Analysis of the efficiency of companies in Serbia based on the DEA Super-Radial approach

Abstract

The issue of analyzing the company's efficiency factors is very challenging, current, significant, and complex. Based on that, this paper analyzes the efficiency of companies in Serbia based on the DEA Super-Radial approach. According to the results of the Super-Radial (Super-CCR-I and SuperCCR-O) model in 2021, none of the analyzed companies in Serbia was efficient. This means that the input/output elements were poorly managed. According to the results of the Super-Radial (SuperBCC-I) model in the same year in Serbia, two companies were efficient. These are JP EPS and NIS. Other observed companies were inefficient. According to the results of the Super-Radial (SuperBCC-O) model in 2021, three companies in Serbia were efficient. They are MERCATA VT, MY KIOSK GROUP, and KNEZ PETROL COMPANY. Other observed companies were inefficient. According to the projection, to achieve the planned efficiency, for example, at the DMU unit of JP EPS in 2021, it was necessary to reduce the number of employees by 51.93%, business assets by 57.18%, capital by 56.34%, business income by 3.00% and increase the net profit by 235.28 %. According to Slack analysis, for example, in the DMU unit of JP EPS, to increase efficiency, it is necessary to reduce the number of employees by 12469, business assets by 548953, capital by 339215 and increase the net profit by 35984.19 monetary units. The efficiency of companies in Serbia was influenced by numerous macro and micro factors: the economic climate, the efficiency of management of human resources, assets, capital, sales, and profit, etc. Their adequate control can significantly influence the achievement of the company's target profit in Serbia.
