## Using Solver to determine the optimal product mix

## How can I determine the monthly product mix that maximizes profitability?

Product mix can’t use more resources than are available.

In a similar fashion, our profit is determined by

Profit is easily computed in cell D12 with the formula SUMPRODUCT(D9:I9,$D$2:$I$2) .

We now can identify the three components of our product mix Solver model.

Target cell. Our goal is to maximize profit (computed in cell D12).

Changing cells. The number of pounds produced of each product (listed in the cell range D2:I2)

Constraints. We have the following constraints:

We can’t produce a negative amount of any drug.

To begin, click the Data tab, and in the Analysis group, click Solver.

The Solver Parameters dialog box will appear, as shown in Figure 27-2.

D2<=D8 (the amount produced of Drug 1 is less than or equal to the demand for Drug 1)

E2<=E8 (the amount of produced of Drug 2 is less than or equal to the demand for Drug 2)

F2<=F8 (the amount produced of Drug 3 made is less than or equal to the demand for Drug 3)

G2<=G8 (the amount produced of Drug 4 made is less than or equal to the demand for Drug 4)

H2<=H8 (the amount produced of Drug 5 made is less than or equal to the demand for Drug 5)

I2<=I8 (the amount produced of Drug 6 made is less than or equal to the demand for Drug 6)

Click OK in the Add Constraint dialog box. The Solver window should look like Figure 27-7.

The target cell is computed by adding together the terms of the form (changing cell)*(constant) .

Why is this Solver problem linear? Our target cell (profit) is computed as

Our demand constraints take the form

Having shown that our product mix model is a linear model, why should we care?

We produce more of Drug 5 than the demand for it.

We use more labor than what is available.

We use more raw material than what is available.

## Does a Solver model always have a solution?

## What does is mean if a Solver model yields the result Set Values Do Not Converge?

Resolve our drug example assuming that a minimum demand of 200 units for each drug must be met.

## How to solve optimization problems with Excel and Solver

In Excel, optimization problems are solved using an Add-In that ships with Excel called Solver.

On Mac, Solver is added by going to Tools then Add-ins and selecting Solver.xlam from the menu.

A Solver button will appear in the Analysis section of the Data tab in every version.

## Solving Dynamical Optimization Problems in Excel

= Initial solution value – Target Value

- If your initial solution is a single value (e.g., an integral evaluation) you can reference it directly in your constraint formulas.
- On the other hand, if your initial solution is an array result (e.g., ODE or PDE solution), you can still define arbitrary formula constraints on a single or a range of values in the result array. The only requirement is that when referencing any value or range of values in the initial solution result in your constraint formulas you must do so using the auxiliary function DYNVAL . DYNVAL is a dummy function that simply returns the value of its argument but in this context, it ensures that its argument is dynamically evaluated during the optimization.

- If you do not have a cost formula to maximize or minimize, use NLSOLVE to solve the system of constraints formulas for the unknown model parameters.
- On the other hand, if you do have a cost formula, then use Excel Solver to setup an optimization problem to minimize or maximize your cost formula subject to the constraint formulas you have defined.

Rmember the Steps to solve an LP Problem

- Understand the problem. The goal of a linear programming problems is to find a way to get the most, or least, of some quantity — often profit or expenses. This quantity is called your objective function . The answer should depend on how much of some decision variables you choose. Your options for how much will be limited by constraints stated in the problem.
- Describe the objective. What are you trying to optimize? Are you trying to minimize costs? Maximize production quantities? You may have constraints like “you can’t spend more than $1000” or “you mus’t ship at least 50 tons of product C”. These are limits but don’t necessarily reflect your employer’s top priorities; don’t mistake these for suggestions that you minimize costs or maximize production.
- Define the decision variables. The answer to a linear programming problem is always “how much” of some things. What are those things? Choose variables to represent how much of each of those things.
- Write the objective function. Use the variables you just chose to write down an algebraic expression that describes the amount you’re trying to minimize.
- Describe the constraints. What are the limits on “how much” your decision variables can be? Look for words like “at least”, “no more than”, “two thirds of”, “we must fill orders for”, etc.
- Write the constraints in terms of the decision variables. For each constraint such as “at least $500” or “no more than 29” write an inequality using the decision variables.
- Add the nonnegativity constraints. Don’t forget to include non-negativity constraints like P >= 0. These are worth a quick two points on the quiz.
- Set up the Problem in Excel.
- Use Solver to find a solution.

