Abstract


We come into contact with a lot of natural and artificial network is a complex network , for example : communication networks , computer networks , transportation networks , social networks and so on . These networks are closely related with our daily life , so we need to study and understand the nature of the complex network , including the topology of the network , operating mechanism , dynamic behavior and synchronization capabilities , in order to better design and manage these actual complexity network for human Services . Complexity of network reliability study is essential for understanding the structure and behavior of the network , and the complexity of network reliability evaluation is an important part of complex network reliability study , is the basis of a complex network reliability evaluation . In this thesis from the following aspects : ( 1) Summary describes the complex network research background , current status and research ; (2) a complex network reliability evaluation index system is established on the basis of previous results , including invulnerability , survivability , effectiveness and reliability of the synchronization of the four aspects . (3) preparation of the MATLAB numerical calculation tool for complex network reliability evaluation software . Include: to generate a random network and scale-free networks , random attacks on the network and intelligent attack , calculate the average shortest path than average clustering coefficient than the coupling matrix eigenvalue reflects the measure of the reliability of these three . Reliability evaluation laid the foundation for the next step . ( 4 ) the use of the reliability index data on the reliability of the network model to analyze and draw conclusions. (5) This paper points out the inadequacies and further research directions .
