This free workbook contains seven example models from manufacturing / production. Click the model names to display each worksheet model in your browser.
You can use the worksheet that most closely models your situation as a starting point. Solving your real problem may require "scaling up" the model to include more variables and constraints -- but rest assured that you can solve your full-size problem with the power of our Excel Solver upgrades, even if it requires hundreds of thousands of variables!
