Research On MES Implementation Model And Implementation Activities Planning

As a management information system between the top production plan and bottom industrial control system, manufacturing execution system can effectively improve the management of manufacturing process, reduce production cost and increase production efficiency. It is gaining more and more attention to manufacturing enterprises. The implementation of manufacturing execution system involves many contents, covers a wide range, so it is a complicated system engineering. The scientific implementation method is important to guarantee the smooth implementation of manufacturing execution system. Although a lot of research work about manufacturing execution system is deployed in our country at present, A more comprehensive, systematic, and detailed implementation methods of MES has not developed. This paper focuses on implementation models and methods of manufacturing execution system.Firstly, the paper introduces the function and role of manufacturing execution system, plans major activities in the process of implementation of MES from project organization layer referring to Nolan stage growth theory, the implementation model of information systems;And plans major activities in the process of implementation of MES from the system layer referring to software engineering system cycle theory;And establishes MES system reference implementation model containing two levels and five stages,and discusses the principles be followed by the implementation of MES system .The paper plans in detail for the activities of five stages , such as activity contents,the expected achievements and activity strategies according to the proposed MES reference implementation model.Finally,the paper plans for the implementation process and activities of MES combining with actual conditions in a manufacturing enterprise and referring to MES implementation model proposed in this paper,and analyzes the effects of the.
