Item Developing an information system for credit risk rating using analytical hierarchy process (AHP)(Thesis (M.A.)-Bogazici University. Institute for Graduate Studies in the Social Sciences, 2008., 2008.) Tekin, Bahar.; Tükel, Ali.Credit risk management is one of the main activities of banks, and credit risk ratings are an essential part of the process. In the rating process statistical models and judgmental systems can be employed. At the evaluation of larger exposures, however, judgmental systems are preferred more than statistical models, although they are more costly. Different parties in a bank participate through the rating process and since performance assessment criteria of these parties are totally different from each other, disagreements in the rating process are inevitable. This thesis aims to show the differences between the judgments of two departments through the credit risk rating process in one of the banks in Turkey. Additionally the effect of group decision making on the accuracy of credit risk ratings is aimed at. The information system developed for credit risk rating is based on a descriptive and structured model called the Analytical Hierarchy Process (AHP).
