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

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.

Installing Solver for Use

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

Refresher: Setting up a Linear Problem On Paper
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