Solver is a Microsoft Excel add-in program you can use for optimization in what-if analysis.

You can use Solver to find optimal solutions for diverse problems such as −

Determining the monthly product mix for a drug manufacturing unit that maximizes the profitability.

Scheduling workforce in an organization.

Solving transportation problems.

Financial planning and budgeting.

## Activating Solver Add-in

In case you do not find the Solver command, activate it as follows −

- Click the FILE tab.
- Click Options in the left pane. Excel Options dialog box appears.
- Click Add-Ins in the left pane.
- Select Excel Add-Ins in the Manage box and click Go.

## Solving Methods used by Solver

Used for linear problems. A Solver model is linear under the following conditions −

The target cell is computed by adding together the terms of the (changing cell)*(constant) form.

## Generalized Reduced Gradient (GRG) Nonlinear

## Evolutionary

Understanding solver evaluation.

The Solver requires the following parameters −

Solver evaluation is based on the following −

The values in the decision variable cells are restricted by the values in the constraint cells.

Solver uses the chosen Solving Method to result in the optimal value in the objective cell.

## Defining a Problem

- The number of units sold, indirectly determining the amount of sales revenue.
- The associated expenses, and
- The profit.

You can proceed to define the problem as −

Next, set the cells for the required calculations as given below.

No. of units available for sale in Quarter1 is 400 and in Quarter2 is 600 (cells – C7 and D7).

The initial values for advertising budget are set as 10000 per Quarter (Cells – C8 and D8).

Revenue is calculated as Unit Price * No. of Units sold (Cells – C10 and D10).

Profit is Revenue – Expenses (Cells C12 and D12).

Total Profit is Profit in Quarter1 + Profit in Quarter2 (Cell – D3).

Next, you can set the parameters for Solver as given below −

As you can observe, the parameters for Solver are −

Objective cell is D3 that contains Total Profit, which you want to maximize.

There are three Constraint cells - C14, C15 and C16.

Cell C14 that contains total budget is to set the constraint of 20000 (cell D14).

## Solving the Problem

The next step is to use Solver to find the solution as follows −

Step 1 − Go to DATA > Analysis > Solver on the Ribbon. The Solver Parameters dialog box appears.

Step 2 − In the Set Objective box, select the cell D3.

Step 4 − Select range C8:D8 in the By Changing Variable Cells box.

Step 5 − Next, click the Add button to add the three constraints that you have identified.

Step 7 − Set the constraint for total no. of units sold in Quarter1 as given below and click Add.

Step 8 − Set the constraint for total no. of units sold in Quarter2 as given below and click OK.

Step 9 − In the Select a Solving Method box, select Simplex LP.

The results will appear in your worksheet.

## Stepping through Solver Trial Solutions

You can step through the Solver trial solutions, looking at the iteration results.

Step 1 − Click the Options button in the Solver Parameters dialog box.

The Options dialog box appears.

Step 2 − Select the Show Iteration Results box and click OK.

## How to use Solver in Excel with examples

## What is Excel Solver?

## How to add Solver to Excel

To add Solver to your Excel, perform the following steps:

## Where is Solver in Excel?

## Where is Solver in Excel 2003?

Now that you know where to find Solver in Excel, open a new worksheet and let's get started!

## How to use Solver in Excel

And now, let's see how Excel Solver can find a solution for this problem.

## 1. Run Excel Solver

The Solver Parameters window will open where you have to set up the 3 primary components:

## Variable cells

In this example, we have a couple of cells whose values can be changed:

- Projected clients per month (B4) that should be less than or equal to 50; and
- Cost per service (B5) that we want Excel Solver to calculate.

To add a constraint(s), do the following:

- In the Constraint window, enter a constraint.
- Click the Add button to add the constraint to the list.

- Continue entering other constraints.
- After you have entered the final constraint, click OK to return to the main Solver Parameters window.

