MES（制造执行系统）在企业信息化中的位置是怎样的？美国先进制造研究机构（AMR）通过对大量企业的调查发现现有的企业生产管理系统普遍由以ERP/MRPII为代表的企业管理软件，以SCADA、 HMI(Human Machine Interface)为代表的生产过程监控软件和以实现操作过程自动化，支持企业全面集成的MES软件群组成。数字化转型网szhzxw.cn
根据调查结果，AMR于1992年提出了三层的企业集成模型。一个制造企业的制造车间是物流与信息流的交汇点,企业的经济效益最终将在这里被物化出来。随着市场经济的完善,车间在制造企业中逐步向分厂制过渡,导致其角色也由传统的企业成本中心向利润中心转化,更强化了车间的作用。因此,位于车间起着执行功能的制造执行系统MES具有十分重要的作用,从这模型可以看出，制造执行系统MES在计划管理层与底层控制之间架起了一座桥梁，填补了两者之间的空隙。数字化转型网szhzxw.cn
一方面，MES（制造执行系统）可以对来自MRPII /ERP 软件的生产管理信息细化、分解，将操作指令传递给底层控制；
另一方面，MES（制造执行系统）可以实时监控底层设备的运行状态，采集设备、仪表的状态数据，MES（制造执行系统）经过分析、计算与处理，触发新的事件，从而方便、可靠地将控制系统与信息系统联系在一起，并将生产状况及时反馈给计划层。数字化转型网szhzxw.cn
车间的实时信息的掌握与反馈是制造执行系统对上层计划系统正常运行的保证，车间的生产管理是MES（制造执行系统）的根本任务，而对底层控制的支持则是MES（制造执行系统）的特色。

what is the position of MES (Manufacturing execution System) in enterprise informatization?
what is the position of MES (Manufacturing execution System) in enterprise informatization?American Advanced Manufacturing Research Institute (AMR) found that the existing enterprise production management system is generally represented by ERP/MRPII enterprise management software through the survey of a large number of enterprises. Production process monitoring software represented by SCADA and HMI(Human Machine Interface) and MES software group to realize operation process automation and support enterprise comprehensive integration. Based on the findings, AMR proposed a three-tier enterprise integration model in 1992. 数字化转型网szhzxw.cn
The manufacturing workshop of a manufacturing enterprise is the intersection of logistics and information flow. And the economic benefits of the enterprise will eventually be materialized here. With the improvement of the market economy. The workshop gradually transitioned to the branch factory system in the manufacturing enterprises. Which led to the transformation of its role from the traditional enterprise cost center to the profit center and strengthened the role of the workshop. Therefore, MES, which plays an executive function in the workshop, plays a very important role.
As can be seen from this model, MES builds a bridge between the planning management and the bottom control, filling the gap between the two.
On the one hand, MES (Manufacturing Execution System) can refine and decompose the production management information from MRPII /ERP software. Pnd pass the operation instructions to the bottom control;数字化转型网szhzxw.cn
On the other hand, MES (Manufacturing execution System) can monitor the operating status of the underlying equipment in real time, collect the status data of equipment and instruments. MES (manufacturing execution system) through analysis, calculation and processing, trigger new events. So as to conveniently and reliably link the control system with the information system. And timely feedback the production status to the planning layer.数字化转型网szhzxw.cn
Workshop real-time information and feedback is the manufacturing execution system to ensure the normal operation of the upper planning system, workshop production management is the fundamental task of MES (Manufacturing execution system). And the support for the bottom control is the characteristics of MES (Manufacturing execution system).数字化转型网szhzxw.cn
