The macro function must return 1 if Solver should stop (same as the Stop button in the Show Trial Solution dialog), or 0 if Solver should continue running (same as the Continue button). Function called because the Maximum Feasible Solutions limit in the Solver Options dialog was exceeded.Function called because the Maximum Subproblems limit in the Solver Options dialog was exceeded.Function called because the Iterations limit in the Solver Options dialog was exceeded.Function called because the Max Time limit in the Solver Options dialog was exceeded.Function called (on every iteration) because the Show Iteration Results box in the Solver Options dialog was checked, or function called because the user pressed ESC to interrupt the Solver.The argument Reason is an integer value from 1 to 5: The ShowRef macro must have the signature Function name (Reason As Integer). This macro is then called, in lieu of displaying the Show Trial Solution dialog box, whenever Solver pauses for any of the reasons listed below. You can pass the name of a macro (as a string) as the ShowRef argument. False or omitted to return the results and display the Solver Results dialog box.
True to return the results without displaying the Solver Results dialog box. If Solver.xlam does not appear under Available References, click Browse and open Solver.xlam in the \office14\library\Solver subfolder.
In the Visual Basic Editor, with a module active, click References on the Tools menu, and then select the Solver.xlam check box under Available References. Equivalent to clicking Solve in the Solver Parameters dialog box.īefore you use this function, you must establish a reference to the Solver add-in. On each worksheet explain more about each Solver model.Begins a Solver solution run.

To invest in each of 4 stocks plus T-bills Of employees on each of 7 weekly schedules The objective cell, constraint cells, and decision variableĬells for each Solver model are already specified: Routes, Staff Scheduling, Maximizing Income, Portfolio of Securities,Īnd Engineering Design- open the workbook, switch to the worksheet To use any of the six worksheets- Product Mix, Shipping That demonstrates the types of problems you can solve.Ĭan use the sample worksheets in Solvsamp.xls to help you set up your Solver runs, the new values are as follows.Įxcel includes a workbook, Solvsamp.xls in the Office\Samples folder, Quarter, so the values are related to the formula in the target cell The decision variable cells are used to calculate the profit for each The total profit reaches the maximum possible amount. Total budget constraint of $40,000 (cell F11), until the value for Solver canĬhange the quarterly budgets for advertising (cells B11:E11), up to a Of sales revenue, the associated expenses, and the profit. The following example, the level of advertising in each quarterĪffects the number of units sold, indirectly determining the amount
Projected advertising budget and see the effect on your projected For example, you can change the amount of your Solver to determine the maximum or minimum value of one cell byĬhanging other cells. Programming and nonlinear optimization to genetic and evolutionary Solver uses a variety of methods, from linear The final values found by Solver are a solutionįor this model. Objective, constraint and decision variable cells and the formulas The result you want for the objective cell. Variable cells to satisfy the limits on constraint cells and produce Solver adjusts the values in the decision Solver works with a group of cells - called decisionĬells - that participate in computing the formulas in the objectiveĪnd constraint cells. Or limits, on the values of other formula cells on a worksheet. Value for a formula in one cell - called the objective With Solver, you can find an optimal (maximum or minimum) Is part of a suite of commands sometimes called what-if analysis
