Research On MES System For A Aviation Manufacturer

A aeronautical manufacturing enterprise is facing problems with production plan, operation monitoring, information flow and database integration. These operations management problem urgently needs to solve. In order to improve A enterprise production and operation ability, the thesis uses the Manufacturing execution system (MES) theory and method for management, constructs and researches MES system on production management system of A enterprise. Finally, the function module of MES system in aircraft assembly, parts manufacturing, production planning in the automatic scheduling, planning adjustment of application analysis and verification, the application of function module of MES system in the information communication and database management are analyzed.Firstly, the thesis carries on the general situation, organization structure, production management system, product features and realization process of A enterprise is introduced, and the problems of production management system analysis. Secondly, the MES system overall structure design of A enterprise and the problem solution is proposed. The overall structure design includes three levels that are planning layer, execution layer and control layer. Then, the thesis selects the appropriate model construction and function module of MES system, from the assembly manufacturing plan, parts manufacturing plan, supporting demand plan and tooling manufacturing planning several aspects put forward the plan optimization scheme. Optimization scheme of plans including assembly manufacturing plan, parts manufacturing plan, supporting demand plan and tooling manufacturing planning aspects is proposed. Finally, the thesis analyzes and verifies application in automatic scheduling and planning adjustment for aircraft assembly and parts manufacturing in the function module of MES system. And analysis and discusses the application of MES system function module in the information communication and database management.Application of MES system provides the production and operation of integrated management platform for A aeronautical manufacturing enterprises. The system can optimize production planning, makes a more rational allocation of resources, improves the work efficiency, and saves the cost of management. The system can also realize statistical analysis of the data and information resource sharing function, and improves the comprehensive management level.
