摘　　要： ERP系统面向客户从整个企业的层面制定的生产计划需要根据工厂实际状况进行执行 ,但由于ERP本身的限制及工厂层的动态变化特性和生产过程中的大量不确定性使得管理层的计划常常和工厂层的实际情况相脱节 .制造执行系统 (MES)就是为了解决这一问题而发展起来的 .MES是面向执行的工厂层信息系统 ,为 ERP系统和控制系统提供关键联接 ,能自动执行计划层制定的生产计划 ,从收集的实时数据中提取ERP系统所需的正确信息 ,使企业中需要相互联系的各信息系统和以产品生产为纽带的各部门紧密联系、协调运作 ,使企业获得最大的效益 .本文介绍了 MES产生和发展 ,在 MESA模型的基础上提出由计划执行与工厂管理、数据采集与处理两大部分组成 ,包含 10个模块的 The plans made by customer oriented ERP system for the whole enterprise should be executed based on the actual conditions of plants. But there are often some differences between plans made by planning floor and actual capabilities of plants because of the limits of ERP itself, dynamic characteristics of plants and a lot of undetermined factors in plants. So Manufacturing Execution Systems were created to solve this problem. They are execution oriented information systems. MES provides the critical link to fill the gap between ERP and control systems. MES can execute automatically production plans made by planning floor, extract the correct information for ERP from collected real time data. MES enables information systems to be interconnected with each other closely and production departments to work in harmony. Consequently, enterprises get maximum profits. In this paper, we explain why MES was created and introduce the development of MES. Based on MESA model, a MES functional model is proposed that comprises two major parts, one related with plan execution and plant management and the other related with data collection and processing. There are 10 functions in the model.
