In more realistic problems from transportation we usually have to deal with capacity constraints, limiting the amount of flow across arcs. Hence, the basic problem in a capacitated network is to send as much flow as possible between two designated vertices, more precisely from

,Organisationstheoretische Überlegungen,an for period j as a shortest path. If we have capacities on the edges as well, the problem becomes a combination of a shortest path and a flow problem called a min-cost-flow-problem, which is the kind of problem we will discuss in this chapter. Compared to its simplest form, namely when we interpre

Discrete Problems from Applications,rom communications to scheduling in factories, from biology to economics. The field has attracted considerable attention over the last five decades mainly for one reason, namely the availability of powerful computing machinery. Let us motivate our topic with an example.

https://doi.org/10.1007/978-3-8349-9963-4After the abstract algebraic material of the last chapter, this one will be easier and more concrete. We shall deal with the problem of determining a shortest path in a weighted graph. This everyday problem does not only occur in its most obvious form, as we already realized in Chap. 1.