- Less than or equal to , equal to , and greater than or equal to . You set these relationships by selecting a cell in the Cell Reference box, choosing one of the following signs: <= , =, or >= , and then typing a number, cell reference / cell name, or formula in the Constraint box (please see the above screenshot).
- Integer . If the referenced cell must be an integer, select int , and the word integer will appear in the Constraint box.
- Different values . If each cell in the referenced range must contain a different value, select dif , and the word AllDifferent will appear in the Constraint box.
- Binary . If you want to limit a referenced cell either to 0 or 1, select bin , and the word binary will appear in the Constraint box.

To edit or delete an existing constraint do the following:

- In the Solver Parameters dialog box, click the constraint.
- To modify the selected constraint, click Change and make the changes you want.
- To delete the constraint, click the Delete button.

In this example, the constraints are:

- B3=40000 - cost of the new equipment is $40,000.
- B4<=50 - the number of projected patients per month in under 50.

## 3. Solve the problem

The Solver Result window will close and the solution will appear on the worksheet right away.

- If the Excel Solver has been processing a certain problem for too long, you can interrupt the process by pressing the Esc key. Excel will recalculate the worksheet with the last values found for the Variable cells.
- To get more details about the solved problem, click a report type in the Reports box, and then click OK . The report will be created on a new worksheet:

## Excel Solver examples

## Excel Solver example 1 (magic square)

With all the formulas in place, run Solver and set up the following parameters:

- Set Objective . In this example, we don't need to set any objective, so leave this box empty.
- Variable Cells . We want to populate numbers in cells B2 to D4, so select the range B2:D4.
- $B$2:$D$4 = AllDifferent - all of the Variable cells should contain different values.
- $B$2:$D$4 = integer - all of the Variable cells should be integers.
- $B$5:$D$5 = 15 - the sum of values in each column should equal 15.
- $E$2:$E$4 = 15 - the sum of values in each row should equal 15.
- $B$7:$B$8 = 15 - the sum of both diagonals should equal 15.

## Excel Solver example 2 (linear programming problem)

## Source data

## Formulating the model

To define our linear programming problem for the Excel Solver, let's answer the 3 main questions:

- What decisions are to be made? We want to calculate the optimal quantity of goods to deliver to each customer from each warehouse. These are Variable cells (B7:E8).
- What are the constraints? The supplies available at each warehouse (I7:I8) cannot be exceeded, and the quantity ordered by each customer (B10:E10) should be delivered. These are Constrained cells .
- What is the goal? The minimal total cost of shipping. And this is our Objective cell (C12).

The last thing left for you to do is configure the Excel Solver parameters:

- Objective: Shipping_cost set to Min
- Variable cells: Products_shipped
- Constraints: Total_received = Ordered and Total_shipped <= Available

## How to save and load Excel Solver scenarios

## Saving the model

To save the Excel Solver scenario, perform the following steps:

## Loading the saved model

When you decide to restore the saved scenario, do the following:

## Excel Solver algorithms

- GRG Nonlinear. Generalized Reduced Gradient Nonlinear algorithm is used for problems that are smooth nonlinear, i.e. in which at least one of the constraints is a smooth nonlinear function of the decision variables. More details can be found here .
- LP Simplex . The Simplex LP Solving method is based the Simplex algorithm created by an American mathematical scientist George Dantzig. It is used for solving so called Linear Programming problems - mathematical models whose requirements are characterized by linear relationships, i.e. consist of a single objective represented by a linear equation that must be maximized or minimized. For more information, please check out this page .
- Evolutionary . It is used for non-smooth problems, which are the most difficult type of optimization problems to solve because some of the functions are non-smooth or even discontinuous, and therefore it's difficult to determine the direction in which a function is increasing or decreasing. For more information, please see this page .

Hi everyone, i am Silvana Pantic, from Slovenia, am so glade coming back to this great forum to testify about the help i received from Credit-Suisse Loan Film. I was in desperate need of a loan in other to be free from debt and financial bondage that was place on me by my ex husband. It was really bad that i have to seek for help from Friends,family and even my bank but on one could assist me because my credit score was really bad. So i was browsing with my computer and saw some testimonies from people that Credit-Suisse Loan Film assisted with a loan, then i decided to contact them via email {[email protected]}

Hello there!

