It's the requirement to research data replication strategies for improving the reliability and efficiency of complex network. We use noncooperative game theory to analyze the replica placement problem in the paper, and the model of replica placement in large-scale distributed network is proposed. Then we prove the existence of pure strategy Nash equilibrium in the model, and propose the replica placement...
In this paper, by using the theories and methods of ecology and ordinary differential equation, an impulsively controlled one-prey two-predator system is established. And we consider the globally asymptotically stable of prey and one predator eradication periodic solution. Furthermore, numerical simulations are also illustrated which agree well with our theoretical analysis, All these results may...
Based on the analysis of evaluation theory of English textbook, in view of the large number of checklist items and the difficulty in quantitative analysis of evaluation criteria, fuzzy set theory is introduced into English textbook evaluation in this paper. The proposed fuzzy analytic hierarchy process (AHP) uses fuzzy pair wise comparison judgments rather than exact numerical values of the comparison...
