Now, back to the example function problem given in step 2: y = 2x^2 + 3x – 4. If a scenario in which the production manager of a firm would presumably want to maximize the profitability of the Product during each month, the target cell would be used. The target cell will represent the objective or goal. With Solver, you can find an optimal values or solutions for a formula in one cell. The guess selection is not particularly useful for our purposes and will not be discussed here.
Options brings up the Solver options dialogue box. Reset all clears the current problem and resets all parameters to their default values. Change allows you to modify a constraint already entered and delete allows you to delete a previously entered constraint. Finally, the constraints must be specified in the Subject to the Constraints box by clicking on Add. The Cells box should contain the location of the decision variables for the problem. If value is selected, the Solver will attempt to find a value of the target Cell equal to whatever value is placed in the box just to the right of this selection. Max or min may be selected for finding the maximum or minimum of the set target cell. The Set Target Cell box should contain the cell location of the objective function for the problem under consideration. These parameters will vary depending upon your problem. Once here, you will need to specify the parameters in order to run the solver. Once you click the Solver option, the Solver Parameters dialogue box will appear. The goal is to have cell B1 vary the value of x until the cell B2 (the function) is 0. Cell B1 plays the part of x in the formula, and by changing the values in cell B1, you will notice that the results of the function will change. Define the function in cell B2 by typing f(x)= in cell A2 and typing =2*B1^2+3*B1-4 in cell B2. Assign the variable x to the cell B1 by typing x= in cell A1 and typing nothing in cell B1. The second step is to assign the variable of the function to one specific cell. In the following illustration, the first step of all excel solutions is to properly define the function that is being solved. 2x^2 + 3x -4 = 0, as anyone would normally do by hand. Solver will solve the equation for 0, i.e. A simple function is given below as an example problem where someone would wish to find the root of the function. Solver is equipped with functions that allow users to find the root/solution of an equation. Now lets open up Excel and get started!Įxcel Solver is used by engineers and mathematicians to solve a large variety of mathematical equations and systems. Solver adjusts the values in the decision variable cells to satisfy the limits on constraint cells and produce the result you want for the objective cell. Solver works with a group of cells also called decision variable cells, that participate in figuring out the formulas in the objective and constraint cells. This is called the objective cell, which is subject to constraints, or limits, on the values of other formula cells on a worksheet. With Solver, you can find an optimal (maximum or minimum) value for a formula in one cell. It solves complex linear and non linear problems. The Solver is an add-in for Microsoft Excel which is used for the optimization and simulation of business and engineering models. In Microsoft Excel, Solver is part of a category of commands called what-if analysis tools.

This guide will cover all parts of the solver tool function and a step-by-step guide on how to use it. We will specifically be focusing on the solver tool aspect of the program and how users can use it to their advantage.
The purpose of this guide is to introduce people to the computer program Microsoft Excel.