I have a problem with production scheduling. We have three wire cutting machines and 90 different tools for contactor crimping and seal application (automotive harness business) that are being used on these machines as active processing parts for the different wires and other harness components. Operation on each of the machine is similar except that combination of tools is different, first the machine unroll the wire form the spool, then it cuts the wire on a predetermined length, then applies a seal (water protection) and then crimp a contactor. There are operations where we use two seal applicators and crimping tools on a single machine, so both ends of the wire are sealed and crimped. The combination depends on the wire cross-section, seal specification and contactor specification (crimp parameters vary based on the client specification). Goal - is to prepare the production plan with minimum change over of the tools and eliminate the situations when the tools are needed on more than one machine. The replanting has to be flexible, even daily. Some tools are available in more than one unit (two three). The changeover of applicators is longer than for crimping tools (1.5 hours vs. 30 min). Would be good to have a tip how to solve this complex task.

Look forward to hear from you! Slava

I tried the Magic Square one with my students and we were not able to solve it as directed. We received error messages, such as "An AllDifferent Constraint must have either no bounds, or a lower bound of 1 and and upper bound of N, where N is the number of cells in the Constraint." However, we could not figure out where to set this parameter. Can anyone help with this?

Hi Michelle, To figure out the source of the problem, you can download our sample workbook and compare our Magic Square model with yours.

Hi. I’m very new to solver and was asked to solve this question: Mathew is the business owner of a laundry shop located at City Plaza. He has operated the business since June 2018 and after operating it for 6 months, he has realised that in certain months, the sales revenue is sufficient to cover the operating expenditures, while for certain months the sales revenue is not enough to cover the operating expenditures and he has to rely on his personal savings to tide through. It is now the last week of December 2018 and he realises that moving forward, it is better for his business to have access to loan facility from the bank to ease out his operation. However, he is unsure of which loan package to sign up and has approached you, a close friend, to help him as you are trained in financial planning. To perform the analysis, you have requested Mathew to give a projection of the sales revenue and operating expenditures for the next twelve months. The estimates are as follows: Month Sales Revenue ($) Bills ($) January 4,000 6,000 February 3,000 5,000 March 3,000 4,000 April 3,000 3,000 May 5,000 4,000 June 9,000 1,000 July 3,000 6,000 August 2,000 6,000 September 1,000 4,000 October 2,000 2,000 November 6,000 1,000 December 10,000 1,000 Based on the whole year projection, Mathew will make $8,000 net profit at the end of the year. However, since all expenditures must be paid in full by the end of every month, Mathew may be short on cash in some months until he sees the big sales in certain months, e.g. June and December. Mathew has two sources of loan: Annual loan at 12% of interest per year, e.g. he borrows $100 at the beginning of January 2019 and pays back $112 at the end of December 2019. Early-pay-back is not allowed and Mathew can get an annual loan in January only. Monthly loan at 2.5% of interest, e.g. he borrows $100 at the end of March and pays back $102.5 at the end of April. Early-pay-back is not allowed and Mathew cannot get a monthly loan in December. He needs your help to determine whether he should just take up the annual loan with effect from January, or a mixture of both types of loan facilities. Assume that Mathew has zero cash balance at the beginning of 2019.

I have tried to look up similar questions online but the prob is I don’t understand how the solution was derived. Can someone help please? Thank you.

Dear Cheusheva I have tried my best to study your instruction and practice with my problem but I fail to come to an acceptable result. I hope you help me. I have a table as follows x1 x2 x3 x4 Age Code Name 34 36 38 42 17 0 A 32 38 40 41 19 1 B 36 39 32 40 20 0 C 42 34 42 41 19 1 D 33 38 42 29 20 1 E 31 39 41 45 18 0 F (others in similar form) I want to have a minimum of sum of four variables with the constraints - A person (name) is chosen only 1 time in the sum (4 people for four variables) - Sum of code is 2 (two "1" and two "0") - sum of age is <=60 I hope to have your reply soon. Best regards

You explain very well! You have a gift

Fantastic Examples to make you understand the algorithm.

