A firm will decide on the contractor for the execution of their factory building. Three contractors made it to the short list: firms A, B and C. The criteria that are considered are price quoted, quality of previous works, project management performance (PMP), and financial stability (FS) of the firm. Criteria are independent. The judgment matrix is given as:

From the pairwise comparisons the weights for each of the contractors with respect to criteria can be presented as:

(a) What is the desired solution for the firm? Check the preference matrix for consistency. Given we accept CR values 0.1 (10%) or less as an indication of consistency, what would be your conclusion? Would you ask for further analysis? Explain. (b) When comparing the contractors under the quality criterion, how do you phrase the question to the decision maker? Give an example. (c) Given the price quotations of the contractors A, B, and C are x, y, z ($), respectively, then how would the Price row under the contractors be specified?
