Forreadability, you can use descriptive Excel range namesinstead of cell names.A
range is created by highlighting the desired cells, typing the range name in the top left
box of the sheet, and then pressing Return. Figure 2.14 (file solverRM2.xls) provides
the details with a summary of the range names used in the model. You should contrast
file solverRM2.xls with file solverRM1.xls to see how ranges are used in the formulas.
To solve the problem, click Solve on Solver Parameters (figure 2.14).A new dialogue box, Solver Results, will then give the status of the solution. Ifthe modelsetup
is correct, the optimum value ofzwill appear in cell D5 and the values of Xl and X2 will
go to cells B13 and C13, respectively. For convenience, we use cell Dl3 to exhibit the
optimum value ofz by entering the formula =D5 in cell DBto display the entire optimum solution in contiguous cells.
If a problem has no feasible solution, Solver will issue the explicit message
"Solver could notfind a feasible solution." Ifthe optimal objective value is unbounded,
Solver will issue the somewhat ambiguous message "The Set Cell values do not converge." In either case, the message indicatesthat there issomething wrong with the formulation of the model, as will be discussed in Section 3.5.
TIle Solver Results dialogue box will give you the opportunity to request further
details about the solution, including the important sensitivity analysis report. We will
discuss these additional results in Section 3.6.4.
