面向流程企业的可配置MES体系结构

Configurable MES architecture for process enterprise

过程系统工程的概念内涵将企业的经营管理、供应链和MES的运作紧密联系在一起,当企业组织结构调整、工艺过程改造、产品方案变动等发生时,要求MES系统具有对工厂过程和业务过程持续变化的适应能力。本文提出了一种面向流程企业的可配置MES体系结构,包含模型层、协同平台层和功能层3个配置层次,通过模型层实现业务功能与工厂描述分离;协同平台层实现业务逻辑与技术支撑分离,以及实现整体过程协同和全局优化;功能层实现不同厂商产品间标准化的功能接口。最后,以基于可配置体系结构的MES产品(SMES)为例,分析了各层次的实现方式以及对流程企业业务持续变化的适应性验证。

The concept of process system engineering associates operation and management of business and supply chain with the operation of manufacturing execution system （MES）, which requires the adaptive capacity of the constant change of manufacture processes and business processes, on condition that there is a transformation of organizational structure, technological process and product scheme. This paper proposes a configurable MES architecture with three layers （i. e. model layer, cooperation-platform layer and function layer）. Firstly, business function is separated from description of factory by the model layer; then, business logic keeps apart from technical support via the platform layer and the overall process collaboration and global optimization can be put into practice by means of the same layer; ultimately, standardized function interface is designed for different products through the function layer. Taking the case of a configurable MES product （SMES）, the paper analyzes the implementation of the configurable architecture so as to adapt to constant change of business process.
