This paper treats a depot-warehouse system in which demand occurs at the warehouse or retail level. This work differs from a number of other studies in that we allow item demands to be correlated both across warehouses and also correlated in time. Our motivation for this generalization arises...

Public health budget constraints force policy makers to prioritize resources toward those interventions that yield the highest perceived benefits. Intuitively, it appears optimal to focus resources on affordable interventions against prevalent diseases. However, due to the dynamics of infectious...

We investigate the problem of determining optimal planned leadtimes in serial production systems in which the actual procurement and processing times may be stochastic. The objective is to minimize the sum of inventory holding costs and job tardiness costs given a customer specified due-date. We...

For most order quantity/reorder point inventory systems, the stochastic model, which specifies the demands as stochastic processes, is often more accurate than its deterministic counterpart---the EOQ model. However, the application of the stochastic model has been limited because of the absence...

This paper constructs and analyzes a multi-location inventory model to examine the value of warehouse risk-pooling in high service-level systems. Specifically, risk-pooling over the outside-supplier leadtime is examined. Two alternative systems of N identical retailers are formulated. In System...
