项目摘要

Generally, manufacturing companies forms virtual companies with other manufacturing companies by information alliances instead of integration with others, to take in autonomous necessary technologies and to enhance competitive power. In addition, the companies forms the supply chain covering all business processes, such as procurement of raw materials, manufacturing, processing, storage, transportation and distribution and transform their manufacturing activities from "manufacturer-led push-out operation" to "customer-driven pull-out operation" The transformation is assisted by enterprise resources planning (ERP) package systems aiming to the logistics - one of the major activity areas of enterprise. The ERP consists of standard business models, has global standard functions, processes in real-time and makes it easy to form supply-chain. But the production control of ERP is based on material requirements planning activity and is not directly connected the plant control system (PCS). The ERP is directly bridged to the PCS by manufacturing execution system (MES). The MES makes the field-based PCS act in concert with the office-based ERP, i.e.-forms the plant-centric supply-chain. In general, a business information system composed of three layers, such as presentation, business logic and related database. Similarly, it is considered that operation information system composed of four layers, such as presentation, operation logic, real-time database and process control. Therefore, it is considered that the ERP-MES integration system has a hybrid structure of six layers, i.e. presentation for coexistent office user and plant operator, business logic, relational database, operation logic, real-time database, process control.

制造企业一般通过信息联盟而不是通过与其他制造企业的整合来组建虚拟企业，以吸收自主的必要技术，增强竞争力。此外，公司还形成了涵盖原材料采购、制造、加工、仓储、运输和配送，并将其制造活动从“制造商主导的推出式操作”转变为“客户驱动的拉出式操作”。企业的主要活动领域之一。ERP由标准的业务模型组成，具有全球标准功能，实时处理，易于形成供应链。但ERP的生产控制是基于物料需求计划活动的，并不直接与工厂控制系统（PCS）相连。ERP通过制造执行系统（MES）直接连接到PCS。MES使外地PCS与办公室ERP协同工作，即：形成以植物为中心的供应链。一般来说，一个业务信息系统由三层组成，即表示层、业务逻辑层和相关数据库层。同样，认为操作信息系统由表示层、操作逻辑层、实时数据库层和过程控制层组成。因此，认为ERP-MES集成系统具有六层混合结构，即办公用户和工厂操作员共存的表示层、业务逻辑层、关系数据库层、业务逻辑层、实时数据库层、过程控制层。
