SOLVER

• Solver is an add-in application that manipulates variables based on constraints to find the optimal solution to a problem.

• Solver is one of the most sophisticated what-if analysis tools, and people use Solver in a variety of situations and industries.

3

OBJECTIVE AND VARIABLE CELL

• The objective cell is the cell that contains the formula-based value that you want to maximize, minimize, or set to a value in Solver.

• A changing variable cell is a cell containing a variable whose value changes until Solver optimizes the value in the objective cell.

4

LOAD SOLVER ADD-IN

• Files -> Options -> Add Ins• Manage add-in -> Excel add-in -> Go• Select solver add-in -> Ok

5

SET OBJECTIVE AND VARIABLE CELL

• Data -> Solver• Set objective variable cell and value• Set changing variable cells• Close and save the workbook.• Add constraints.

6

SOLVE

• Chose a solving method:– GRG Nonlinear: guaranteed local optimal– Simplex LP: guaranteed global optimal, must

be linear– Evolutionary: good solutions for non smooth

functions• Solve

7

CHAPTER 9 AND 10

• Multiple Worksheets– Group– Fill across worksheets– Enter and format data

8

HYPERLINK

• Enter data in cell• Insert -> hyperlink• Select link and range of data

9

3D FORMULAS

• A 3-D formula is a formula or function that refers to the same range in multiple worksheets.– 'Worksheet Name'!RangeOfCells=SUM('FirstWorksheet:LastWorksheet'!RangeOfCells)
