Research On Supplier Selection Evaluation Modeling For The Enterprise

With the increasingly fierce market competition and the rising prices of raw materials, raw material purchasing cost accounts for 60 percent of the whole cost. Thus whether there is effectively stable supply and the quality of partners are important factors related to the sustainable development of enterprises. How to establish supplier selection and Evaluation system which is matched with enterprise management, using what method to evaluate suppliers is an important issue faced by enterprises currently.This paper takes the tire enterprise supplier selection as the research object, based on supplier selection theory, AHP and Kraljic combination matrix model, by combining qualitative analysis and quantitative model then constructed the supplier selection evaluation model of the tire industry.Firstly, after analyzing the status of enterprise supplier selection and evaluation of tire industry, this paper summarizes the existing problems. Then the methods and steps of tire enterprise supplier selection evaluation optimization is proposed and The futures tools applied to tire industry raw materials procurement process is feasible.Secondly, according to the principles of establishing supplier evaluation index system, this paper develops a procurement position evaluation index system and selects the index and weight from material importance and supply risk using the delphi method and analytic hierarchy process. Then four types of the tire enterprise procurement and the corresponding purchasing management strategy is obtained with some pareto division.Furthermore, user interface is completed with matlab,7.0, andsupplier comprehensive evaluation index system is established for every type of procurement. And the indexes are evaluated using the analytic hierarchy process. According to the evaluation results suppliers are divided into strategy, important and general ones with the procurement positioning classification of tire industries differentiate, then this paper expounds differentiation management strategy of three types.Finally, taking a tire enterprise as an example, the model is applied to verify its supplier selection. Result proves that the evaluation model given by this paper has strong applicability and superiority.
