The Study Of Quality Risk Evaluation In High-generation TFT-LCD Plant Clean Room Construction Project Based On AHP

With the development of display technology, the cathode ray tube monitors have quit the stage of history, TFT-LCD that is due to the thin-film transistor liquid crystal display TFT-LCD has a small size, light weight, low radiation, low power consumption, full color, etc., has occupied the mainstream market. LCD display is divided into 1 to 10, on behalf of behalf of the production line, high-generation herein, refers to more than six generations and generations. At present, China has a number of high-generation TFT-LCD panel production line in operation, there are 10.5-and 11 on behalf of the production line in China ready to build. High-generation TFT-LCD plant clean tight schedule, investment, technical requirements of the clean, high degree of process automation, micro-vibration demanding. At present, the project risk management focused on large-scale infrastructure projects high-speed rail, highways and other, less research direction for plant construction, high-generation TFT-LCD plant clean industrial projects as the research object, there is a certain representationIn this thesis, based on the theory of risk management project to clean high-generation TFT-LCD plant construction project for the study, experts in related fields to learn and adopt the existing research results, combined with the actual characteristics and status of high-generation TFT-LCD plant construction project clean through with the project manager, the technical staff, construction workers and companies engaged in risk management team related to those skilled in similar projects consisting of in-depth interviews, the high-generation TFT-LCD clean plant construction project in accordance with the actual progress of the divided preparation, implementation, ending three phases, combining the different characteristics of the various stages of interview, brainstorming and the Delphi method, to identify possible risks, by WBS-RBS method of high-generation TFT-LCD plant cleanliness analysis risk factors of construction projects, to ensure its accuracy and objectivity. By analyzing the structure of AHP judgment matrix associated risk factors, risk factors importance sort. Finally, in order to clean a TFT-LCD plant construction project in Chongqing as a case study, in accordance with the above theoretical approaches to project risk management, analysis of risk management, verification of theoretical research the feasibility and operability.In this thesis, we identify high-risk clean-generation TFT-LCD plant construction projects were studied, and the corresponding actual cases have been proposed based on AHP for the quality of high-generation high-generation TFT-LCD plant construction project clean risk factors evaluation system; and practical cases, quality risk factor authentication application effect evaluation index system. At present, China’s new TFT-LCD production line technology proposed has been a world leader, I hope my research on large-area TFT clean plant construction project has certain reference value.
