Maximum Labor Hours (LH) available are 10,000 hours.Maximum quantity of Raw Material (RM) is 5,000 units.Numerical details of the above problem is: In other words, how much quantity of each product line it should produce so that the profit it earns is maximum. Now, it has to decide which product line (Men’s, Women’s Children’s clothing) will generate maximum profit. The problem it faces is that it has a limited quantity of raw material and labor hours. Now, In order to understand how solver add-in works, let’s solve a product-mix example with two constraints: Solver Add-In (Product Mix) Example:Ī garments factory (which produces a clothing line for men, women, and children) wants to maximize its profits. Note: What all these solving methods mean is currently out of the scope of this article and I will discuss them later in some other article. Evolutionary problem is used for non-smooth problems.GRG Non-Linear problem is used for non-linear problems.Simplex LP method is used for linear problems.Which method to choose depends on the nature of the problem that we are facing. Solving Method: MS-Excel provides three ways to solve a particular problem.Constraints: Constraints are the limiting factors which restrict us to achieve certain objectives.A Variable is the element of the data which is changed in order to achieve our objective functions. Variable Cell: Cell which contains variables.

Objective Function: This is your target that you’re trying to achieve.Scenario Manager: is a window where you input all your decision variables.Must-Know Terminologies to Use the Excel Solver Add-in Once the Solver add-in is up and live, let’s now first get acquainted with the terminologies that will come in handy to use this add-in effectively. In the “Analysis” group, you will see a new option of “Solver” which means that the add-in is now active. To confirm that the Solver Add-in active click “Data” in the menu bar.Click “Ok” button to confirm your action. Search for the solver add-in and checkmark the option to activate it. A small pop up window will show the Add-ins available in your version of excel.In “Excel Options” window, click “Add-Ins” and then select “Excel Add-ins” in the “Manage” field right at the bottom and click “Go”.Within an excel worksheet and from the menu bar, go to “File” and then click “Options”.So in order to activate Solver in Excel 2013, follow the below steps: However, the process of adding it is more or less the same in other versions of excel as well.Įxcel already has Solver Add-in within itself.

#How to use excel solver function to fit a constituve model how to#
Since I use Excel 2013, I will tell you how to get solver on excel 2013. So any excel’s version from 97 and beyond (including Excel 2016) will have this tool. The Solver Add-in is available since the 97-2003 versions of Microsoft Excel. Which Versions of Excel Provide the Solver Add-In? In short, I will mention all the necessary details to get you up and running with the excel solver add-in. Besides, we will also discuss how you can add solver add-in in excel, which excel versions provide this add-in, how to define your parameters e.t.c. In this article, I will discuss in detail how you can use the Excel Solver Add-In to perform a variable analysis and find the optimal solution. In Excel Solver Add-In, all you have to do is define your data, set objective functions, identify constraints in the scenario manager and then let excel take care of the rest.

Once everything is set, use the trial and error method to identify an optimal solution.Ĭhange just one variable and your whole model starts showing a totally different picture. The major reason is that you have to take care and keep track of the numbers of decision variables, identify the constraints, make sure that your resources do not exceed those constraints. If you are familiar with applying different values to a particular scenario in order to figure out the optimum or the closest result depicting the actual results, you must appreciate the complexity this whole process brings. Today, we are going to focus on the Excel solver add-in though. If working with a large data set, some also consider adding the Excel plugin for conjoint analysis to cross-reference data to further optimize their workflow. It helps in simplifying the whole process of identifying the optimal solution to a problem, something that could take considerable time and painstaking effort, to something solved within a few clicks. Microsoft Excel Solver add-in is a great tool to perform complicated “What-If” analysis within no time.
