Research On Single-source And Dual-source Procurement Of H Company Under The Risk Of Uncertain Supply Quantity

Economic globalization has extended the space and time of the supply network in the manufacturing industry,and has appeared lean,complicated and globalized.At the same time,consumers’ consumption habits are also changing.From the previous commodity prices and quality to the speed and characteristics of commodity acquisition,in order to meet consumer demand,companies have to improve their responsiveness.In recent years,frequent occurrence of natural disasters,terrorist attacks,worker strikes,and the impact of environmental protection departments,supply disruptions have occurred from time to time,and supply uncertainties often require manufacturers to temporarily change production plans,which will bring some adverse effects,Such as cost value and poor customer experience.Stable supply is an important guarantee for the supply chain to create value,reduce costs and improve services.This paper studies the procurement strategy of H Company under the risk of uncertain supply quantity.First of all,an analysis was conducted on Company H.During the conversation with the person in charge of the company,it was learned that the company almost stopped working every month.Through fishbone analysis and brainstorming,the root cause was found and plastic During the manufacturing process,whether it is a merchant,a supplier,or a superior supplier,it is subject to the supervision of the environmental protection department,and the supply of raw materials is insufficient or interrupted from time to time.Secondly,combined with the newsboy model,establish a single-cycle single-source procurement model;at the same time,increase supply sources,establish a dual-source procurement strategy with emergency suppliers and a dual-source procurement strategy with dual supply risks,and find the best The optimal solution,as well as the procurement ratio,discuss the versatility of the model,and analyze the impact of the supply quantity reliability factor and supply interruption factor on the expected profit.Then combine the three procurement strategies with Company H.According to the actual situation of Company H,the company’s procurement is divided into two parts:low season and high season.Analyze the procurement strategy that is most suitable for the company under different circumstances.Finally,on the basis of the single-cycle procurement strategy,the dynamic programming method is used to study H company’s multi-cycle procurement,and a multi-cycle procurement plan is formulated for H company.For the manufacturing industry,the main cost of an enterprise is raw materials or parts,and the focus of manufacturing is how to reduce procurement costs.This article takes H company as an example,combined with the actual situation of H company,to optimize the procurement strategy of H company.Through the comparison of the models,it is found that dual source procurement is more favorable to deal with the shortage of supply,but when the supply reliability is relatively high,single source procurement is more conducive to saving procurement costs.This is of guiding significance for the procurement of H Company and the determination of the procurement volume.
