The transportation problem is well known in the operations research field. It has many practical applications and there are efficient algorithms specifically designed for this structure.

The articles in this section describe an Excel add-in designed to teach the primal simplex method for the solution of transportation problems.

Follow the links to see how the add-in is used. The contents are organized as steps of the simplex method.

The Teach Transportation add-in (treachtr.xla) and the demonstration Excel file (teachtransdem.xls) can be downloaded from the links at the left, near the bottom. If you don't know how to use add-ins please read the instructions.
