In addition, the profit for each pallet of panels is entered in cells B5, C5, D5, and E5, which allows the total profit, objective, to be calculated in cell F5: In Figure 1, the Excel worksheet cells B4, C4, D4, and E4 are reserved for the decision variables, T, P, S and A representing the number of pallets of each type of panel to produce. Where: T – Tahoe P – Pacific S – Savannah A – Aspen. Profit (Maximize) => 450 T + 1150 P + 800 S + 400 AĬonstraints – Maximizing the profit is subject to:ĥ0T + 50P + 100S + 50A = 0 (i.e., products built cannot be negative) Given the profit per pallet and available resources for the production cycle to be optimized, the formulas for the total profit to be maximized and the constraints associated with the available resources can be written as follows: For the given production cycle, the available resources and target profit from each paneling are provided. As can be seen in the table, each type of paneling is made by gluing and pressing together a different mixture of pine and oak chips. Generalized Reduced Gradient (GRG) Nonlinear algorithm is used for smooth nonlinear problems in which at least one of the constraints is a smooth nonlinear function of the decision variables.īased on the tutorial in Solver (n.d.-e), Table 1 shows data used for product mix optimization for maximizing the profit of a factory that produces four different types of wood paneling. GRG Nonlinear method (Solver, n.d.-d).Since it is difficult to determine the direction in which a function is increasing or decreasing, in such non-smooth problems, they are the most difficult type of optimization problems to solve. Evolutionary method (Solver, n.d.-c): This algorithm is used for non-smooth problems in which some of the functions are non-smooth or discontinuous.The Simplex Linear Programming (LP) algorithm is used for solving Linear Programming problems – mathematical models whose requirements are characterized by linear relationships, which consist of a single objective represented by a linear equation that must be maximized or minimized. Depending on the type of problem to be optimized, there are three different types of optimization algorithms or methods that are supported in the Excel Solver add-in: According to Solver (n.d.-e), the “best” or optimal solution might mean maximizing profits, minimizing costs, or achieving the best possible quality.Īccording to Solver (n.d.-a), analytic solver for excel has capabilities such as Data/text mining conventional optimization Monte Carlo Simulation and stochastic and robust optimization.
#Excel analytic solver platform software#
The solver is an Excel add-in software that helps users determine the best way to optimize resources where multiple decisions need to be made in the best possible way while simultaneously satisfying a number of logical conditions (or constraints).

This article will, therefore, outline the use of an Excel add-in, Solver, to optimize data after a manual preparation of an Excel data model and, explain the role of Data Mining in solving optimization problems in large data sets.

In this regard, Data Mining could play a role in identifying data inconsistency patterns, during the data preparation phase, and enable to fix the issues and increase the quality of the data.

When the size of data is big, in the case of big data, it would become very difficult for a domain expert to fix such quality issues. To extract useful information from data, data preparation deals with quality issues and would require a piece of domain knowledge to fix some of the inconsistencies in the data. However, the quality of data being collected is less of a concern, upfront, when the infrastructure to collect the data is put in place. The advent of personal devices and IoT sensors, that are capable of generating data, coupled with the need for extracting information from data has fueled the speed, frequency, and volume of data being collected by organizations.
