Study On The Design Of Supplier Evaluation Indexs System And Model Of Company ZC

In recent years,China's marine diesel engine manufacturing industry has made rapid development,nevertheless,related enterprises are facing with low industrial concentration,lack of market competitiveness and other urgent problems to be solved.In order to better cope with the fierce market competition,marine diesel engine manufacturers must change the development mode,seek long-term and stable strategic cooperative relationship with suppliers and promote the common advancement of both sides.From this point of view,the development of supplier management plays a very important role in promoting the development of enterprises.ZC Company as a marine diesel engine manufacturers,procurement costs accounting for up to 80% of the company's production costs,the quality of suppliers on the smooth development of production and operation activities have a great impact.With the change of development mode,ZC Company and suppliers are gradually changing from traditional supply and demand relationship to long-term stable cooperation mode.Therefore,it is of great significance to construct a set of supplier evaluation system really suitable for ZC company,which is very important for the improvement of its production efficiency,the control of production cost and the enhancement of its core competitiveness.At present,although some scholars have studied the supplier evaluation of marine diesel engine manufacturing enterprises,with fewer research results,outdated evaluation index and too subjective evaluation method,it is difficult to meet the needs of enterprise development.In view of this,this paper proceeds from the actual situation of ZC Company,and the evaluation of its suppliers is deeply studied.Firstly,this paper analyzes the present situation and existing problems of supplier evaluation of ZC company from the aspects of purchasing and supplier management of ZC company and supplier evaluation index system and method.On this basis,the evaluation index is analyzed and screened by means of questionnaire survey and factor analysis,and a new supplier evaluation index system is constructed,and the quantitative description of the index is given.Then,on the basis of analyzing the actual requirements,the BP neural network model based on genetic algorithm optimization is selected as the supplier evaluation method of ZC company.The model has good learning ability and can evaluate suppliers objectively and dynamically,so as to avoid the influence of human subjectivity to a great extent.Finally,on the basis of evaluating and sorting the suppliers by using the evaluation model,the suppliers are graded.Using the foreground theory and the double reference point theory,according to the different grades of suppliers,the satisfaction degree of the supplier and the enterprise itself is calculated from two angles of order ratio and sample sampling ratio,and the order proportion and sampling proportion are solved when the comprehensive satisfaction is maximized by genetic algorithm.Based on this,develop and cooperate with different levels of suppliers.Based on the actual needs of the company,this paper makes an in-depth study of the supplier evaluation of ZC company from two aspects of the construction of Evaluation Index system and evaluation model,and gives the method of supplier cooperation strategy development based on the evaluation results.The research on supplier evaluation of ZC company and other marine diesel engine manufacturers has a good application and reference value.
