After decades of construction, China Railway information system has achieved a great development. Information technology is playing an important role in every areas of the railway system. We should, however, notice the disadvantages existing in current railway information system. The biggest problem is the interconnection and interoperation between systems. Service-Oriented Architecture (SOA) is now an ideal solution to integration of heterogeneous systems and applications. SOA can use the legacy system, gain cross-platform integration and enhance the reuse of the application components. Thus the cost of development could be reduced and the deployment could be accelerated. The IT system could be flexible to the constant changing of the business process in the enterprises. The main purpose of this thesis is to research the ways of finding the proper services for China Railway information system and provide a modeling method to help the implementation of SOA in China Railway information system.This thesis first introduces the basic concepts of SOA and analyses its principles. Then a modeling method is proposed which includes six steps: that is domain decomposition, functional analysis, service goal analysis, sub-system analysis, method operations merging and services design. At the step of services design, a clustering method is introduced which could help designing the services better and more objectively. Based on the research above, this thesis studies the current situation of China Railway information system and applies the modeling method to the freight transportation system. Finally, a simple example is built using Web Services according to the modeling results. This thesis could act as guidance on the implementation of SOA in China Railway information system.
