Research On The Classification And Selection Of Suppliers Of LCD Panel Manufacturers

In recent years,the domestic panel industry has risen rapidly and will soon become the largest gathering place for production capacity in the world.Due to the characteristics of panel manufacturing with many raw materials,long production cycles,and complicated processes,suppliers must be categorized and managed.The characteristics of the upstream industry chain are weak,the midstream panel manufacturing converges to China,and the downstream market has a broad supply chain,making upstream dominance an important feature of the industry's development.At the same time,there are phenomena in the industry that the gross profit of the upstream and downstream companies is significantly better than that of the middle panel manufacturers.Therefore,establishing a cooperative relationship with suppliers and improving the supplier management level is an important means to further expand the profit margin of panel manufacturers.On the basis of reviewing relevant literature,this article analyzes current research status and deficiencies,studies the current status of the global and domestic LCD panel industry,and explores the problems in the evaluation of supplier selection in the LCD panel manufacturers,with systems engineering,management,and economics.Based on the theory of statistics and other theories,a supplier classification index system and a new classification model conforming to the characteristics of the panel manufacturers were proposed,an objectively confirmed supplier evaluation model was constructed,a comprehensive evaluation of suppliers was conducted,and further cooperation strategy was given.The aim is to build a more systematic and comprehensive selection process for the selection of liquid crystal panel manufacturers suppliers and promote the development of the panel industry in China.The main achievement of the following research results:(1)A supplier classification method using AHP and FCM is proposed to construct a liquid crystal panel manufacturer supplier classification model.Different from previous scholars' research,combining the characteristics of the liquid crystal panel industry,on the basis of the Kraljic Model,a raw material supplier classification index system that comprehensively considers the impact of revenue,supply risk,and product impact has been established.Using AHP to determine the weight of each classification index,FCM fuzzy clustering method was introduced to classify suppliers.HX company was used as the object of supplier classification analysis to verify the applicability and applicability of the classification model.The proposed supplier classification model compensates for the current lack of subjective classification,incomplete consideration of factors,and rigid classification.(2)The DEA-based supplier evaluation model was constructed,and an effective DEA supplier was selected.After considering the modern market competition environment,supply chain management ideology,and evaluation index system construction principles,combining the characteristics of the industry and the needs of the company,the panel manufacturer supplier evaluation index system was established from three perspectives of strategy,focus,and general.Principal component analysis was used to eliminate the possible correlation between indicators.The main components of the extracted input and output indicators were used as comprehensive input and output indicators for supplier evaluation.A supplier evaluation model based on DEA was constructed,and the model was applied to HX Corporation.The model evaluation results show that this method can avoid the influence of unstable factors when the subjectively determine the weights on the evaluation results,and provide improvement measures to improve the level of suppliers,to meet the liquid crystal panel manufacturers want to work closely with upstream suppliers,expand the demand for profit space.(3)The cross-efficiency DEA was introduced and the basis for establishing a cooperative relationship with an effective DEA supplier was given.In order to eliminate the disadvantage that DEA can not further distinguish the ordering of multiple effective decision-making units,the cross-efficiency DEA was introduced,and the effective decision making unit was further evaluated based on the longitudinal comparison of effective decision-making units based on the "his assessment" thought.The company determines the best supplier to provide the basis.The research results show that the proposed method makes up for the lack of DEA in the evaluation of effective decision making units and makes the results more objective and reasonable.
