A Study of Partial Backorder Policy under Random Demand

A Supply Chain Model is developed when partial demand is lost while stocking out. Random demand of a single product with a short lifecycle is satisfied by a retailer and a supplier. When stock-out happens some demand will be lost. Retailer adopts a partial backorder policy to improve his profit level. Optimal quantity decisions are analyzed between integrated supply chain and a decentralized one. Service levels in these two situations are respectively developed. Vertical competition under exogenous random demand has a negative effect on the supply chain: the retailer orders less and the service level decreases. When the supplier is a leader and set the wholesale price to the retailer, a Stackelberg equilibrium is reached between order quantities of the retailer and the wholesale price of the supplier.
