Alpha Associates undertook a project to setup a paper factory for Beta Incorporation. As a part of the project, the Alpha associate has to procure a costly machine and install in the factory. The criteria on which the machine is to be evaluated are as listed below.

• Price

• Safety

• Maintainability

• Useful Life.

A careful pairwise comparisons of the criteria in terms of their relative importance in the scale 1 to 9 with odd numbers by assuming 1 as the indifferent value (both criteria are equal) give the data as shown below.
Matrix of Pairwise Comparisons of Criteria Price Safety Maintainability Useful Life Price 1 3 1/3 5 Safety 1/3 1 1/5 3 Maintainability 3 5 1 9 Useful life 1/5 1/3 1/9 1 Find the priority vector for the criteria using AHP and check whether there is consistency among the values in the priority vector.AppendixLO1
