 Zusammenfassung: Given a network with capacities and transit times on the arcs, the quickest flow problem asks for a `flow over time' that satisfies given demands within minimal time. In the setting of flows over time, flow on arcs may vary over time and the transit time of an arc is the time it takes for flow to travel through this arc. In most real-world applications (such as, e.g., road traffic, communication networks, production systems, etc.), transit times are not fixed but depend on the current flow situation in the network. We consider the model where the transit time of an arc is given as a nondecreasing function of the rate of inflow into the arc. We prove that the quickest $s$-$t$-flow problem is NP-hard in this setting and give various approximation results, including an FPTAS for the quickest multicommodity flow problem with bounded cost.
