Inventory cost is over 30 percent of the supply chain cost. Therefore

the study of inventory management plays an important role in that of supply chain management. In a refinery

the outputs of different kinds of oil products are not mutually independent

but closely correlative. For instance

while a refinery produces 500t diesel oil

the output of gasoline is restricted within a corresponding range. Consequently

the inventory management of a refinery should synchronously take sales forecast and production planning into account. Based on sales forecast

this paper integrates stock management and production optimization to study the inventory management of refinery supply chain under demand uncertainty. Stock management strategy and the corresponding algorithm are presented in the paper; reasonable result is obtained by using industrial data.
