In this paper, the flux of the information in the process of the manufacturing is analyzed, the new method, which is named the information chain, is introduced to get touch with each system.

The paper first researches into the SCM models based on linear,netty and compostive information chain,then concludes that the SCM model based on compositive information chain is better,and finally analyzes the operation of this model in detail.

Regard Petri network as tools,the model of ground antiaircraft information chain is structured and optimized.

To gain continuous development of China’s textile and garment enterprises, market, design and so on, the information link must be built, which goes through the whole course of enterprise operation and holds the life line of the development of textile and garment industry.

The (TADIL) A is a new kind of tactical digital information link, used in the naval vessels equipped NTDS AEGIS for information exchanging or data exchanging between naval vessels and early-warning airplane.

In order to use unlabeled data to help classification and get higher accuracy,computed edge weights of the graph through combining weighting schemes and link information of Web pages.
