Research On Supplier Selection Of T Company Based On Dynamic Hybrid Multi-attribute Decision Makin

With the development of market economy,the status of small enterprises is constantly improving,and small enterprises are also the cradle of medium and large enterprises.Only when small enterprises continue to grow,more medium and large enterprises can emerge.However,with the change of market environment,the profit space of manufacturing small enterprises is shrinking,and they are faced with severe challenges.This paper takes T Company’s supplier selection as the research background,analyzes the main problems in supplier selection and seeks solutions: First of all,the supplier evaluation index is single and subjective,so this paper uses Delphi method to determine the evaluation index,and uses G1 method to calculate the index weight.This method can not only avoid the problem that the consistency test of AHP method with a large number of indicators is difficult to pass,but also preserve the order in a certain period.Secondly,when selecting suppliers,T Company only considers the horizontal comparison of the prices of suppliers at a certain time point,and does not pay attention to the dynamic changes of various indicators.This paper collects the dynamic data of consecutive periods,and determines the time weight to aggregate the dynamic data according to the principle of thick and thin,and constructs an indicator system convenient for comprehensive evaluation of suppliers.Third,T company supplier selection is not scientific and systematic selection methods,because of T company selected indicators there are both precise numerical index,interval type index and semantic language,so in this paper,according to the characteristics of the hybrid multi-attribute index modular,The dynamic intuitionistic fuzzy decision theory method after the semantic language index is converted into intuitionistic fuzzy number can effectively avoid the data distortion caused by the conversion of intuitionistic fuzzy number index to accurate value.At the same time,the positive and negative ideal solutions of each module are calculated separately with TOPSIS thought.Finally,the ideal solutions of each module are weighted to get the final ranking of the solutions.Based on this,the dynamic comprehensive evaluation model of suppliers is established to select the best solution.Based on this,a dynamic comprehensive evaluation model of suppliers is established.The semantic language index is converted into intuitionistic fuzzy number,and then the dynamic intuitionistic fuzzy decision theory method can effectively avoid the data distortion caused by the conversion of intuitionistic fuzzy number index to accurate value.Through the research of this paper,it can provide a simple and practical method for T company to choose suppliers,and also provide quantitative basis for other similar dynamic mixed multi-attribute decision-making problems.
