Abstract

Decision making is at the heart of the managerial processes of many businesses. Problems such as the disclosure of the work to be done, the timing of the work, who will do the work, the determination of the resources to be used, require decisions to be determined in advance. If there were restrictions on the use of resources that were difficult to access and limited, there would be no major decision-making problem for the whole world. As the number of objectives increases, decision-making processes become more difficult. The management of decision-making processes is the most important task of the managers and the main objective in all business management is to make optimum decisions and make the most accurate decisions. In this study, multi-criteria decision making (MCDM) and logistics issues are handled together. The universe of the study consisted of all airline companies in Turkey. The sample of the study consisted of Turkey's leading national airline. The data of the study was collected with “Saaty scale”. The scale was mutually evaluated by the decision-making group. In the research, a mixed research model was used in which qualitative and quantitative methods were used together. As a result of this research, after determining the weight of the criteria with DEMATEL, the selection of the airline information technology department software company, it is determined that the first supplier will be the best choice by using MOORA and ARAS method.
