Assume that we have a transportation network that includes two origin provinces, two transshipment provinces, and three destination provinces from the country Orsinia. In the figure below, you can find the arcs, nodes, and the capacity and demand values of each node on the figure. These values represent product amounts.

As a special case, Molsena is a transshipment point but also has its own demand (30 units). You can find transportation costs between each node in the table below.
