Decision Variable Cells: In this section, we can identify the optimal solution (the values in the column labeled Final Value), the coefficients or parameters in the objective function (the values in the Objective Coefficient column), the allowable increase and the allowable decrease for each of the individual coefficients in the objective function, which allows us to guarantee that the current optimal solution is maintained.įor example, let’s consider the coefficient c 1 = 34 associated with the variable of decision x 1 in the maximization of the objective function.Objective Cell (Max): The optimal value, which is to say, the value reached when evaluating the optimal solution in the objective function, is 342.In the following section, we will go over how to interpret each of the three parts that the Sensitivity Report gives us to solve. For the example proposed in this article, we get the following results: Once we request the Sensitivity Report, a new page will be generated in the Excel file in which we are working, with a report on the results. In the following, we can obtain the Sensitivity Report by clicking on the module Reports > Optimization > Sensitivity, which will show us the following:
In the following, we present a simple model of Linear Programming, which will be computationally implemented, giving us the Sensitivity Report that we will then analyze in detail, in order to interpret it in the correct manner.īy using Premium Solver Pro to solve the previous model, we reach the optimal solution X 1 = 3 and X 2 = 6, with an optimal value V(LP) = 342. In this context, the sensitivity or post optimal analysis seeks to analyze the impact that a modification of one or several parameters has on the results of a model.Ī Premium Solver Pro Sensitivity Report is divided into 3 parts: In this sense, students can quickly acquire the necessary skills to deal with different size optimization problems in a platform known, as it turned out.įurthermore, it is worth noting that Premium Solver Pro not only allows us to solve optimization models, but also offers the opportunity to create Sensitivity Reports once we have reached the optimal solution and optimal value of the base model. In my experience as an Operations Research professor, I have personally verified the benefits of computationally implementing optimization models of varying complexity in an intuitive and reliable learning environment. Using a professional optimization tool like Premium Solver Pro offers multiple benefits that are quickly identified by those starting to learn about the fascinating world of Operations Research.
