This thesis studies a real life case for supplier selection arising in a military organization that governs missile equipments, and proposes an integrated multi-criteria decision making model, which combines the techniques in data envelopment analysis (DEA), principal component analysis (PCA), and multi-attribute utility function decision theory, to help the management in the military organization select the most proper supplier for their equipment components. The decision making method consists of three phases: (1) Analyze and classify the important attributes in evaluating suppliers; (2) Understand the attributes that the management are most concerned with; (3) Construct a two-level hierarchical model for all attributes not in (2); (4) Select several most competent suppliers based on the model built in (3), using the AP efficiency rate in DEA and the efficiency rate in the integrated model combining methods in DEA and PCA; (5) Determine the best supplier using a multi-attribute utility function decision making method. In the case study, 20 qualified suppliers with relevant data were first selected. The developed integrated model is then applied to solve the supplier selection problem. At the fourth step, four competent suppliers were selected and the final decision was made based on the weighted sum of the utility values of the three attributes that the management is most concerned with. In the case, the three attributes are prices, life times, and warranty length. Additionally, Spearman rank test and Kendall’s Tau test are employed to compute the correlation between the supplier rankings computed by the AP model and the DEA-PCA model. Both test results indicate that the ranking produced by these two models are highly positively correlated.
