However, these programs are generally able to compute a procedure known as Analysis of Variance (ANOVA). If you need to handle a complete decision hierarchy, group inputs and alternative evaluation, useAHP-OS. Imagine a person is being asked to vote on three pairs consisting of Option A, B and C. If the person prefers A over B and also B over C. We wouldnt need to ask someone if they prefer Option A over Option C, instead we can just infer this.
