The network of Guangxi Development and Planning Commission is a node of the portrait network of the national planning system.

Multinational Companies R&D investment in China s electronics and information industry affects the advantages of the longitudinal inter-firm network by changing China s companies gradation in the network.

Based on the theory of the value network, this paper proposes constructing the vertical cooperative innovation network that is taking consumer-value as centre, taking industrial chain as mainline, and taking product innovation as object.

The basic idea is that three network manipulators, the passengers, the urban public traffic company and the government traffic management depart.

To solve the path optimization problem in undirected network,genetic algorithm is presented and variable-length chromosomes(routing strings)and their genes(nodes) are used for encoding the problem.

In this paper,an applied algorithm is given by changing the description of the maximum flow problem in undirected network.

Based on non-uniform swarm,a dynamic model in directed networks was constructed.

The deformed Floyd algorithm of the shortest path between the two nodes in the directed networks is presented and the complexity of time shares the same rank with Floyd algorithm,but it reveals an object image and provides an easy way to programme.

So far, few of researches have focused on the theory and application of directed networks, and most of them treated directed networks as a na?ve extension of undirected networks .
