The Design And Realization Of Manufacture Execution System Suitable For Automobile Manufacture

As the pillar industry in many countries, automobile industry represents the industriallevel and affects the national economy of the country. So how to improve the competitivenessof the automobile industry becomes more and more important. With the development ofinformation technologies and modern management maturity, speeding up the informatizationof automobile industry has become an urgent need in improving management level. So how tochoose and apply a suitable information system has become a key problem.MES (Manufacturing Execution Systems).It is a kind of workshop-oriented productionmanagement technology and real-time information system. MES directs, imparts, responsesand report various activities in the workshop through controlling and using the exact real-timemanufacturing information. MES can offer a fast reaction, flexible environment ofmanufacturing industry finely melting to user, help enterprise lower cost, deliver, improvequality of product and raise the service quality on schedule. MES can help to optimizeresource allocation, straighten out business process, enrich management method and finallyenhanced the competitiveness. So the application of MES in automobile industry may bringout new development opportunity for enterprise.According to the production law and informatization need, an MES is abstracted, whichis suitable for automobile manufacture, comprehensive in functions, flexible in configuration,strong in integration and adaptability, easy to extend and stable in security. MES is designedand realized through a deep analysis on the functions, thus a reasonable and effective solutionwhich can improve production efficiency and make enterprise value maximum is provided tothe production management system of automobile manufacture.This paper firstly introduces the related technique and method of MES system. Mainlydiscussing the information acquisition technology(including barcode identification technologyand RFID technology),and research methods of production scheduling(including methodsbased on rule、 artificial intelligence and operations research).Simply discussing thedevelopment tools、the key structure and choice between B/S and C/S and database. In orderto make upgrade and maintenance more flexible, every technology and method mentioned inthe paper is accorded to the practical needs so the integrate capability is promoted.Aiming at automobile manufacture process and production characteristics, the generalgoal is put forward through summarizing and analyzing the deficiencies and needs in current system that is orchestrating the material information, controlling the quality and managing theprocess. According to analysis on logic and process, the system is divided into basicinformation management, product trace and pedigree record, production schedule, qualitymanagement, process management and etc. Each subsystem is analyzed and designed in detail.Finally aiming at the function characters of each module, this paper analyzes the needs ofdatabase and illustrates the key data sheet and typical table structure.The core function module is designed and realized in chapter4. The module of basicinformation maintenance which can simplify the exploitation amount and enhance theadaptability is used to configure users’ authority flexibly. The module of product trace andpedigree record can help operators collect and understand the production information andprovide information for the subsequent functions. The module of production schedule canhelp managers understand and master the production progress, analyze every factor thataffects production and finally minimize the errors according to correspondingcountermeasures. The module of process management is mainly used to monitor productionand provide countermeasures for operators to correct and improve the activities during theproduction process. The module of quality management is used to collect data that existquality problems, provide convenient and quick input and realize statistics and report.The feasibility and rationality of the system are proved by realizing the functions of MES.This paper solves some common problems in MES, that is, the maintenance is poor, theprocess management is difficult, the progress control is not correct, the quality management isnot systematic and the integration is not good. A realistic and effective solution is provided tobroaden the thoughts and lay a foundation for the future research.
