Separation results for multi-product inventory hedging problems
- 215 Downloads
We analyze financial hedging tools for inventory management in a risk-averse corporation. We consider the problem of optimizing simultaneously over both the operational policy and the hedging policy of the corporation in a multi-product model. Our main contribution is a separation result such that for a corporation with multiple products and inventory departments, the inventory decisions of each department can be made independently of the other departments’ decisions. That is, no interaction needs to be considered among different products.
