In the "polymatroidal" network flow model introduced in this paper, flows are constrained by the capacities of sets of arcs. Yet the essential features of the classical model are retained; the ...

The effects of technological enhancements, such as automation and robotics, will also improve network flow outcomes to the extent possible given the model’s capacity for data inputs.

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.

The network flow model provides a lower bound and a nearly feasible solution that can be made feasible with some simple heuristics. Our algorithm is fast and has performed well on a set of more than ...

Flow data Most routers and switches which operate at layer 3 of the OSI model will have flow export options. There are many flow standards around and they include NetFlow, sFlow and IPFIX.
