Research On ERP Key Technology And Implementation For Mechanical Engineering Industry

Under the background of manufacturing industry enterprise informationlization andenterprise operate environment continuously changing, facing to the function request ofthe agile manufacturing, aiming to dynamic business process, this thesis studies thereconfigurable agile ERP system. The thesis primarily studied several key technologies,such as enable technology, system process modeling, system backbone, enterpriseapplication integration, system implement methodology etc. Finally the research theorywas applied to a SME's information engineering. After researched the basic concept of enterprise model, compared several referencemodels such as CIM-OSA, GRAI, this thesis presented Model Hierarchical Architecture(MHA). The MHA includes three parts: industry reference model, modeling method andbuilding process. The MHA established the theories foundation for agile ERP system. Based on above technologies and theories, the author optimized the business processwhich is defined by Petri net based on rule of management knowledge. This thesis putforward dynamic reconfigurable ERP system framework, studied several keytechnologies such as object hiberarchy, operation mechanism, reconfigurable strategy,component library, dynamic modeling, etc. In addition, this thesis presented basic objectinformation and primary function flow chart. In order to satisfy the need of enterprise global informationlization, this studydiscussed integration of PDM and 3C, integration of MES and ERP based on dataflow,integration of PDM and ERP based on product structure, integration of ERP and electriccommerce. The aim was to realize the integration of information, function and processwithin the whole product lifetime that includes designing, manufacturing and distribution. According to author's experience, this thesis finally expatiated a total solution abouta SME information system project, which involved CAD and PDM in design field, CAMand CAPP in manufacturing field, CRM in distribution field. The author mainlyintroduced ERP implement process, which including BPR, implement measuring andbusiness process continuous improving, etc.
