A regional wastewater quality management system was modeled as a fixed-charge network flow problem. The model included alternative trunk-line connections, methods of treatment, and variation in system ...

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 ...

A team of computer scientists has come up with a dramatically faster algorithm for one of the oldest problems in computer science: maximum flow. The problem asks how much material can flow through a ...

In many streams and rivers, water moves between the open channel and the adjacent groundwater. This exchange enables biological and chemical reactions in the sediments near the streams. These ...

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 ...

With rapid globalization and technological advancements manifesting at rising rates, the complexity of logistics networks has increased exponentially. This is most evident in the military sector where ...
