AHP Formula: Priority Weights and Consistency Ratio

Overview

This documentation page gives the complete AHP formula set: how to build the pairwise comparison matrix, derive priority weights (geometric mean and eigenvector methods), compute lambda-max, the Consistency Index, the Random Index table, and the Consistency Ratio, all with a fully worked, number-verified 4-criteria example you can reproduce by hand for an assignment or thesis.

This is a draft. The full worked-example body is generated and ready to expand here; the paired video production plan is attached to this page.
