Optimal Study On Supplier Performance Evaluation Scheme Of Shanghai YFA Company

With the development of modern economy and science and technology,automobile industry has gradually become one of the pillar industries of China’s manufacturing industry.From 2010 to 2017,it has been in a high-speed growth stage.This trend was broken in 2018.With the downward trend of the whole industry chain,the auto parts manufacturing industry declined for the first time,and this decline continues in 2019.Yfa company is the "leader" in China’s auto parts manufacturing industry,and has been committed to the intensive cultivation of auto seat products.Under the background of the declining trend of the industry,in order to match the development strategy of the enterprise,yfa company urgently needs to reform in the aspect of supplier management,continuously reduce the cost of existing suppliers,and make the whole supplier system more suitable for the development of the current enterprise.Suppliers become an important part of the overall development strategy of yfa company.Supplier performance evaluation system has become the final and most important part of yfa company’s supplier system,and it needs to be optimized in the face of many problems brought by the old system.Through the sorting out and induction of the relevant theories of the supplier performance appraisal system,this paper finds that in the previous studies,scholars put forward multiple evaluation indexes according to the situation of the industry or case studied,but no scholars have summarized and summarized the currently widely recognized main indexes in the way of data model according to the specific situation of the enterprise,sorting out the indexes with general industry adaptability Index system,and although the research object is automobile enterprises,most of them focus on vehicle manufacturing enterprises.There are very few automobile parts and components,so it is impossible to build the system according to the characteristics of the parts and components enterprises,forming the guidance for the parts and components industry.Therefore,in the process of research,in addition to summarizing the previous scholars’ research,combined with the data,materials and survey results collected by the author in daily work about the company’s supplier management and assessment,this paper uses the effective methods of literature research,case analysis,qualitative analysis,quantitative analysis and other research topics to select indicators,so as to make it more consistent with the research The overall characteristics of the auto parts industry,and has a wide range of adaptability.Then,using the mathematical model of random forest method,starting from the current situation of the supplier performance appraisal system of yfa company,this paper makes an in-depth study on the supplier performance appraisal system of yfa company,and clarifies the problems existing in the current system of yfa company,such as strong subjectivity,lack of practicability,poor coordination,etc.through the analysis of these problems and causes,the paper uses random forest method to build yfa The optimization model of the company’s supplier performance appraisal system determines and verifies each evaluation index and consistency,and finally determines the method of yfa company’s supplier performance appraisal,deduces the calculation process,and carries out case analysis and effect verification and summary to verify the effectiveness of the new system and the improvement of supplier quality.The research of this paper finally optimizes the supplier performance appraisal system scheme which is more suitable for the current development of yfa company,and verifies and summarizes the effectiveness of the implementation results of the system to help yfa company improve the level of supplier management,achieve the goal of selecting the best supplier,and achieve the goal of maximizing the enterprise benefit at the level of supplier evaluation.
