Model Overview. The Network Flow Contested Logistics (NFcL) model is a logistics planning tool designed to simulate logistics network operations by sea, air, ...

A new model based on the blood-vessel network in a rat brain shows that the vessel position within its circulatory network does not influence the blood flow nor how nutrients are transported. Instead, ...

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 ...

Network Flow-Graph Rules The first rule is the “Series Rule.” Because b1 = j * a1 and a2 = b1 * k, then a2 = j * k * a1 and one can break out the connection from a1 to a2 (Fig. 2) .

Previous maximum flow algorithms made steady and incremental advances, but they still took longer to find the optimal flow than to process the network data. But the new research, ...
