The challenging problem is how to store and search data efficiently when applying P2P technology in e-commerce. In order to solve this problem, we propose a P2P e-commerce model based on interest community, which manages each user's data by use of interest community. Users with similar interests form an interest community. Interest communities will reorganize as any user's interest has changed. Simulation...
In view of the characteristics of complex system, such as decomposability, complex internal connection, the paper researches multi-layer state space model, and further discusses a same level system mode with graph theory. Finally, it puts forward a multi-layer state space modeling way of complex system based on graph theory, and uses the way to complete a renewable energy statistical analysis model...
The complex network model is the research foundation of complex network, so it is important to evaluate and select model objectively .There is no effective evaluation way up to now. An evaluating method using cloud model is proposed to decrease randomness and fuzziness existing in conventional evaluation. The results of simulating experiments prove that such uncertainty is solved well.
