In order to avoid the loss of interests and the increased costs, managers must find the corresponding strategies. And this study is to explore the issues of supply risks between suppliers and retailers. 　　The theme of this study is about how a retailer making effective sourcing decisions between two suppliers. The primary supplier offers lower prices, but with lower reliability in the supply of raw materials or products, that makes the supplies uncertain, and even with disruptions. The other supplier is called the backup or emergency supplier which holds near-perfect supply reliability, but its price is relatively expensive. For the unstable supply of the primary supplier, this study make capital investments for “setup costs” and “standard deviation of yields” . When the supply disruption occurs, the retailer would not use the backup supplier immediately. If the primary supplier cannot recover from the disruptions in the duration of waiting time, the retailer will use the backup supplier which has higher supply reliability. In this dual sourcing model, this study developed and listed all relevant cost items and minimizing the final total cost.
