We propose and analyze robust optimization models of an inventory management problem, where cumulative purchase, inventory and shortage costs over n periods are minimized for correlated non-identically distributed demand. We assume that the means and covariance matrix of stochastic demand are...

In this paper, we consider a supply-chain model consisting of a single product, one supplier, and multiple retailers. Demand at the retailers is random, but stationary. Each retailer places her orders to the supplier according to the well-known (Q,R) policy. We assume that the supplier has...
