The value of the Lagrange multiplier is a measure of the sensitivity of the constrained objective to changes in the constrained variables. The sensitivity report shows the names, corresponding cells and final values of the variable cells and constraints. Output: Sensitivity Report How to interpret a sensitivity report ? This is how a Sensitivity Report is presented:įigure 8. The Sensitivity Report will be generated in another worksheet named Sensitivity Report 1. The optimal solution will then reflect in cells C3 to C5 in our worksheet (Sheet 1 below).

The time it takes for Solver to complete the calculations might vary depending on the complexity of the problem.

Sensitivity Report option in Solver Results Tick Keep Solver Solution and under Reports, select Sensitivity. The Solver Results dialog box will appear.Enter the following information needed by Solver as shown below:.The Solver Parameters dialog box will appear. We must first use the Excel Solver Analysis and after we have performed the calculation, we can then generate the sensitivity report. The available stock for reagent B is only 5 liters.The volume of the whole mixture must still be equal to 110 liters.Our goal is to obtain a mixture concentration of 10% by determining the required volume of the reagents, with the concentration of each reagent remaining constant. Which can be interpreted as the sum of volume of the pure chemicals divided by the volume of the whole mixture.įigure 3. The concentration of the mixture is given by the formula Suppose we want to prepare a mixture in a laboratory, using water and two chemical reagents A and B. Solver command button in Data tab Prepare our data Goal Seek can be accessed through the Data tab > Solver buttonįigure 2. Final result: Sensitivity Report Where is Excel Solver? Solver is a What-if-Analysis tool that solves for an optimal value in the target cell by changing the values in the variable cells.įigure 1. Solver, like Goal Seek, is very useful in various fields of study and application. Sensitivity reports can be generated after using the Excel Solver add-in.
