Methods for ranking efficient units in data envelopment analysis

This thesis focuses on the theory of models, data envelopment analysis and subsequent methods in ranking of obtained efficient units. The thesis is divided into three main parts. The first part describes the basic theoretical background of data envelopment analysis for different situations of inputs and outputs. It also contains basic information on specific models of CCR, BCC and SBM, including illustrative examples of their function. In the second part these models are adapted for use in the overall layout of production units which are the models of super efficiency and cross efficiency. Both methods include the description of the basic principles of their functioning. The aim is to compare the results of the various types of ranking using a practical example. This is included in the last part of the thesis. This chapter compares the results obtained using the models mentioned above. Data of the S & L branches were used as the input values for this work
