Analysis Of The Significance Of Nodes In Logistic Support Networks Based On Tasks

In recent years, the study of complex networks has set off an upsurge all over the world. Researchers of different fields, such as physics, biology, mathematics and computer, all turn to complex networks. Logistic support networks have always been the center of the research of complex networks. With the evolution of modern battle styles, especially the local warfare after 90's of last century, logistic support networks become more and more important, and the ability and quality of logistic support become key factors that decide the success of modern battles. At the same time, the logistic support networks are the focus of attack and defense. Analysis of the significance of nodes in logistic support networks is of great theoretical and practical importance. The main work and contributions of this dissertation are as follows.1 ) A new aparameter of analysis of the significance nodes is proposed. Based on the natural connectivity, a new parameter of the significance of network node---the importance of network node structure, is proposed. Both the solution and computer simulation algorithm of the parameter is given out. Through compare and analysis of different types of network, the rationality and correctness of the parameter is proved.2 ) Model of logistic support networks and description of task. After analyzing the characters of logistic support networks, a model for it is built. A mathematical expression for network task is also given out. And all the network tasks are classified respectively.3 ) A new concept of network nodes importance analysis is proposed. So far, network nodes importance analysis is carried out based on the analysis of network structure, which does not take network tasks into consideration. While, a great deal tasks exist in real networks. Thus, an task-based logistic support network nodes importance concept is built. To solve the problem, a delamination of distilling sub-network of task method is constructed, by which the importance of logistic support network nodes can be analyzed.4 ) A software of logistic support network nodes importance analysis system is implemented. Software of logistic support network nodes importance analysis system is implemented, which provide a platform to analyze network nodes. On the platform, a logistic support networks can be built and the network tasks can be edited. Through the software integrated degree of network nodes, network node constringency method and the algorithm proposed in the dissertation, which ensures the analysis of importance of different network nodes.
