Borda Count Method: this article provides a practical explanation of the Borda Count Method. In the traditional Borda count method the number of options determines the number of possible points. This pattern continues until the number of options are reached. However, it was the French mathematician and marine engineer Jean-Charles de Borda after whom the tool was named. This is illustrated by the example 'Effect of irrelevant alternatives' above. In the example, suppose that a voter is indifferent between Andrew and Brian, preferring both to Catherine and Catherine to David. If you need to handle a complete decision hierarchy, group inputs and alternative evaluation, use AHP-OS. Consider again the election from earlier.
