The decision of the supplier selection is very important for a company to be successful. Selecting the right suppliers will decrease company’s purchasing cost, increase customer satisfaction and improve the competition capacity. This paper is dealt with supplier selection problem. AHP and TOPSIS, multiple criteria decision making methods, are applied together to select the most suitable supplier for a business firm. Quality, cost, delivery and service criteria that are mostly used in literature are defined as main criteria in the paper, and also their sub-criteria are defined. AHP method is used to determine the importance degree of main criteria and sub-criteria, TOPSIS method is developed to rank the suppliers. In AHP method, the weights of criterion and inconsistency rate are obtained by Super Decision 2.0.8 program. Microsoft Excel 2007 is used in TOPSIS method. Finally, the most important criterion is determined as “quality” and among the present suppliers of the business firm, “A2 supplier” is selected as the one which has the highest score.
