Research On Procurement Strategies Of Dual Suppliers Under Unreliable Supply And Uncertain Demand

With the rapid development of economy and the rapid progress of science and technology,our country has experienced from agricultural society to industrial society,and the evolution of the information society.Under this background,with the continuous improvement of technical specialization and the rapid development of the global market,it is difficult for enterprises to complete complex production activities relying only on their limited means of production.In this way,the optimal allocation of resources among enterprises is emerged through procurement and other trading methods.In recent years,supply chain management,as the main way for enterprises to conduct production management and participate in market competition,has won efficiency and cost savings for the procurement,production and sales of enterprises.However,with the increasing complexity of supply chain structure and external environment,product quality,natural disasters,international political environment and other factors,enterprises are facing increasing supply chain risks,and supply uncertainty has become a key factor affecting the success of manufacturing enterprises.In order to actively respond to the impact of possible supply risks on production activities,it is of great significance for enterprises to develop and implement effective preventive measures to deal with supply risks.Due to the fierce market competition and complex supply chain structure,manufacturing enterprises face the risk of supply uncertainty and demand uncertainty.It is an effective way for enterprises to avoid risks by formulating appropriate procurement strategies and determining the appropriate quantity of purchases.At present,domestic and foreign procurement research mainly focuses on dealers and retailers,and there are few studies on the procurement of raw materials for manufacturing enterprises.From the perspective of manufacturing enterprises,this paper studies the optimal selection of procurement strategy and order allocation when faced with two suppliers in the uncertain market demand environment.(1)in order to solve the procurement decision-making problem of manufacturing enterprises,through the uncertain environment analysis and procurement strategy comparison,combined with the actual situation of enterprises,to build a research framework of double supplier procurement strategy of manufacturing enterprise under the uncertain supply environment.(2)in order to solve the problem of enterprise procurement decision-making of single-risk suppliers in the environment of uncertain demand,the model of dual source procurement and backup procurement is established.The sensitivity analysis and comparative study of the two models are carried out in order to provide management enlightenment for purchasing mode selection and order quantity decision of manufacturing enterprises.(3)in order to solve the problem of enterprise procurement decision of double-risk suppliers in the environment of uncertain demand,the dual source procurement and backup procurement model is established.The sensitivity analysis and comparative study of the model are carried out in order to support the procurement model selection and order quantity decision of manufacturing enterprises in the face of dual-risk suppliers.
