain higher logistics efficiency. This analysis clarifies the influence of the structural characteristics on the dynamic mechanism of the system. A quantitative comparison is made in a specific object. In this paper, we discuss the influence of dynamic network structure on the dynamic process mechanism of the network. In the dynamic network based on the active driving model, we use the population infection model to simulate the transmission process of message, disease and so on. The global diffusion threshold of the transmission process is analytically analyzed by combining the two specific transmission mechanisms of infection and diffusion. The simulation results further verify the specific influence of the structural dynamic characteristics on the propagation process. In view of the network of structure changing with time, this paper discusses the control effect of the control method of the structure information on the dynamic process on the network. Combining with the dynamic structure information of the active driving model, the random and objective are put forward. Through theoretical derivation and simulation experiments, the control effect of the three strategies on the transmission process is compared. The results show that the three strategies can inhibit the transmission process to a certain extent. The control effect of target immune strategy is the best, and that of random strategy is the weakest. Neighbor immune strategy can overcome the lack of global information and provide better control effect. It is a control method suitable for the propagation process in dynamic network. Finally, on the basis of summing up the full text, several problems that need to be studied deeply in the analysis and application of the structure characteristics of complex network theory are put forward.
