Research On Information Integration In Collaborative Logistics

Collaborative Logistics is defined as that logistics enterprises share information through internet and create collaborative environment to optimize internal resources distribution of enterprises, through which can support collaborative logistics’ business and make better performance and more profits. Information collaboration is the critical part and impelling force of collaborative logistics; thus, it is necessary to design an information integration platform for information interchange among logistics enterprises. Given that enterprises in collaborative logistics had built their own information system separately, the new creation of the platform can be developed in low expense and rapid way if it makes full use of the existing systems. Therefore, the study of information integration of existing systems in collaborative logistics is of great significance, which can help enterprises regulate collaborative logistics business and also improve efficiency.The thesis analyzed the management demands in collaborative logistics sufficiently and designed a model for information integration in it. The model divides the methods of information interchange into two ways:one is asynchronous information interchange, through which the information is interchanged through periodical data synchronization; the other is synchronous information interchange, through which the information is shared by the integration of information systems. The periodical data synchronization contains the use of trigger and log table to detect and record the changing data, and synchronizing module for heterogeneous databases based on Web Services. Besides, through the study of Service Oriented Architecture (SOA) and Web Services, the thesis designed the service oriented information systems integrating model, which features clear hierarchy making the integration being effective in both data level and business level. The model is based on SOA and Web Services, it eliminates the obstacles of heterogeneous platform and running environment, and makes reuse of the existing systems. Specifically, the model encapsulates the existing business functions as services, and integrates the services by BPEL to implement the collaboration of business functions from different systems, which serves the demands of collaborative logistics. At the end of the thesis, the implementation of the information integration model on a real project demonstrates its effectiveness. The integration solution in the thesis provided references for further study of collaborative logistics. Firstly, it solved the integration problem of heterogeneous systems. Secondly, it realized the business collaboration on different enterprises through data integration and services integration. Finally, it can support the business regulation and improve the efficiency of collaboration. To sum up, the study can impel the development of collaborative logistics and is of practical significance.
