COMPARISON OF LOGISTIC PERFORMANCES OF AIRLINE COMPANIES USING ENTROPY AND TOPSIS METHODS

In this study, a research was conducted to determine the relative logistical performance levels of airlines among each other. In order to determine the logistical performance levels of companies, cost, efficiency, service quality, price and management dimensions were taken as basis and unit operating cost, labor productivity, fleet efficiency, passenger load factor, timely performance, safety, flight frequency, income increase, net profit margin, market share sub-data were included in the study. The data was obtained from annual financial statements issued by the companies, from Skytrax reports and from studies in open source. The weights of the criteria were determined by experts from the aviation sector, Shannon Entropy method and simple weighting. The criteria were analyzed using the TOPSIS method for three different weight ratios. As a result of the research, it is seen that the rankings obtained by the expert opinion and entropy method are the same except that the first and second companies vary only by a 0.01 point difference. However, when the weight of each criterion is taken as equal, it is observed that the order of the alternatives is changed
