In this paper, we analyze a generalization of a classic network-flow model. The generalization involves the replacement of deterministic demand with stochastic demand. While this generalization ...

We consider a problem in which a fleet of vehicles must be scheduled to pickup and deliver a set of orders in truckload quantities. We describe a new algorithm based on a network flow relaxation which ...

In this paper we develop a policy model for pollution control investment and operational decisions in the copper industry. The system consists of (i) a nonlinear integer model to optimize smelter ...
