Draw the network for this transportation problem. We do not use multiple arcs within a network because we can combine those arcs into a single arc. To combine two arcs into a single arc, we add their capacities and their flow values, and assign those to the new arc: • Given any two nodes u and v, having two arcs from u to v with capacities c1(u,v) and c2(u,v) respectively is equivalent to considering only a single arc from u to v with a capacity equal to c1… software polimi https://marketingsuccessaz.com
