网络联盟企业中基于Web的制造执行系统

摘要

网络联盟企业是按照分散网络化制造哲理组建的企业。制造执行系统在生产信息管理系统与设备控制系统之间构筑一座桥梁，连接企业上层管理与工作地之间过去一直被忽略但急需解决的信息断层。介绍了制造执行系统的功能，制造执行系统与管理系统、控制系统的关系和信息流。阐述了在网络联盟企业中基于Web的制造执行系统的体系结构。%The extended enterprise is formed according to the concept of dispersed networked manufacturing. The manufacturing execution systems bridge the gap between the batch oriented business systems and the real－ time oriented control systems on the manufacturing plant floor. This paper introduces the functions of the manufacturing execution system, the relationship and information flow among MES, production management system and device control system. It also introduces the architecture of web－ based manufacturing execution system in the extended enterprise.
