Research And Application Of Middle Integration Platform In Product Design And Manufacturing Process

As enterprise's informatization process stepping further, more attention has been paid to the problem of sharing information between various application systems. Most of enterprise application systems are functionally strong, but their functions have not been adapted to ever-developing business needs. However, application integration covering data integration, functionality integration and workflow becomes more and more urgent. Traditional end-to-end integration mode is not qualified for fulfilling these new requirements since it has many limitations, such as functionality singularity, non-framework infrastructure and weak expansibility. Middle integration platform (MIP) technique makes up above defects and solves different enterprise integration problems.By analyzing the development course and general state of MIP including the related technology and products at home and abroad, this thesis encloses some primary problems that MIP faces currently. After analyzing and describing these problems, this thesis proposes a viewpoint of overall integration needs of MIP in product design and manufacturing process. Under the lead of these needs, this thesis researches into integration layer, data structure, system architecture and function model of different application systems, and then presents a solution of MIP based on XML data bus. MIP is based on three-layer framework. It makes use of some primary technology including data conversion between relational schema and XML schema, embedded adapter, data base access to exchange integration data among CAX, PDM and ERP. MIP based on the modularized design possesses better maintainability and expansibility。In order to verify the research described above,the author collects integration needs from many enterprises in manufacturing, and analyzes integration data, data structure, system architecture and function model of different application systems in product design and manufacturing process. Then the author uses some primary technology to develop MIT-middle integration platform system (MIT-MIP) based on XML data bus among CAX, PDM and ERP. At last, the author uses AutoCAD/MITPDM data integration and UG/MITPDM data integration to describe data integration process, which verifies the feasibility of the systematic framework and realization tactics presented before.
