文摘
- •
A supply chain with stochastic lead-time and ARMA demand is considered.
- •
Exact expressions are obtained for the distributions of order and inventory.
- •
Under order crossover, the order-up-to policy does not minimize inventory variance.
- •
Inventory variance minimization by proportional policy also reduces bullwhip.
- •
This ability is compromised under some demand auto-correlation cases.
