Research On The Manufacturing Execution System Of S Company

In recent years, the TFT-LCD industry competition is becoming increasingly fierce,the planning and implementation of enterprise has to make quick response to theunpredicted market environment. Hundreds billions of dollars high equipment investmentwhich let enterprises need to improve the equipment’s utilization rate urgently, meanwhileenterprise’s planning layer’s instructions can’t be transmitted to executive layer in time,and device control layer can’t give feedback in real time and so on， mentioned problemsaffect company’s production efficiency and delivery speed seriously, above making theproduction management become TFT-LCD enterprise’s challenge.This thesis takes S company’s TFT-LCD factory manufacturing execution system asthe subject of study, on the basis of the domestic and foreign manufacturing theory andMES status research of system execution, reviews case study of S company, MES, andcontrast the effect of before and after the implementation on the basis of study. Thesis willstudy on manufacturing execution system consists three parts including problem analysis,MES system function and integrated model, implementation benefit analysis and reference.This thesis analyses S company’s production process, production and planningmanagement status, the existing information systems, focuses on the analysis ofproduction management in the presence of various problem, analyses the reason ofexistence. Research of MES main functions and system integration model of S companybased on the analysis of the reason from the system architecture, architecture, MESsoftware, production planning, process management, product management, qualitymanagement, equipment management, integrated model and research company MESsystem consists of MES and ERP system integration model and equipment, MES systemintegration model, integration model of MES transmission system and automatic move,the data flow and function integration model. Comparative analysis on the implementation of S company’s TFT-LCD plant after the main module of MES benefits, and summarizethe effect of before and after, and puts forward some suggestions for the same industry.
