Abstract: For a supply chain consisting of two competing suppliers and two competing retailers,the optimal procurement and pricing decisions of retailers was studied when facing supply disruptions.Considering the disruption correlation and responsive-pricing retailers,a three-stage game model was established,and the optimal decisions of suppliers and retailers were obtained respectively.The results showed that:①the price competition between the suppliers was intensified although the diversification benefits were weakened with increasing in the disruption correlation,which made retailers’ profit increase,so retailers should choose the suppliers with highly correlated disruptions;②the more competition among retailers,the more important the reliability of supply,so retailers would purchase from more reliable suppliers;③an increase in the reliability of any supplier would not only benefit the supplier itself but also the retailers.

Key words: supply disruption, dual sourcing, responsive pricing, competing retailers
