  1. Using Excel Solver for Linear Optimization Problems Wendy Pitchko Irene Meglis Shawn Lemko

  2. What is Solver? • Solver is an Add-In for Microsoft Excel which can solve optimization problems, including multiple constraint problems. • You can maximize, minimize, or set a target value to achieve.

  3. Installing Solver for Use • On Excel Menu, choose • Tools • Add-Ins...

  4. Installing Solver for Use • On Excel Menu, choose • Tools • Add-Ins... • Put a Check in the Box Next to ‘Solver Add-in’

  5. Using Solver • On Excel Menu, choose • Tools • Solver • This brings up the Solver Parameters box which will be discussed next.

  6. Recall the Cargo Problem from the last homework assignment… Our task is to maximize the profit for a shipping company using a combination of cargo weights without violating the given constraints Revenue is $250 per ton of cargo shipped Limit of 50,000 ft3 space and 100 tons Three types of Cargos with different densities, maximum available amounts Refresher: Setting up a Linear Problem On Paper

  7. Setting Up the Problem in Excel • The Objective Function

  8. Setting Up the Problem in Excel • The Objective Function • The Decision Variables (optimal values will be calculated by Solver)

  9. Setting Up the Problem in Excel • The Objective Function • The Decision Variables • The Constraints • Relationships

  10. Setting Up the Problem in Excel • The Objective Function • The Decision Variables • The Constraints • Relationships • Values
