Abstract: Based on a two-stage supply chain of periodic production and inventory,the impact of the production variability on the inventory decisions of factories and its downstream retailer under the infinite horizon and discrete time was researched.With the increasing of production variability,the optimal storage inventory and optimal inventory costs were increased.The faster the optimal basic storage inventory increased,the more quickly the optimal inventory costs increased.The optimal storage inventory and optimal inventory costs in the decentralized decision were superior to those in the centralized decision.To discuss the impact of production variability on supply chain's stock decision under the uncertainty of production capacity,a two-stage supply chain model was built,and the inventory subsidy contracts was design to coordinate the stock decision between up and downstream of supply chain,which realized the perfect coordination of supply chain and reduced the inventory cost.

Key words: supply chains, stock, production variability, infinite horizon
