This study was conducted by using a consecutive application of the two methods of analysis. At the first stage all the companies in the sample have received the estimation of their efficiency by implementing the Data Envelopment Analysis, under given conditions of constant returns on the model parameters and solving the problem of maximizing the output parameters. On the second stage was conducted a cluster analysis of the DEA results by using the k-medians method and Euclidean distance calculation.Results. Based on the results of the empirical part of the research, the sample of companies has been divided into 8 isolated clusters that formed the basis of the typology of organizations in the international fashion retail industry. Each type of companies has been assign to a certain strategy type.
