Solver Moment
Figure 6.34 gives the Excel Solver model for the maximum flow model of Example 6.4-2 (file solverEx6.4-2.xls).
The general idea of the model is similar to that used with the shortest-route model, which was detailed following Example 6.3-6.The main differences are: (1) there are no flow equations for the start node 1 and end node 5, and (2) the objective is to maximize the total outflow at start node 1 (F9) or, equivalently, the total inflow at terminal node 5 (G13).
File solverEx6.4-2.xls uses G13 as the target cell.
You are encouraged to execute the model with F9 as the target cell.
