Decision makers always consider many criteria in supplier selection problems to find out their best suppliers. Hence, the supplier selection problem belongs to the multiple criteria decision making (MCDM) problem. There are many approaches to solve the MCDM problem, the technique for order preference by similarity to ideal solution (TOPSIS) is one of often used methods. The study used the TOPSIS method and extended the method in supplier selection problems when decision makers set the target value of each criterion. After case testing, the proposed method and procedure can help the managers select the proper supplier in supply chain according to their target values in different criteria.