Great. Everything that I wanted to know more about solver is here.

Question? I created a workbook for scheduling hours for employees working at a movie theater for 1 week. I need to have a certain number of employees for each day of the week, but I need to deal with their timeoff requests. And some of my employees are fulltime and some parttime. The timeoff request says "Can't work Saturday". I need to write a constraint based on those entries, add constraints so that employees are not scheduled to work on days when they are unavailable to work. How do I write a constraint to cover this?

Excellent Sir, thanks a lot.

i faced a problem with exelsolver by error how can i correct that?

hello, please i was giving this assignment but i am finding it hard to understand it. please can any one help me solve it?

To create a Linear Programming model using MS Excel Solver (25%) A metal works manufacturing company produces four products fabricated from sheet metal in a production line that consist of four operations: 1) Stamping, 2) Assembly, 3) Finishing and 4) Packaging. The processing times per unit for each operation and total available hours per month are as follows:

Product (hour/unit) Operation 1 2 3 4 Total Hours available per month Stamping 0.07 0.2 0.1 0.15 700 Assembly 0.15 0.18 -- 0.12 450 Finishing 0.08 0.21 0.06 0.10 600 Packaging 0.12 0.15 0.08 0.12 500 5 The sheet metal required for each product, the maximum demand per month, the minimum required contracted production, and the profit per product are given as follows: Monthly sales demand Product Sheet Metal (ft2 ) Minimum Maximum Profit(£) 1 2.1 300 3,000 9 2 1.5 200 1,400 10 3 2.8 400 4,200 8 4 3.1 300 1,800 12 The company has 5,200 square feet of fabricated metal available each month. Formulate a linear programming model and use Excel Solver function to suggest the best mix of products which would result in the highest profit within the given constraints.

## Optimization Tutorial

Welcome to our tutorial about Solvers for Excel and Visual Basic -- the easiest way to solve optimization problems -- from Frontline Systems, developers of the Solver in Microsoft Excel.

This tutorial addresses the following questions:

## What are Solvers Good For?

- What Must I Do to Use a Solver?
- How Do I Define a Model?
- Can You Show Me Step by Step?
- What Kind of Solution Can I Expect?
- What Makes a Model Hard to Solve?

After completing this tutorial, you can learn even more about topics such as linearity versus nonlinearity and sparsity in optimization models by completing our Advanced Tutorial .

Solvers, or optimizers, are software tools that help users determine the best way to do something. The "something" might involve allocating money to investments, or locating new warehouse facilities, or scheduling hospital operating rooms. In each case, multiple decisions need to be made in the best possible way while simultaneously satisfying a number of logical conditions (or constraints). The "best" or optimal solution might mean maximizing profits, minimizing costs, or achieving the best possible quality. Here are some representative examples of optimization problems:

## Finance and Investment

Working capital management involves deciding how much cash to allocate to different purposes (accounts receivable, inventory, etc.) across multiple time periods, to maximize interest earnings.

Capital budgeting involves deciding how much money to invest in projects that initially consume cash but later generate cash, to maximize a firm's return on capital.

Portfolio optimization -- creating "efficient portfolios" -- involves deciding how much money to invest in stocks or bonds to maximize return for a given level of risk, or to minimize risk for a target rate of return.

## Manufacturing

Job shop scheduling involves deciding how to assign work orders to different types of production equipment, to minimize delivery time or maximize equipment utilization.

Blending (of petroleum products, ores, animal feed, etc.) involves deciding how to combine raw materials of different types and grades, to meet demand while minimizing costs.

Cutting stock (for lumber, paper, etc.) involves deciding how to cut large sheets or timbers into smaller pieces, to meet demand while minimizing waste.

## Distribution and Networks

Routing (of goods, natural gas, electricity, digital data, etc.) involves deciding which paths items should move through to arrive at various destinations, to minimize costs or maximize throughput.

Loading (of trucks, rail cars, etc.) involves deciding how items of different sizes should be placed in vehicles so as to minimize wasted or unused space.

Scheduling of everything from workers to vehicles and meeting rooms involves deciding how resources should be allocate to various tasks in order to meet demand while minimizing overall costs.
