Manufacturing Company Manufacturing Execution System Design And Implementation

Manufacturing Execution System (MES) is a new type of manufacturing process-oriented information system for workshop production management and control. The system receives production plans from production management information system, is held responsible for the execution of the plans in real production, and directs the production activities. It also provides real-time accurate feedback to the production management system about those plans. Obviously, it's a bridge between top-level management and low-level control system, and is the key for the integration of all enterprise information systems and implementation of advanced manufacturing strategy. For the actual requirement of a manufacture company, in the thesis, the thought of software engineering is adopted. The design idea and development procedure of the manufacture executing system which is applicable and reusable to the company is also elaborated. The main author's work is described briefly as follows:Firstly, the MES's definition, position, basic functions and situation in practice are introduced generally. Its deficiencies in research and engineer practices are analyzed. And the Standardization processes of MES are proposed.Secondly, based on the research of the company's current production flow, the information integration relationship and system borders are described. The system functions and non-functual requirements are generalized. The function models also are divided and detailed.Thirdly, to make the MES reusable, anti-amendable, efficient and easy-to-use, the system is generally designed with the framework and object-oriented method. Models for production tasks are developed based on C/S. Synthesis selection and production information models are realized based on B/S. Oracle 9i is adopted for database. The designation and some date sheets are explained in the thesis.Fourthly, models realized by author such as plan management and processing operations management are elaborated. The corresponding model testing is also finished and interpreted.
