Multiple enterprises are usually involved in supply chain network, while almost each enterprise has its own information systems and databases (enterprise legacy systems). There are large quantities of information and data intersecting or even repeating with each other, which calls for system integration. Meanwhile in the cooperative process of supply chain, the whole product line or product family is involved in the enterprise systems, including PDM, ERP, SCM, and CRM et al, which also need interaction and integration. Although many data integration methods and corresponding tools have been applied to the business cooperation in the environment of supply chain, however the interoperability of enterprise information systems is becoming more and more complex, because of the restriction from lots of factors, such as the complexity of enterprise application systems and the diversity of heterogeneous data sources, especially the new application demands of enterprises. In this dissertation, the interoperability method of networked enterprise information systems in the environment of supply chain is studied, from the point of theoretical modeling and application.
