Consider stochastic production-inventory control problem in which there are multiple capacity sources, multiple heterogeneous products, non-stationary demand and time-varying costs. If shortage costs can be evaluated the natural objective is to minimize expected production, inventory and shortage costs. Otherwise one can use service level requirements as target inventory while trying to minimiz...
