Use the Analytical Hierarchy Process in a decision$-$making scenario of your choosing $($no automobiles, laptops, or cell phones$).$ The scenario should satisfy the following:$$

Minimum of $5$ alternatives

Minimum of $5$ criteria including some measure of cost $($$$)$

Part $1$

Check the consistency of each pairwise comparison matrix using the consistency ratio and adjust if necessary.

Calculate the ranking of priority values for each alternative.

Comment on the results.

Part $2$

Repeat Part $1\mathrm{.}2$ with the cost criteria removed.

Calculate the Benefit$/$Cost ratio for each alternative by dividing $($element$-$wise$)$ the ranking of priority values by a normalized cost vector. Hint: A normalized cost vector is different from a normalized priority vector for the cost criteria.

Why would removing cost from the criterion matrix be preferred?

Deliverables should include data tables, processing method $($code$),$ and a brief write$-$up$.$
