This is very needed in modern times when many companies struggle to use their resources in the most efficient way. The Solver will calculate the proper order between cities. The Salesman needs to visit each city only once before going back home. The clue to the Multiple Traveling Salesman Problem is to find the shortest possible path for deliveries to many places. The Solver tool is so powerful that it will find the result in less than a minute. This is a well-known mathematical problem to solve, which requires complicated and time consuming calculations. Let's calculate the Multiple Travelling Problem. Solving the Multiple Traveling Salesman Problem using Solver You can now use the saved data to manage your expenses and income until you approach breakeven for the loan collected. When this is done, input the necessary figures and make use of the Autosum features. We also need to determine the lowest and highest amount that can be charged per hour for the cybercafé as determined by the research from other cybercafés. You can't have 2.4 computers because it will be difficult to analyze the data. It is important to make sure that the number of computers is a whole number. Determine the constraints, like the minimum and maximum hours of work and the minimum and maximum numbers of computers. The final step is to determine the cells that will affect the target cell. If you want, you can equally set the value to be zero (0), which will allow you to establish the break even point where the monthly earnings will be equal to the monthly expenditures. If we are dealing with the minimization of cost here, then the maximum and minimum options will be useful. You may decide to set the lowest or highest value, but we won't need to set this level in this example. When the new window appears, select the target cell and equate its value to a certain number, like 70,000 or 100,000. Using the Solver and an analysis of the per hour rates obtainable in other cybercafés, a what-if-analysis can be done to determine what can be charged to customers. The estimates will be made for break even (because we want to repay the bank loan before looking at profits). But at this point, we are not going to concern ourselves with profit. The rented accommodation can take up to 24 computers, but let's begin with 12.īased on the cost, the minimum amount to charge the customers can be determined. The regular monthly expenses include maintenance, electricity, salaries, internet charges to the ISP, rent, advertisement costs, and telephone costs. We can make use of the PMT function to find the number of monthly installments needed to completely repay the bank. Suppose you take a bank loan to purchase UPS, furniture, computers, and other accessories needed to successfully run a cybercafé. The following steps will help solve this problem using Solver. Let's say you want to use this tool to help you solve a business problem, such as running a cybercafé.
#How to install excel solver how to#
Okay, now that we are through adding Solver to the Excel features, it is time to learn how to use the Solver tool in Excel. But the most common types of parameters are constraints, changing cells, and target cells. The parameters you specify will depend on the type of problem you want to solve. The Solver can be located on the Data tab under the Analysis field.Īfter opening the Solver, a dialog box loads automatically, which allows you to specify the parameters with which you want to run the Solver. The Solver has just been installed and added to your Excel. Under the Add-Ins option, click on the Solver and then click on the Go button.Ī new dialog window appears. To install the Solver tool, click the Options on the green File tab. If you don't see it, then Solver may not be installed. The Solver is displayed on the right side under the Analysis. Install, Start-up the Solver Add-in and follow the process.īefore you begin, ensure that the Solver is already installed on your computer. This article will provide a step-by-step guide on how to use Solver to find a solution to a business problem.īelow is a practical example of the use of Solver to find solutions to all kinds of decision problems. Constraints can also be applied to minimize the value that can be used by Solver. You can use a solver to ascertain an optimal value in one cell known as the "target cell".īasically, a solver is used for a group of cells that are directly or indirectly related. The solver in Excel is part of an analysis tool known as " What-If analysis".
