I have also set constraints within the solver to cap each task to the allotted time allowed per task. Below you can find the optimal solution and the sensitivity report. The process stopped with no further improvement after one additional switch of departments 6 and 7. Excel provides some useful Data Analysis tools to achieve this. We can estimate the optimal values of these critical factors to optimize the process.

It enables the identification of critical process factors based on data rather than impressions. Linear Programming Using Excel Solver - Free download as Powerpoint. Before you click OK, select Sensitivity from the Reports section. Design of Experiments (DOE) is a powerful methodology for process improvement. After the solver found a solution, you can create a sensitivity report. I have set it up so that the sums of the tasks will take away from the available time left when changed by the solver. Sensitivity analysis gives you insight in how the optimal solution changes when you change the coefficients of the model. The goal is to maximize the profit of these three firms. All three firms have a maximum allotted time of 1200 minutes to mill, 900 to inspect, and 1440 to drill. After each firm completes all of these tasks they will earn a certain amount of profit, Alpha will earn $2.40, Bravo will earn $2.50, and Charlie will earn $3.00. Charlie requires 8 to mill, 4 to inspect, and 16 to drill. The Excel Solver is used to find solutions. In the theme to the Constraints box, put in any restraints that you aspire to apply. The Math Programming add-in is called to setup the LP and IP models necessary for capacity planning. Associated Add-in s - Click the add-in name to transfer to the add-in page. Bravo requires 10 minutes to mill, 4 to inspect, and 8 to drill. Add-in - Click the add-in name to download a zipped. Alpha requires 12 minutes to mill, 5 minutes to inspect and 10 minutes to drill. They each require different amounts of minutes to complete each task. They each complete three tasks: Milling, Inspecting, Drilling. Design and Use of the Microsoft Excel Solver Daniel Fylstra Frontline Systems Inc.
Read the general instructions before attempting to use an add-in.

Simply double clicking on the add-in file does not install it. They must be installed rather than opened. I have three firms: alpha, Bravo, Charlie. Add-ins hold macros that automate most of the features of model building and model solving. I have set up an optimization problem but i must be doing something wrong and I could use your help.
