Problem
1. Why might it be more convenient to set up network models in Excel by using a tabular form?
2. How can we manipulate a maximal-flow network model in order to specify all arcs between each pair of nodes (i.e., the entire table) as the changing variable cells in Solver?
3. How can we manipulate a shortest-path network model in order to specify all arcs between each pair of nodes (i.e., the entire table) as the changing variable cells in Solver?
