Software Systems and Technologies in The Conditions of Industry 4.0

Globally and in Europe, the effect of the application of digital technologies, and in particular in the manufacturing sector, has been identified as a strategic priority. In 2020, Bulgaria ranks last among the 28 EU member states in the European Commission's Index of Digital Entry into the Economy and Society (DESI). The research aims to study the technological intensity of industrial enterprises in Bulgaria and their level of digitalization. The results show that the use of automated control systems by industrial enterprises in the country is weak. The highest level of digitalization is shown by large enterprises, followed by medium and small enterprises. Bulgaria lags far behind the general trends in the EU for the introduction of a digital society and therefore it is necessary to take concrete measures and focus efforts to overcome the gap. Creating appropriate conditions for the introduction of Industry 4.0 will support the one hand the competitiveness of production and attract investment in the economy. On the other hand, will help increase efficiency in optimal use of resources.
