4. From a system thinking perspective, a manager of a private hospital wants to evaluate performance of its current suppliers (A1, A2, A3, and A4). The manager wants to construct an integrated AHP - DEA approach for bringing solution to the problem. Before constructing the DEA model, the manager wants to prioritize its suppliers employing traditional AHP analysis. The weights obtained from AHP method will be used in the DEA analysis. Assume that the consistency of the following pairwise comparison matrices are checked. Calculate the weights of the suppliers. Pairwise Comparison Matrix of Criteria Criterion 1 Al Pairwise Comparison Matrix of Suppliers with regard to (wrt) Criterion 1 A2 A3 A4 1/2 2 3 X 5 2 Criterion 2 Criterion 3 2 X 2 Criterion 1 Criterion 2 Criterion 3 1 Al A2 A3 A4 1 Pairwise Comparison Matrix of Suppliers wrt Criterion 2 A2 A3 A4 5 3 A2 1 1/X 1/5 A3 2 A4 Pairwise Comparison Matrix of Suppliers wrt Criterion 3 A1 A2 A3 A4 1 1/2 3 A2 1 X 3 1/3 1 3 A3 1 A4
