In view of the new requirement of railway information service, such as information sharing, collaboration, etc. which occurred during the development of railway information construction, Grid computing was introduced into the field of railway information service, which analyzed the development trend of railway information service based on grid, made a research on the application of the grid computing in the field of railway, constructed railway application framework based on grid, proposed grid-based railway IT system and provided a theoretical basis and reference for the grid application in railway information service.

Industry security system is a complex giant system, madding up of multiple subsystems, and presenting features of hierarchy and complexity. Based on the industrial security characteristics and requirements, using the theory and method of system science, this paper analyzes the related issues of industry security. And the research mainly regards to industry security system components and the correlation between each element. And the model of correlation for industry security system elements is put forward innovatively, which has certain practical significance.

In order to meet the demand for railway information service, Discussed the grid connotation and the theory of grid architecture, used Service-Oriented idea, the architecture of railway information service was proposed in the grid environment, the level of architecture was determined, Meanwhile composition, functions and the hierarchical relationship of the architecture were discussed in detail, the research focus on providing the top guidance for the construction of the railway information grid system.

The domain of railway is the most promising field when IOT applies in practice. By means of expounding on the connotation of railway information technology, carrying out research on the components of railway information technology and classifying it into categories, this paper constructs railway information technology system based on Internet of Things (IOT). It buttresses further application of the IOT in railway field.

When IOT applies in practice, the domain of railway is the most promising field. Through elaborating the essence of railway information sharing, combining Internet of Things (IOT) technology characteristics in railway transport system, this paper analyzed the integrated process. It designs railway information systemintegration scheme based on IOT in term of realizing railway informationsharing, so as to provide the theoretical and technical support for therealization of railway business and system information sharing and collaborative.

With the Internet development, Internet of Things(IOT) technology is widely used in the production. Combined with China'srailway system demand status quo for integration and sharing of resources andanalysis IOT key technology and operating principle, this paper proposes to constructthe railway information integration and sharing mode in IOT environment. Itincludes railway network system and railway information resources integrationand sharing platform based on IOT.

Considering the concept of service chain and the environment changes of supply chain logistics industry, the supply chain logistics based on service chain was proposed,on this basis of character, analysed the building of its service architecture and service information platform were deeply researched.
