Supply Chain Procurement Decision-making Considering Risk Aversion in Event of Supply Disruption
In recent years,the globalization of supply chains has promoted the deep integration of indus-tries across countries and regions,but it is also accompanied by higher risk of supply chain disruption,which is further exacerbated by various emergencies such as regional conflicts and natural disasters.How to make procurement decisions under unstable supply conditions and pursue maximum benefits has become a key is-sue of concern to all sectors of society.Existing studies generally discuss how retailers can make decisions to achieve optimal benefits from the perspective of risk aversion or supply disruption.However,in real life,re-tailer's attitude toward risk aversion depends to a certain extent on the supply situation,and their procure-ment decisions are affected by historical supply data.However,few literatures comprehensively consider the procurement problem during supply disruptions under the combined effects of historical data and risk aver-sion.Based on this,for a two-echelon supply chain consisting of one retailer and two suppliers,the supply chain procurement and pricing decisions considering risk aversion are discussed under two different situa-tions:procurement quantity is allocated according to demand function or by proportion during supply dis-ruption.The results show that:(1)The optimal procurement quantity of the retailer decreases as the suppli-ers'supply capacity increases;the supplier with high supply disruption risks has lower pricing power than the more stable supplier;and supplier profits do not decrease as procurement quantity decreases.(2)When the procurement volume is allocated proportionally,the optimal procurement volume of the retailer shows an overall downward trend.At this time,the suppliers can be regarded as a whole.The orders received by the suppliers are inversely proportional to product pricing.A seemingly more stable allocation proportion will cause the suppliers to become negative towards improving supply capacity.The supplier with poor supply ca-pacity will guarantee profits by raising prices,which will damage the profits of the retailer.(3)In both cases,the addition of risk aversion will raise the optimal price of the suppliers.At the same time,the procurement volume of the retailer will also increase with the risk aversion coefficient;the profit of the supply chain will tilt towards the suppliers,and the profit of the retailer will decrease.The research results can provide manage-ment inspiration for how retailers make procurement decisions when facing the risk of supply chain disrup-tion in real market situations.
