Abstract: The simplification of network analyses model is achieved, the process is simplified from the affusion channels→crunodes→effusion channels to crunodes→effusion channels, based on the conception of network-crunodes buffer pool. The complicated stream-quantity control model is built up through distribution of the amount of water; and the transformation from static model to dynamic model is achieved by building up increment mathematical model and virtual stream-pervasion; and joints for complicated affusion model are provided by founding distribution strategies.
